Changelog

All notable changes to this project are documented in this file.

1.4.1

Release date: 2024-09-26

This patch release comes with a fix to the GitRepository API to keep it backwards compatible by removing the default value for .spec.provider field when not set in the API. The controller will internally consider an empty value for the provider as the generic provider.

Fix:

  • GitRepo: Remove provider default value from API #1626

1.4.0

Release date: 2024-09-25

This minor release promotes the Bucket API to GA, and comes with new features, improvements and bug fixes.

Bucket

The Bucket API has been promoted from v1beta2 to v1 (GA). The v1 API is backwards compatible with v1beta2.

Bucket API now supports proxy through the field .spec.proxySecretRef and custom TLS client certificate and CA through the field .spec.certSecretRef.

Bucket API now also supports specifying a custom STS configuration through the field .spec.sts. This is currently only supported for the providers generic and aws. When specifying a custom STS configuration one must specify which STS provider to use. For the generic bucket provider we support the ldap STS provider, and for the aws bucket provider we support the aws STS provider. For the aws STS provider, one may use the default main STS endpoint, or the regional STS endpoints, or even an interface endpoint.

OCIRepository

OCIRepository API now supports proxy through the field .spec.proxySecretRef.

Warning: Proxy is not supported for cosign keyless verification.

GitRepository

GitRepository API now supports OIDC authentication for Azure DevOps repositories through the field .spec.provider using the value azure. See the docs for details here.

In addition, the Kubernetes dependencies have been updated to v1.31.1, Helm has been updated to v3.16.1 and various other controller dependencies have been updated to their latest version. The controller is now built with Go 1.23.

Fixes:

  • helm: Use the default transport pool to preserve proxy settings #1490

1.3.0

Release date: 2024-05-03

This minor release promotes the Helm APIs to GA, and comes with new features, improvements and bug fixes.

HelmRepository

The HelmRepository API has been promoted from v1beta2 to v1 (GA). The v1 API is backwards compatible with v1beta2.

For HelmRepository of type oci, the .spec.insecure field allows connecting over HTTP to an insecure non-TLS container registry.

To upgrade from v1beta2, after deploying the new CRD and controller, set apiVersion: source.toolkit.fluxcd.io/v1 in the YAML files that contain HelmRepository definitions. Bumping the API version in manifests can be done gradually. It is advised not to delay this procedure as the beta versions will be removed after 6 months.

HelmChart

The HelmChart API have been promoted from v1beta2 to v1 (GA). The v1 API is backwards compatible with v1beta2, with the exception of the removal of the deprecated field .spec.valuesFile which was replaced with spec.valuesFiles.

The HelmChart API was extended with support for Notation signature verification of Helm OCI charts.

A new optional field .spec.ignoreMissingValuesFiles has been added, which allows the controller to ignore missing values files rather than failing to reconcile the HelmChart.

OCIRepository

The OCIRepository API was extended with support for Notation signature verification of OCI artifacts.

A new optional field .spec.ref.semverFilter has been added, which allows the controller to filter the tags based on regular expressions before applying the semver range. This allows picking the latest release candidate instead of the latest stable release.

In addition, the controller has been updated to Kubernetes v1.30.0, Helm v3.14.4, and various other dependencies to their latest version to patch upstream CVEs.

Improvements:

  • Promote Helm APIs to source.toolkit.fluxcd.io/v1 (GA) #1428
  • Add .spec.ignoreMissingValuesFiles to HelmChart API #1447
  • Implement .spec.ref.semverFilter in OCIRepository API #1407
  • Helm: Allow insecure registry login #1412
  • Add support for Notation verification to HelmChart and OCIRepository #1075
  • Various dependency updates #1442 #1450 #1469 #1378

Fixes:

  • Bind cached helm index to the maximum index size #1457
  • Remove genclient:Namespaced tag #1386

1.2.5

Release date: 2024-04-04

This patch release comes with improvements to the HelmChart name validation and adds logging sanitization of connection error messages for Bucket sources.

Fixes:

  • Improve chart name validation #1377
  • Sanitize URLs for bucket fetch error messages #1430

Improvements:

  • Update controller-gen to v0.14.0 #1399

1.2.4

Release date: 2024-02-01

This patch release updates the Kubernetes dependencies to v1.28.6 and various other dependencies to their latest version to patch upstream CVEs.

Improvements:

1.2.3

Release date: 2023-12-14

This patch release updates the controller's Helm dependency to v3.13.3.

Improvements:

  • Update Helm to v3.13.3 #1325
  • helmrepo: Remove migration log/event #1324

1.2.2

Release date: 2023-12-11

This patch release addresses an issue with AWS ECR authentication introduced in v1.2.0.

In addition, a variety of dependencies have been updated. Including an update of the container base image to Alpine v3.19.

Fixes:

  • Address issue with authenticating towards AWS ECR #1318 #1321

Improvements:

1.2.1

Release date: 2023-12-08

This patch release ensures the controller is built with the latest Go 1.21.x release, to mitigate multiple security vulnerabilities which were published shortly after the release of v1.2.0.

In addition, a small number of dependencies have been updated to their latest version.

Improvements:

  • Update dependencies #1309

1.2.0

Release date: 2023-12-05

This minor release comes with API changes, bug fixes and several new features.

Bucket

A new field, .spec.prefix, has been added to the Bucket API, which enables server-side filtering of files if the object's .spec.provider is set to generic/aws/gcp.

OCIRepository and HelmChart

Two new fields, .spec.verify.matchOIDCIdentity.issuer and .spec.verify.matchOIDCIdentity.subject have been added to the HelmChart and OCIRepository APIs. If the image has been keylessly signed via Cosign, these fields can be used to verify the OIDC issuer of the Fulcio certificate and the OIDC identity's subject respectively.

HelmRepository

A new boolean field, .spec.insecure, has been introduced to the HelmRepository API, which allows connecting to a non-TLS HTTP container registry. It is only considered if the object's .spec.type is set to oci.

From this release onwards, HelmRepository objects of type OCI are treated as static objects, i.e. they have an empty status. Existing objects undergo a one-time automatic migration and new objects will be undergo a one-time reconciliation to remove any status fields.

Additionally, the controller now performs a shallow clone if the .spec.ref.name of the GitRepository object points to a branch or a tag.

Furthermore, a bug has been fixed, where the controller would try to authenticate against public OCI registries if the HelmRepository object has a reference to a Secret containing a CA certificate.

Lastly, dependencies have been updated to their latest version, including an update of Kubernetes to v1.28.4.

Fixes:

  • Address miscellaneous issues throughout code base #1257
  • helmrepo: only configure tls login option when required #1289
  • oci: rename OCIChartRepository.insecure to insecureHTTP #1299
  • Use bitnami Minio oci chart for e2e #1301

Improvements:

  • build(deps): bump Go dependencies #1260 #1261 #1269 #1291
  • build(deps): bump the ci group dependencies #1265 #1266 #1272 #1277 #1281 #1285 #1296 #1303
  • bucket: Add prefix filtering capability #1228
  • Static HelmRepository OCI #1243
  • cosign: allow identity matching for keyless verification #1250
  • Upgrade go-git to v5.10.0 #1271
  • storage: change default file permissions #1276
  • Update dependencies to Kubernetes v1.28 #1286
  • Add .spec.insecure to HelmRepository for type: oci #1288
  • Update Git dependencies #1300
  • Update Go dependencies #1304

1.1.2

Release date: 2023-10-11

This patch release fixes a bug where OCIRepository objects can't be consumed when the OCI image layer contains symlinks.

Fixes:

  • oci: Skip symlinks found in upstream artifacts #1246

Improvements:

  • build(deps): bump the ci group with 1 update #1256

1.1.1

Release date: 2023-09-18

This is a patch release that fixes a regression introduced in v1.1.0 where HelmRepository objects would not be reconciled if they provided a TLS Secret using .spec.secretRef with a type other than Opaque or kubernetes.io/tls.

In addition, the URL lookup strategy for Buckets has been changed from path to auto, to widen support for S3-compatible object storage services.

Lastly, several dependencies have been updated to their latest versions.

Fixes:

  • bucket: use auto lookup type #1222
  • helmrepo: fix Secret type check for TLS via .spec.secretRef #1225
  • Upgrade github.com/fluxcd/pkg/{git,git/gogit} #1236

Improvements:

  • build(deps): bump the ci group dependencies #1213 #1224 #1230 #1235
  • docs: Add missing pem-encoding reference #1216
  • build(deps): bump github.com/cyphar/filepath-securejoin from 0.2.3 to 0.2.4 #1227

1.1.0

Release date: 2023-08-23

This minor release comes with API changes, bug fixes and several new features.

All APIs that accept TLS data have been modified to adopt Secrets of type kubernetes.io/tls. This includes:

  • HelmRepository: The field .spec.secretRef has been deprecated in favor of a new field .spec.certSecretRef. This field is also supported by OCI HelmRepositories.
  • OCIRepository: Support for thecaFile, keyFile and certFile keys in the Secret specified in .spec.certSecretRef have been deprecated in favor of ca.crt, tls.key and tls.crt. Also, the Secret now must be of type Opaque or kubernete.io/tls.
  • GitRepository: CA certificate can now be provided in the Secret sepcified in .spec.secretRef using the ca.crt key, which takes precedence over the existing caFile key.

Furthermore, GitRepository has a couple of new features:

  • Proxy support: A new field .spec.proxySecretRef has been introduced which can be used to specify the proxy configuration to use for all remote Git operations related to the particular object.
  • Tag verification: The field .spec.verification.mode now supports the following values:
    • HEAD: Verify the HEAD of the Git repository.
    • Tag: Verify the tag specified in .spec.ref
    • TagAndHead: Verify the tag specified in .spec.ref and the commit it points to.

Starting with this version, the controller now stops exporting an object's metrics as soon as the object has been deleted.

In addition, the controller now consumes significantly less CPU and memory when reconciling Helm repository indexes.

Lastly, a new flag --interval-jitter-percentage has been introduced which can be used to specify a jitter to the reconciliation interval in order to distribute the load more evenly when multiple objects are set up with the same interval.

Improvements:

  • gitrepo: Add support for specifying proxy per GitRepository #1109
  • helmrepo: add .spec.certSecretRef for specifying TLS auth data #1160
  • Update docs on Azure identity #1167
  • gitrepo: document limitation of spec.ref.name with Azure Devops #1175
  • ocirepo: add cosign support for insecure HTTP registries #1176
  • Handle delete before adding finalizer #1177
  • Store Helm indexes in JSON format #1178
  • Unpin go-git and update to v5.8.1 #1179
  • controller: jitter requeue interval #1184
  • cache: ensure new expiration is persisted #1185
  • gitrepo: add support for Git tag verification #1187
  • Update dependencies #1191
  • Adopt Kubernetes style TLS Secrets #1194
  • Update dependencies #1196
  • Helm OCI: Add support for TLS registries with self-signed certs #1197
  • Update dependencies #1202
  • Preserve url encoded path in normalized helm repository URL #1203
  • Fix link ref in API docs #1204

Fixes:

  • Fix the helm cache arguments #1170
  • Delete stale metrics on object delete #1183
  • Disable system-wide git config in tests #1192
  • Fix links in API docs #1200

1.0.1

Release date: 2023-07-10

This is a patch release that fixes the AWS authentication for cross-region ECR repositories.

Fixes:

  • Update fluxcd/pkg/oci to fix ECR cross-region auth #1158

1.0.0

Release date: 2023-07-03

This is the first stable release of the controller. From now on, this controller follows the Flux 2 release cadence and support pledge.

Starting with this version, the build, release and provenance portions of the Flux project supply chain provisionally meet SLSA Build Level 3.

This release includes several minor changes that primarily focus on addressing forgotten and obsolete bits in the logic related to GitRepository objects.

Including a removal of the OptimizedGitClones feature flag. If your Deployment is configured to disable this flag, you should remove it.

In addition, dependencies have been updated to their latest version, including an update of Kubernetes to v1.27.3.

For a comprehensive list of changes since v0.36.x, please refer to the changelog for v1.0.0-rc.1, v1.0.0-rc.3 and v1.0.0-rc.4.

Improvements:

  • gitrepo: remove OptimizedGitClones as a feature gate #1124 #1126
  • Update dependencies #1127 #1147
  • Update Cosign to v2.1.0 #1132
  • Align go.mod version with Kubernetes (Go 1.20) #1134
  • Add the verification key to the GitRepository verified status condition
  • #1136
  • gitrepo: remove obsolete proxy docs #1144

1.0.0-rc.5

Release date: 2023-06-01

This release candidate fixes a regression introduced in 1.0.0.-rc.4 where support for Git servers that exclusively use v2 of the wire protocol like Azure Devops and AWS CodeCommit was broken.

Lastly, the controller's dependencies were updated to mitigate CVE-2023-33199.

Improvements:

  • build(deps): bump github.com/sigstore/rekor from 1.1.1 to 1.2.0 #1107

Fixes:

  • Bump fluxcd/pkg/git/gogit to v0.12.0 #1111

1.0.0-rc.4

Release date: 2023-05-26

This release candidate comes with support for Kubernetes v1.27 and Cosign v2. It also enables the use of annotated Git tags with .spec.ref.name in GitRepository. Furthermore, it fixes a bug related to accessing Helm OCI charts on ACR using OIDC auth.

Improvements:

  • build(deps): bump helm/kind-action from 1.5.0 to 1.7.0 #1100
  • build(deps): bump sigstore/cosign-installer from 3.0.3 to 3.0.5 #1101
  • build(deps): bump actions/setup-go from 4.0.0 to 4.0.1 #1102
  • Update cosign to v2 #1096
  • build(deps): bump github.com/sigstore/rekor from 0.12.1-0.20220915152154-4bb6f441c1b2 to 1.1.1 #1083
  • Update controller-runtime and Kubernetes dependencies #1104
  • Update dependencies; switch to go-git/go-git and pkg/tar #1105

1.0.0-rc.3

Release date: 2023-05-12

This release candidate introduces the verification of the Artifact digest in storage during reconciliation. This ensures that the Artifact is not tampered with after it was written to storage. When the digest does not match, the controller will emit a warning event and remove the file from storage, forcing the Artifact to be re-downloaded.

In addition, files with executable permissions are now archived with their mode set to 0o744 instead of 0o644. Allowing the extracted file to be executable by the user.

Lastly, the controller's dependencies were updated to mitigate CVE-2023-1732 and CVE-2023-2253, and the controller base image was updated to Alpine 3.18.

Improvements:

  • Verify digest of Artifact in Storage #1088
  • build(deps): bump github.com/cloudflare/circl from 1.3.2 to 1.3.3 #1092
  • build(deps): bump github.com/docker/distribution from 2.8.1+incompatible to 2.8.2+incompatible #1093
  • storage: set 0o744 for files with exec mode set #1094

1.0.0-rc.2

Release date: 2023-05-09

This release candidate comes with various updates to the controller's dependencies, most notable, Helm was updated to v3.11.3.

Improvements:

  • Update dependencies #1086
  • Set RecoverPanic globally across controllers #1077
  • Move controllers to internal/controller #1076

1.0.0-rc.1

Release date: 2023-03-30

This release candidate promotes the GitRepository API from v1beta2 to v1. The controller now supports horizontal scaling using sharding based on a label selector.

In addition, support for Azure Workload Identity was added to OCIRepositories, Buckets and HelmRepositories when using provider: azure.

Highlights

API changes

The GitRepository kind was promoted from v1beta2 to v1 (GA) and deprecated fields were removed.

The common types Artifact, Conditions and the Source interface were promoted to v1.

The gitrepositories.source.toolkit.fluxcd.io CRD contains the following versions:

  • v1 (storage version)
  • v1beta2 (deprecated)
  • v1beta1 (deprecated)

Upgrade procedure

The GitRepository v1 API is backwards compatible with v1beta2, except for the following:

  • the deprecated field .spec.gitImplementation was removed
  • the unused field .spec.accessFrom was removed
  • the deprecated field .status.contentConfigChecksum was removed
  • the deprecated field .status.artifact.checksum was removed
  • the .status.url was removed in favor of the absolute .status.artifact.url

To upgrade from v1beta2, after deploying the new CRD and controller, set apiVersion: source.toolkit.fluxcd.io/v1 in the YAML files that contain GitRepository definitions and remove the deprecated fields if any. Bumping the API version in manifests can be done gradually. It is advised to not delay this procedure as the beta versions will be removed after 6 months.

Sharding

Starting with this release, the controller can be configured with --watch-label-selector, after which only objects with this label will be reconciled by the controller.

This allows for horizontal scaling, where source-controller can be deployed multiple times with a unique label selector which is used as the sharding key.

Note that this also requires configuration of the --storage-adv-addr to a unique address (in combination with a proper Service definition). This to ensure the Artifacts handled by the sharding controller point to a unique endpoint.

In addition, Source object kinds which have a dependency on another kind (i.e. a HelmChart on a HelmRepository) need to have the same labels applied to work as expected.

Full changelog

Improvements:

  • GA: Promote GitRepository API to source.toolkit.fluxcd.io/v1 #1056
  • Add reconciler sharding capability based on label selector #1059
  • Support Azure Workload Identity #1048
  • Update dependencies #1062
  • Update workflows #1054

0.36.1

Release date: 2023-03-20

This release fixes a bug where after reading a .sourceignore file in a subdirectory, the controller could start to ignore files from directories next to the directory the .sourceignore file was placed in.

Fixes:

  • Update sourceignore to fix pattern domain bug #1050

0.36.0

Release date: 2023-03-08

This release changes the format of the Artifact Revision field when using a GitRepository with a .spec.ref.name set (introduced in v0.35.0), changing it from sha1:<commit> to <name>@sha1:<commit>. Offering a more precise reflection of the revision the Artifact was created from.

In addition, klog is now configured to log using the same logger as the rest of the controller (providing a consistent log format).

Lastly, the controller is now built using Go 1.20, and the dependencies have been updated to their latest versions.

Improvements:

  • Advertise absolute reference in Artifact for GitRepository name ref #1036
  • Update Go to 1.20 #1040
  • Update dependencies #1040 #1041 #1043
  • Use logger.SetLogger to also configure klog #1044

0.35.2

Release date: 2023-02-23

This release reduces the amount of memory consumed by the controller when reconciling HelmRepositories, by using only the digest of the YAML file as the Revision of the Artifact instead of the stable sorted version of the entire index. This aligns with the behavior before v0.35.0, and is therefore considered a bug fix.

In addition, the dependencies have been updated to include some minor security patches.

Note that v0.35.0 contains breaking changes. Please refer to the changelog entry for more information.

Fixes:

  • helm: only use Digest to calculcate index revision #1035

Improvements:

  • Update dependencies #1036

0.35.1

Release date: 2023-02-17

This release addresses a hypothetical issue with the Artifact Digest field validation, where a patch of the Artifact could fail to be applied to an object due to the lack of an omitempty tag on the optional field. In reality, this issue is not possible to encounter, as the Digest field is always set when the Artifact is created.

Note that v0.35.0 contains breaking changes. Please refer to the changelog entry for more information.

Fixes:

  • api: omit empty Digest in Artifact #1031

0.35.0

Release date: 2023-02-16

This release introduces a new format for the Artifact Revision, and deprecates the Checksum field in favor of a new Digest field. In addition, it adds support for Git reference names in a GitRepository, and comes with the usual collection of dependency updates.

Highlights

Support for Git reference names

Starting with this version, it is possible to define a Git Reference in a GitRepository using .spec.ref.name.

This opens the door to a range of functionalities not available before, as it for example allows the controller to follow pull (refs/pull/<id>/head) or merge (refs/merge-requests/<id>/head) requests, and allows a transition from the HEAD of a branch (refs/heads/main) to a tag (refs/tags/v0.1.0) by changing a single field value.

Refer to the GitRepository specification for more details.

Introduction of Artifact Digest

The Artifact of a Source will now advertise a Digest field containing the checksum of the file advertised in the Path, and the alias of the algorithm used to calculate it. Creating a "digest" in the format of <algo>:<checksum>.

The algorithm is configurable using the newly introduced --artifact-digest-algo flag, which allows configuration of other algorithms (sha384, sha512, and blake3) than the hardcoded sha256 default of the now deprecated Checksum field.

Please note that until the Checksum is fully deprecated, changing the algorithm is not yet advised (albeit supported), as this will result in a double computation.

⚠️ Breaking changes

Artifact Revision format

The Revision format for an Artifact consisting of a named pointer (a Git branch or tag) and/or a specific revision (a Git commit SHA or other calculated checksum) has changed to contain an @ separator opposed to /, and includes the algorithm alias as a prefix to a checksum (creating a "digest"). In addition, HEAD is no longer used as a named pointer for exact commit references, but will now only advertise the commit itself.

For example:

  • main/1eabc9a41ca088515cab83f1cce49eb43e84b67f => main@sha1:1eabc9a41ca088515cab83f1cce49eb43e84b67f
  • HEAD/5394cb7f48332b2de7c17dd8b8384bbc84b7e738 => sha1:5394cb7f48332b2de7c17dd8b8384bbc84b7e738
  • tag/55609ff9d959589ed917ce32e6bc0f0a36809565f308602c15c3668965979edc => tag@sha256:55609ff9d959589ed917ce32e6bc0f0a36809565f308602c15c3668965979edc
  • 8fb62a09c9e48ace5463bf940dc15e85f525be4f230e223bbceef6e13024110c => sha256:8fb62a09c9e48ace5463bf940dc15e85f525be4f230e223bbceef6e13024110c

When the storage of the controller is backed by a Persistent Volume, the rollout of this new format happens for the next new revision the controller encounters. Otherwise, the new revision will be advertised as soon as the Artifact has been reproduced after the controller is deployed.

Other Flux controllers making use of an Artifact are aware of the change in format, and work with it in a backwards compatible manner. Avoiding observing a change of revision when this is actually just a change of format. If you programmatically make use of the Revision, please refer to the TransformLegacyRevision helper to allow a transition period in your application.

For more information around this change, refer to RFC-0005.

Deprecation of Artifact Checksum

The Checksum field of an Artifact has been deprecated in favor of the newly introduced Digest. Until the deprecated field is removed in the next version of the API, the controller will continue to produce the SHA-256 checksum in addition to the digest. Changing the algorithm used to produce the digest using --artifact-digest-algo is therefore not yet advised (albeit supported), as this will result in a double computation.

For more information around this change, refer to RFC-0005.

Full changelog

Improvements:

  • Introduction of Digest and change of Revision format #1001
  • Improve HelmRepository type switching from default to oci #1016
  • Apply default permission mode to all files/dirs in an artifact archive #1020
  • Add support for checking out Git references #1026
  • Update dependencies #1025 #1028 #1030

Fixes:

  • Normalize Helm repository URL with query params properly #1015
  • Prevent panic when cloning empty Git repository #1021

0.34.0

Release date: 2023-01-31

This prerelease comes with support for HTTPS bearer token authentication for Git repository. The GitRepository authentication Secret is expected to contain the bearer token in .data.bearerToken.

The caching of Secret and ConfigMap resources is disabled by default to improve memory usage. To opt-out from this behavior, start the controller with: --feature-gates=CacheSecretsAndConfigMaps=true.

All the Source kinds now support progressive status updates. The progress made by the controller during reconciliation of a Source is reported immediately in the status of the Source object.

In addition, the controller dependencies have been updated to Kubernetes v1.26.

⚠️ Breaking change: When using SSH authentication in GitRepository, if the referenced Secret contained .data.username, it was used as the SSH user. With this version, SSH user will be the username in the SSH address. For example, if the Git repository address is ssh://flux@example.com, flux will be used as the SSH user during SSH authentication. When no username is specified, git remains the default SSH user.

Improvements:

  • Garbage collection lock file ignore tests #992
  • purge minio test container at the end of tests #993
  • Introduce Progressive status #974

0.33.0

Release date: 2022-12-20

This prerelease comes with dedicated mux for the controller's fileserver. All code references to libgit2 were removed, and the spec.gitImplementation field is no longer being honored, but rather go-git is used. For more information, refer to version 0.32.0's changelog, which started libgit2's deprecation process.

The controller's garbage collection now takes into consideration lock files.

The feature gate ForceGoGitImplementation was removed, users passing it as their controller's startup args will need to remove it before upgrading.

Fixes:

  • git: Fix issue with recurseSubmodules #975
  • Fix aliased chart dependencies resolution #988

Improvements:

  • fileserver: Use new ServeMux #972
  • Remove libgit2 and git2go from codebase #977

0.32.1

Release date: 2022-11-18

This prerelease rectifies the v0.32.0 release by retracting the previous Go version, bumping the controller api version and the controller deployment.

0.32.0

Release date: 2022-11-17

This prerelease comes with a major refactoring of the controller's Git operations. The go-git implementation now supports all Git servers, including Azure DevOps, which previously was only supported by libgit2.

This version initiates the soft deprecation of the libgit2 implementation. The motivation for removing support for libgit2 being:

  • Reliability: over the past months we managed to substantially reduce the issues users experienced, but there are still crashes happening when the controller runs over longer periods of time, or when under intense GC pressure.
  • Performance: due to the inherit nature of libgit2 implementation, which is a C library called via CGO through git2go, it will never perform as well as a pure Go implementations. At scale, memory pressure insues which then triggers the reliability issues above.
  • Lack of Shallow Clone Support.
  • Maintainability: supporting two Git implementations is a big task, even more so when one of them is in a complete different tech stack. Given its nature, to support libgit2, we have to maintain an additional repository. Statically built libgit2 libraries need to be cross-compiled for all our supported platforms. And a lot of "unnecessary" code has to be in place to make building, testing and fuzzing work seamlessly.

As a result the field spec.gitImplementation is ignored and the reconciliations will use go-git. To opt-out from this behaviour, start the controller with: --feature-gates=ForceGoGitImplementation=false.

Users having any issues with go-git should report it to the Flux team, so any issues can be resolved before support for libgit2 is completely removed from the codebase.

Improvements:

  • Refactor Git operations and introduce go-git support for Azure DevOps and AWS CodeCommit #944
  • Use Flux Event API v1beta1 #952
  • gogit: Add new ForceGoGitImplementation FeatureGate #945
  • Remove nsswitch.conf creation from Dockerfile #958
  • Update dependencies #960 #950 #959
  • Upgrade to azure-sdk-for-go/storage/azblob v0.5.1 #931

0.31.0

Release date: 2022-10-21

This prerelease comes with support for Cosign verification of Helm charts. The signatures verification can be configured by setting HelmChart.spec.verify with provider as cosign and a secretRef to a secret containing the public key. Cosign keyless verification is also supported, please see the HelmChart API documentation for more details.

In addition, the controller dependencies have been updated to Kubernetes v1.25.3 and Helm v3.10.1.

Improvements:

  • Implement Cosign verification for HelmCharts #925
  • Update dependencies #942

Fixes:

  • Allow deleting suspended objects #937

0.30.1

Release date: 2022-10-10

This prerelease enables the use of container-level SAS tokens when using Bucket objects to access Azure Storage. The Azure SDK error message has also been enriched to hint Flux users the potential reasons in case of failure.

Improvements:

  • List objects when checking if bucket exists to allow use of container-level SAS token #906

0.30.0

Release date: 2022-09-29

This prerelease adds support for Cosign verification in OCIRepository source. The signatures verification can be configured by setting OCIRepository.spec.verify with provider as cosign and a secretRef to a secret containing the public key. Cosign keyless verification is also supported, please see the OCIRepository API documentation for more details.

It also comes with strict validation rules for API fields which define a (time) duration. Effectively, this means values without a time unit (e.g. ms, s, m, h) will now be rejected by the API server. To stimulate sane configurations, the units ns, us and µs can no longer be configured, nor can h be set for fields defining a timeout value.

In addition, the controller dependencies have been updated to Kubernetes controller-runtime v0.13.

⚠️ Breaking changes:

  • .spec.interval new validation pattern is "^([0-9]+(\\.[0-9]+)?(ms|s|m|h))+$"
  • .spec.timeout new validation pattern is "^([0-9]+(\\.[0-9]+)?(ms|s|m))+$"

Improvements:

Fixes:

  • Handle nil OCI authenticator with malformed registry #897

0.29.0

Release date: 2022-09-09

This prerelease adds support for non-TLS container registries such as Kubernetes Kind Docker Registry. Connecting to an in-cluster registry over plain HTTP, requires setting the OCIRepository.spec.insecure field to true.

⚠️ Breaking change: The controller logs have been aligned with the Kubernetes structured logging. For more details on the new logging structure please see: fluxcd/flux2#3051.

Improvements:

  • Align controller logs to Kubernetes structured logging #882
  • [OCIRepository] Add support for non-TLS insecure container registries #881
  • Fuzz optimisations #886

Fixes:

  • [OCI] Static credentials should take precedence over the OIDC provider #884

0.28.0

Release date: 2022-08-29

Improvements:

  • OCIRepo docs: auto-login setup details #862
  • Add Support for SAS keys in Azure Blob #738
  • Use sourceignore from fluxcd/pkg/sourceignore #864
  • Update dependencies #869

0.26.1

Release date: 2022-08-11

This prerelease comes with panic recovery, to protect the controller from crashing when reconciliations lead to a crash. It also adds OCI documentation and improvements to the controllers CI pipeline.

Improvements:

  • Enable panic recovery #859

Release date: 2022-06-02

This prerelease fixes some race conditions in the libgit2 managed ssh smart subtransport.

Fixes:

  • libgit2/managed: fix race issues in ssh transport #753

0.25.0

Release date: 2022-06-01

This prerelease adds support for Helm OCI. Users can specify .spec.type of a HelmRepository to use an OCI repository instead of an HTTP/S Helm repository.

Please note that this currently has a couple of limitations (which will be addressed in a future release):

  • Chart dependencies from OCI repositories are not supported. #722
  • Custom CA certificates are not supported. #723

An example of OCI HelmRepository can be found here.

A new flag --feature-gate has been added to disable/enable new experimental features. It works in a similar manner to Kubernetes feature gates.

The libgit2 managed transport feature has been enabled by default. Furthermore, a few changes have been made to make the feature more stable and enable quicker clones. Users that want to opt out and use the unmanaged transports may do so by passing the flag --feature-gate=GitManagedTransport=false, but please note that we encourage users not to do so.

GitRepository reconciliation has been made more efficient by adding support for no-op clones, when checking out repositories using branches or tags. This feature is also enabled by default, and users can opt out by passing the flag --feature-gate=OptimizedGitClones=false. Please note that this feature is only active when the managed transport feature is enabled. Disabling managed transports, quietly disables optimzed Git clones.

Improvements:

  • Optimise clone operations #665
  • [RFC 0002] Flux OCI support for Helm #690
  • Add Git test coverage for supported algorithms #708
  • Add new flag --ssh-hostkey-algos #711
  • libgit2: Disable connection caching #713
  • Update dependencies #717
  • libgit2: enable managed transport by default #718

  • libgit2: Pass ctx to all the transport opts #743

Fixes:

  • Ensure git status is checked at the correct time #575
  • libgit2: recover from git2go panic #707
  • Remove minio region #715
  • GitRepositoryReconciler no-op clone improvements #724

Improvements:

  • summarize: Consider obj status condition in result #703
  • Update dependencies #705

Fixes:

  • docs: Remove all traces of "identity.pub" from docs #699

0.24.3

Release date: 2022-04-28

This prerelease prevents Reconciling and ArtifactOutdated conditions from being set on a HelmRepository when the checksum of a cached repository index changes.

Fixes:

  • helmrepo: same revision different checksum scenario #691

0.24.2

Release date: 2022-04-26

This prerelease improves the memory consumption while reconciling a HelmRepository, by only validating the YAML of a fetched index when the checksum of the retrieved file differs from the current Artifact.

Fixes:

  • helm: optimise repository index loading #685
  • tests: Fix flakiness of git related tests #686

0.24.1

Release date: 2022-04-22

This prerelease fixes a regression bug where the controller would panic in further to be identified edge-case scenarios in which a HelmRepository Artifact would not have a size.

Fixes:

  • Fix panic when HelmRepository's artifact size is nil #683

0.24.0

Release date: 2022-04-19

This prerelease enables the Helm chart dependency manager to make use of the opt-in memory cache introduced in v0.23.0, revises the file permissions set by the controller, and updates various dependencies.

⚠️ Breaking change: From this release on, the RUNTIME_NAMESPACE environment variable is no longer taken into account to configure the advertised HTTP/S address of the storage. Instead, variable substitution must be used, as described in the changelog entry for v0.5.2.

Improvements:

  • Change all file permissions to octal format #653
  • Enable dependency manager to use in-memory cache #667
  • Update libgit2 image to v1.3.1 #671
  • Remove hostname hyphen split block #672
  • Update dependencies #675 #676 #677

0.23.0

Release date: 2022-04-12

This prerelease introduces new retention options for Garbage Collection, a new opt-in in-memory cache for HelmRepository index files, improves notifications following reconciling failures, brings ways to configure Key Exchange Algorithms, plus some extra housekeeping awesomeness.

Garbage Collection is enabled by default, and now its retention options are configurable with the flags: --artifact-retention-ttl (default: 60s) and --artifact-retention-records (default: 2). They define the minimum time to live and the maximum amount of artifacts to survive a collection.

A new notification is now emitted to identify recovery from failures. It is triggered when a failed reconciliation is followed by a successful one, and the notification message is the same that's sent in usual successful source reconciliation message about the stored artifact.

The opt-in in-memory cache for HelmRepository addresses issues where the index file is loaded and unmarshalled in concurrent reconciliation resulting in a heavy memory footprint. It can be configured using the flags: --helm-cache-max-size, --helm-cache-ttl, --helm-cache-purge-interval.

The Key Exchange Algorithms used when establishing SSH connections are based on the defaults configured upstream in go-git and golang.org/x/crypto. Now this can be overriden with the flag --ssh-kex-algos. Note this applies to the go-git gitImplementation or the libgit2 gitImplementation but only when Managed Transport is being used.

Managed Transport for libgit2 now introduces self-healing capabilities, to recover from failure when long-running connections become stale.

The exponental back-off retry can be configured with the new flags: --min-retry-delay (default: 750ms) and --max-retry-delay (default: 15min). Previously the defaults were set to 5ms and 1000s, which in some cases impaired the controller's ability to self-heal (e.g. retrying failing SSH connections).

Introduction of a secure directory loader which improves the handling of Helm charts paths.

Improvements:

  • update toolkit.fluxcd.io docs links #651
  • Add optional in-memory cache of HelmRepository index files #626
  • Add flag to allow configuration of SSH kex algos #655
  • Garbage collect with provided retention options #638
  • Avoid event logging GC failure #659
  • Add notify() in all the reconcilers #624
  • Remove leftover timeout in reconcilers #660
  • libgit2: managed transport improvements #658
  • helm: introduce customized chart loaders #663
  • Add flags to configure exponential back-off retry #664

0.22.5

Release date: 2022-03-30

This prerelease improves the Status API of the Source objects to reflect more accurate Status Condition information.

In addition, it also fixes a bug in go-git implementation due to which cloning public Git repository failed without any credentials since version 0.17.0, and some general stability improvements in the libgit2 experimental managed transport.

Improvements:

  • Align fuzzing deps #644
  • Separate positive polarity conditions for ArtifactInStorage #646
  • Removes empty credentials from Basic Auth #648
  • libgit2: fix access to nil t.stdin and improve observability #649

0.22.4

Release date: 2022-03-28

This prerelease improves on the experimental managed transport overall stability. Changes of note:

  • SSH connections now being reused across git operations.
  • Leaked HTTP connections are now fixed.
  • The long-standing SSH intermittent errors are addressed by the cached connections.

Fixes:

  • Various fixes for managed transport #637

0.22.3

Release date: 2022-03-25

This prerelease fixes a regression bug introduced in v0.22.0, which would cause a GitRepository to end up in a Stalled state if an include did not have an Artifact available.

Fixes:

  • gitrepo: Do not stall when no included artifact #639
  • Fix dpanic issue when logging odd number of args #641

0.22.2

Release date: 2022-03-23

This prerelease ensures (Kubernetes) Event annotations are prefixed with the FQDN of the Source API Group. For example, revision is now source.toolkit.fluxcd.io/revision.

This to facilitate improvements to the notification-controller, where annotations prefixed with the FQDN of the Group of the Involved Object will be transformed into "fields".

Fixes:

  • Prefix event annotations with API Group FQDN #632

0.22.1

Release date: 2022-03-23

This prerelease fixes a regression in which .sourceignore rules for a GitRepository would not be matched correctly.

Fixes:

  • fix: configure domain for .sourceignore rules #629

0.22.0

Release date: 2022-03-17

This prerelease comes with new reconcilers which make use of fluxcd/pkg utilities for common runtime operations, and graduates the API to v1beta2.

⚠️ It is required to update the source-controller Custom Resource Definitions on your cluster and/or in Git.

Breaking changes

  • Bucket resources do now take the provided etag for object storage items into account during the calculation of the revision. As a result, items will no longer be downloaded on every reconcile if none of them have changed.
  • HelmChart resources do now advertise the observed chart name (.status.observedChartName) and Source (reference) Artifact revision (.status.observedSourceArtifactRevision) in the Status. The information is used to more efficiently react to source revision and/or chart changes.

Features and Improvements

API specifications in a user-friendly format

The new specifications for the v1beta2 API have been written in a new format with the aim to be more valuable to a user. Featuring separate sections with examples, and information on how to write and work with them.

Artifact now advertises size

The size (in bytes) of a tarball Artifact is now advertised in the Size (.size) field of the Artifact. This can be utilized by users to e.g. quickly see if .sourceignore rules have an effect, or be displayed in a UI.

Azure Blob Storage support for Bucket resources

The .spec.provider of a Bucket resource can now be set to azure to instruct the controller to use the Azure Blob Storage SDK while fetching objects. This allows for authenticating using Service Principals, Managed Identities and Shared Keys.

For more information, see the Bucket spec about the Azure provider.

Enhanced Kubernetes Conditions

Source API resources will now advertise more explicit Condition types (more about the types in "API changes"), provide Reconciling and Stalled Conditions where applicable for better integration with kstatus, and record the Observed Generation on the Condition.

For a detailed overview per Source type, refer to the spec:

Enhanced Kubernetes Events (and notifications)

The Kubernetes Events the controller emits have been reworked to provide a proper reason, and more informative messages. Users making use of the notification-controller will notice this as well, as this same information is used to compose notifications.

Experimental managed transport for libgit2 Git implementation

The libgit2 Git implementation supports a new experimental transport to improve reliability, adding timeout enforcement for Git network operations. Opt-in by setting the environment variable EXPERIMENTAL_GIT_TRANSPORT to true in the controller's Deployment. This will result in the low-level transport being handled by the controller, instead of libgit2. It may result in an increased number of timeout messages in the logs, however it will remove the ability of Git operations to make the controllers hang indefinitely.

Reuse of HTTP/S transport for Helm repository index and chart downloads

The Helm dependency has been updated to v3.8.1, with a patch applied from helm/helm#10568. Using this patch, the HTTP transports are now managed by the controller, to prevent the clogging of thousands of open TCP connections on some instances.

Update of libgit2 Git implementation to v1.3.x

The libgit2 Git implementation has been updated to v1.3.x, allowing us to provide better error signals for authentication, certificate and transport failures. Effectively, this means that instead of a unable to clone: User error string, a descriptive one is now given.

In addition, NO_PROXY settings are now properly taken into account.

Preparation of support for rsa-ssh2-256/512

The dependency on golang.org/x/crypto has been updated to v0.0.0-20220315160706-3147a52a75dd, as preparation of support for rsa-ssh2-256/512. This should theoretically work out of the box for known_hosts entries and go-git Git provider credentials, but has not been widely tested.

API changes

The source.toolkit.fluxcd.io/v1beta2 API is backwards compatible with v1beta1.

  • Introduction of Reconciling and Stalled Condition types for better integration with kstatus.
  • Introduction of new Condition types to provide better signals and failure indications:
    • ArtifactOutdated: indicates the current Artifact of the Source is outdated.
    • SourceVerified: indicates the integrity of the Source has been verified.
    • FetchFailed: indicates a transient or persistent fetch failure of the upstream Source.
    • BuildFailed: indicates a transient or persistent build failure of a Source's Artifact.
    • StorageOperationFailed: indicates a transient or persistent failure related to storage.
    • IncludeUnavailable: indicates an include is not available. For example, because it does not exist, or does not have an Artifact.
  • Introduction of a Size (in bytes) field (.status.artifact.size) in the Artifact object.
  • Introduction of ObservedChartName (.status.observedChartName) and ObservedSourceArtifactRevision (.status.observedSourceArtifactRevision) fields in the HelmChart Status.
  • Introduction of azure provider implementation for Bucket.

Updating the manifests in Git to v1beta2 can be done at any time after the source-controller upgrade.

0.21.2

Release date: 2022-02-07

This prerelease changes the default timeout of GitRepositories and Buckets from 20s to 60s. When using the libgit2 Git implementation, increasing the timeout helps avoid Error waiting on socket intermittent SSH cloning failures.

Improvements:

  • Increase default timeout to 60s #570

0.21.1

Release date: 2022-01-27

This prerelease comes with a bug fix to ensure the libgit2 Git implementation respects hostnames with and without port while matching against known_hosts.

Fixes:

  • Fix host mismatch in libgit2 #561

0.21.0

Release date: 2022-01-26

This prerelease comes with changes to the base image used to build and run the controller, replacing Debian Unstable (Sid) with Alpine 3.15. The controller is now statically built and includes libgit2 along with its main dependencies.

The controller container images are signed with Cosign and GitHub OIDC, and a Software Bill of Materials in SPDX format has been published on the release page.

Starting with this version, the controller deployment conforms to the Kubernetes restricted pod security standard:

  • all Linux capabilities were dropped
  • the root filesystem was set to read-only
  • the seccomp profile was set to the runtime default
  • run as non-root was enabled
  • the filesystem group was set to 1337
  • the user and group ID was set to 65534

Breaking changes:

  • The use of new seccomp API requires Kubernetes 1.19.
  • The controller container is now executed under 65534:65534 (userid:groupid). This change may break deployments that hard-coded the user ID of 'controller' in their PodSecurityPolicy.

Improvements:

  • Statically build using musl toolchain and target alpine #558
  • Publish SBOM and sign release artifacts #550
  • security: Drop capabilities, set userid and enable seccomp #521
  • docs: Add git proxy support docs #547
  • libgit2: Configured libgit2 clone ProxyOptions #524
  • storage: include directories in artifact tarball #543
  • Add Permissions to GitHub Workflows #551
  • Update git2go to v31.7.6 #554
  • Update dev docs #555

Fixes:

  • e2e: Set timeout to fix intermittent errors #549
  • git/libgit2: Fix failing tests when the default branch is not "master" #545
  • Remove temp file name from Helm index cache err #540
  • Fix makefile envtest and controller-gen usage #539
  • Update file close operation to not use defer and add test case for CopyFromPath #538
  • Fix the missing protocol for the first port in manager config #556

0.20.1

Release date: 2022-01-07

This prerelease comes with an update for github.com/containerd/containerd to v1.5.9 to please static security analysers and fix any warnings for CVE-2021-43816.

Improvements:

  • Log the error when tmp cleanup fails #533
  • Update containerd to v1.5.9 (fix CVE-2021-43816) #532

0.20.0

Release date: 2022-01-05

This prerelease comes with an update to the Kubernetes and controller-runtime dependencies to align them with the Kubernetes 1.23 release, including an update of Helm to v3.7.2.

In addition, the controller is now built with Go 1.17, and github.com/containerd/containerd was updated to v1.5.8 to please static security analysers and fix any warnings for GHSA-5j5w-g665-5m35.

Improvements:

  • Update Go to v1.17 #473
  • Update build dependencies #520
  • Update containerd to v1.5.8 (fix GHSA-5j5w-g665-5m35) #529

0.19.2

Release date: 2021-12-09

This prerelease ensures the API resources are not prematurely marked as Ready by tools like kstatus, while the controller has not observed a newly created resource yet, by defaulting the ObservedGeneration in the status of the resource to -1.

In addition, it changes the faulty URL column for Bucket resources to Endpoint, and updates github.com/opencontainers/runc to v1.0.3 to please static security analysers and fix any warnings for CVE-2021-43784.

Improvements:

  • crds: set default observedGeneration to -1 #517
  • Update github.com/opencontainers/runc to v1.0.3 (fix CVE-2021-43784) #518

Fixes:

  • Change bucket JSONPath from URL to endpoint #514

0.19.1

Release date: 2021-12-03

This prerelease changes the length of the SHA hex added to the SemVer metadata of a HelmChart, when ReconcileStrategy is set to Revision, to a short SHA hex of the first 12 characters. This is to prevent situations in which the SemVer would exceed the length limit of 63 characters when utilized in a Helm chart as a label value.

Concrete example: 1.2.3+a4303ff0f6fb560ea032f9981c6bd7c7f146d083.1 becomes 1.2.3+a4303ff0f6fb.1

⚠️ There have been additional user reports about charts complaining about a + character in the label:

metadata.labels: Invalid value: "1.2.3+a4303ff0f6fb560ea032f9981c6bd7c7f146d083.1": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue', or 'my_value', or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')

Given the Helm chart best practices mention to replace this character with a _, we encourage you to patch this in your (upstream) chart. Pseudo example using template functions:

{{- replace "+" "_" .Chart.Version | trunc 63 }}

Fixes:

  • controllers: use short SHA in chart SemVer meta #507

0.19.0

Release date: 2021-11-23

For this prerelease we focused on improving the logic around Helm resources, with as goal to be more efficient, and increase code and testing quality.

It contains breaking behavioral changes to HelmRepository and HelmChart resources:

  • Helm repository index files and/or charts must not exceed the new declared runtime default limits to avoid out-of-memory crashes, overwriting the default configuration is possible.

    Type Default max size (in MiB) Option flag to overwrite
    Helm repository index 50MiB --helm-index-max-size=<bytes>
    Helm chart 10MiB --helm-chart-max-size=<bytes>
    Singe file from Helm chart 5MiB --helm-chart-file-max-size=<bytes>

  • Using ValuesFiles in a HelmChart will now append a .<Generation> to the SemVer metadata of the packaged chart and the revision of the Artifact. For example, v1.2.3+.5 for a HelmChart resource with generation 5. This ensures consumers of the chart are able to notice changes to the merged values without the underlying chart source (revision) changing.

While an optional ACL field has been added to the API resources, there is no implementation at time of release.

Improvements:

  • helm: factor out logic from controller into package #485
  • Add ACL option field to Source API #495
  • Update various dependencies to mitigate CVE warning #493
  • Update controller-runtime to v0.10.2 #497
  • Update github.com/minio/minio-go to v7.0.15 #498
  • internal/helm: LoadChartMetadataFromArchive improvements #502
  • internal/helm: validate loaded chart metadata obj #503

Fixes:

  • tests: ensure proper garbage collection #489
  • controllers: Fix helmchart values file merge test #494
  • Update test shield link #496
  • controllers: absolute local path for cached chart #500
  • Various small fixes across the code base #501

0.18.0

Release date: 2021-11-12

This prerelease changes the format of the artifact checksum from SHA1 to SHA256 to mitigate chosen-prefix and length extension attacks.

Improvements:

  • storage: change Artifact checksum to SHA256 #487

0.17.2

Release date: 2021-11-04

This prerelease comes with a bug fix to ensure the libgit2 Git implementation respects the operation timeout specified in GitRepositorySpec.

Fixes:

  • libgit2: ensure context timeout cancels transfer #477

0.17.1

Release date: 2021-10-30

This prerelease fixes a pointer error that was returned in v0.17.0 during the import of public keys to verify a commit.

Fixes:

  • Fix pointer error during public key import #479

0.17.0

Release date: 2021-10-28

For this prerelease we focused on further improving the Git implementations, partly to increase stability and test coverage, partly to ensure they are prepared to be moved out into a separate module. With this work, it is now possible to define just a Git commit as a reference, which will result in an Artifact with a Revision format of HEAD/<commit SHA>.

For the go-git implementation, defining the branch and a commit reference will result in a more efficient shallow clone, and using this information when it is available to you is therefore encouraged.

Improvements:

  • git: refactor authentication, checkout and verification #462

Fixes:

  • libgit2: handle EOF in parseKnownHosts() #475

0.16.1

Release date: 2021-10-22

This prerelease adds support for GCP storage authentication using the GOOGLE_APPLICATION_CREDENTIALS environment variable available in the container, or by defining a secretRef with a serviceaccount JSON data blob. See #434 for more information.

In addition, several bug fixes and improvements have been made to the libgit2 Git implementation, ensuring the checkout logic is more rigorously tested.

During this work, it was discovered that both Git implementation had a minor bug resulting in v prefixed tags with metadata added to it (e.g. v0.1.0+build-1 and v0.1.0+build-2) were not properly sorted by their commit timestamp, which has been addressed as well.

Improvements:

  • Add GCP storage authentication #434

Fixes:

  • libgit2: correctly resolve (annotated) tags #457
  • libgit2: add remaining checkout strategy tests #458
  • git: ensure original tag is used for TS lookup #459

0.16.0

Release date: 2021-10-08

This prerelease improves the configuration of the libgit2 C library, solving most issues around private key formats (e.g. PKCS#8 and ED25519) by ensuring it is linked against OpenSSL and LibSSH2.

In addition, the HelmChart resource does now allow setting a ReconcileStrategy to define when a new artifact for a chart should be created for charts from Bucket and GitRepository sources. By setting this to Revision, you no longer have to bump the version in the Chart.yaml file, but a new chart will automatically be made available when the revision of the Source changes.

Fixes:

  • Update containerd and runc to fix CVEs #446

Improvements:

  • Add reconcile strategy for HelmCharts #308
  • Update github.com/libgit2/git2go to v31.6.1 #437

0.15.4

Release date: 2021-08-05

  • Ensure rel path never traverses outside Storage #417
  • Use same SemVer logic in both Git implementations #417
  • storage: strip env specific data during archive #417

Improvements:

  • e2e: Update Kubernetes to v1.21 #396
  • Update Helm to v3.6.3 #400
  • Add setup-envtest in Makefile #404
  • Use ObjectKeyFromObject instead of ObjectKey #405
  • Drop deprecated io/ioutil #409
  • Update dependencies #416

0.15.3

Release date: 2021-06-29

This prerelease comes with a bug fix to the Git tag checkout when using libgit2.

Fixes:

  • Fix tag checkout with libgit2 #394

0.15.2

Release date: 2021-06-22

This prerelease updates the build constraints for libgit2, ensuring the underlying libssh2-1-dev dependency is linked against libssl-dev instead of libgcrypt so that PKCS* private keys can be used without any issues.

Fixes:

  • Use libgit2 from "unstable" / "sid" #391

0.15.1

Release date: 2021-06-18

This prerelease updates the Helm dependency to v3.6.1, this update is a security update and ensures credentials are only passed to the defined URL in a HelmRelease.

Note: there have been reports from the Helm user community that this new behavior may cause issues with Helm repository providers like Artifactory. If this happens to be a problem for you, the behavior can be disabled by setting PassCredentials in the HelmRepositorySpec.

For more details, see: https://github.com/helm/helm/security/advisories/GHSA-56hp-xqp3-w2jf

Improvements:

  • Update Helm to v3.6.1 #388

0.15.0

Release date: 2021-06-17

This prerelease comes with changes to the base image used to build the controller, replacing Alpine with Debian slim. This change allows the controller to run on ARM64, previously broken in v0.14.0.

Improvements:

  • Use Debian instead of Alpine for multi-arch builds #386
  • Panic on non-nil AddToScheme errors in main init #387

0.14.0

Release date: 2021-06-09

This prerelease comes with an update to the Kubernetes and controller-runtime dependencies to align them with the Kubernetes 1.21 release, including an update of Helm to v3.6.0.

After a failed ARMv7 build during the initial release attempt of this version, binutils-gold has been introduced to the builder image to allow gccgo to build using the Gold linker.

Improvements:

  • Update K8s, controller-runtime and fluxcd/pkg deps #374
  • Add nightly builds workflow #376

Fixes:

  • Reinstate Git cloning timeout #372
  • Use binutils-gold in builder image #377
  • Use github.repository property for image name #378

0.13.2

Release date: 2021-06-02

This prerelease comes with an update to the go-git implementation dependency, bumping the version to v5.4.2. This should resolve any issues with object not found and empty git-upload-pack given errors that were thrown for some Git repositories since 0.13.0.

Fixes:

  • Update go-git to v5.4.2 #370

0.13.1

Release date: 2021-05-28

This prerelease comes with a bug fix to the GitRepository include feature.

Fixes:

  • Fix GitRepository include for nested paths #367

0.13.0

Release date: 2021-05-26

This prerelease comes with support for including the contents of a Git repository into another.

The include feature has multiple benefits over regular Git submodules:

  • Including a GitRepository allows you to use different authentication methods for different repositories.
  • A change in the included repository will trigger an update of the including repository.
  • Multiple GitRepositories could include the same repository, which decreases the amount of cloning done compared to using submodules.

Features:

  • Add include property to GitRepositories #348

Improvements:

  • Update Git packages #365

0.12.2

Release date: 2021-05-10

This prerelease comes with a bug fix to Bucket source ignore handling.

Fixes:

  • Split bucket item key by / to satisfy matcher #356

0.12.1

Release date: 2021-04-23

This prerelease comes with a bug fix to source ignore handling.

Fixes:

  • Configure ignore domain for GitRepository rules #351

0.12.0

Release date: 2021-04-21

This prerelease comes with support for SSH keys with a passphrase.

The .sourceignore files are now loaded by traversing through the directory tree, instead of just looking at the root.

The HelmChart ValueFile string field has been deprecated in favour of ValuesFiles string array.

Features:

  • Support SSH private key with password #338 #339
  • Add ValuesFiles to HelmChart spec #305

Improvements:

  • Check ignore matches before Bucket item downloads #337
  • Add short name for Git and Helm repositories #334
  • Update Helm to v3.5.4 #340

Fixes:

Features:

  • Add support for Git submodules with go-git #327
  • Enable self-signed certs for go-git #324

Improvements:

  • Add well-known CI configs to exclusion list #329

0.10.0

Release date: 2021-03-26

This is the tenth MINOR prerelease.

This prerelease comes with a breaking change to the leader election ID from 305740c0.fluxcd.io to source-controller-leader-election to be more descriptive. This change should not have an impact on most installations, as the default replica count is 1. If you are running a setup with multiple replicas, it is however advised to scale down before upgrading.

The suspended status of resources is now recorded to a gotk_suspend_status Prometheus gauge metric.

Improvements:

  • Record suspend metrics in controllers #311
  • Set leader election deadline to 30s #318
  • Change leader election ID to be more descriptive #319

0.9.1

Release date: 2021-03-15

This prerelease comes with improvements to Git clone errors and patch updates to dependencies.

Improvements:

  • Tidy git clone errors #304
  • Update dependencies #307

0.9.0

Release date: 2021-02-23

This is the ninth MINOR prerelease.

Due to changes in Helm v3.5.2, charts not versioned using strict semver are no longer compatible with source-controller. When using charts from Git, make sure that the version field is set in Chart.yaml.

Improvements:

  • Update dependencies #299
  • Refactor release workflow #300

0.8.1

Release date: 2021-02-18

This prerelease fixes a bug where only one dependency of a Helm chart would be included.

Fixes:

  • Copy loop iterator var for use by goroutine #294

0.8.0

Release date: 2021-02-12

This is the eight MINOR prerelease.

The libgit2 Git implementation now has support for Certificate Authority validation for Git over HTTPS, as well as various bug fixes around working with SSH host key fingerprints.

Alpine has been updated to 3.13, making it possible to move away from edge for libgit2 and musl dependencies.

pprof endpoints have been enabled on the metrics server, making it easier to collect runtime information to for example debug performance issues.

Features:

  • Add custom CA validation for Git over HTTPS #283

Improvements:

  • Rename Git packages to implementations #270
  • Enable pprof endpoints on metrics server #282
  • Add fsGroup to pod security context #285
  • Use musl and libit2 packages from v3.13 branch #289

Fixes:

  • Fix chart with custom valuesFile (0bytes tgz) #286
  • libgit2: use provided host to validate public key #288
  • libgit2: check hostkey type when validating hostkey #290

0.7.4

Release date: 2021-02-03

This prerelease fixes a bug where the controller tried to update dependencies for Helm charts even when dependencies were already present.

0.7.3

Release date: 2021-02-02

This prerelease changes the strategy of the controller's deployment to Recreate to prevent a deadlock during upgrades and to ensure safe usage of backing persistent (RW) volumes.

0.7.2

Release date: 2021-02-01

This prerelease ensures the file server of the controller only starts for the elected leader, and improves the visibility of chart name validation errors.

0.7.1

Release date: 2021-01-25

This prerelease changes the recorded revision for a HelmRepository resource to a SHA1 checksum, this to improve the detection of changes for repositories that do not correctly update their advertised generation timestamp.

0.7.0

Release date: 2021-01-21

This is the seventh MINOR prerelease.

Two new argument flags are introduced to support configuring the QPS (--kube-api-qps) and burst (--kube-api-burst) while communicating with the Kubernetes API server.

The LocalObjectReference from the Kubernetes core has been replaced with our own, making Name a required field. The impact of this should be limited to direct API consumers only, as the field was already required by controller logic.

Overwrite of chart values has been patched to correctly read the data from the defined YAML file.

0.6.3

Release date: 2021-01-19

This prereleases comes with bug fixes to the HelmChart indexes, watches, and the overwrite of chart values.

0.6.2

Release date: 2021-01-16

This prerelease comes with updates to Kubernetes and Helm dependencies. The Kubernetes packages were updated to v1.20.2 and Helm to v3.5.0.

0.6.1

Release date: 2021-01-14

This prerelease fixes a regression bug introduced in v0.6.0 that caused reconciliation request annotations to be ignored in certain scenarios.

0.6.0

Release date: 2021-01-12

This is the sixth MINOR prerelease, upgrading the controller-runtime dependencies to v0.7.0.

The container image for ARMv7 and ARM64 that used to be published separately as source-controller:*-arm64 has been merged with the AMD64 image.

0.5.6

Release date: 2020-12-18

This prerelease fixes a regression bug that made it impossible to reference to a HelmChart.ValuesFile in a path relative to the root of the Bucket or GitRepository source.

0.5.5

Release date: 2020-12-16

This prerelease adds safe guards for user defined relative paths, ensuring they never traverse outside working directories.

Other notable changes:

  • ListObjects V1 fallback for GCS S3 endpoints, ensuring generic Bucket resources connecting to GCS are able to list object
  • HelmChart controller panic regression bug fix, introduced in v0.5.0

0.5.4

Release date: 2020-12-12

This prerelease fixes a bug in the build process that caused the ARMv7 image to fail due to libgit2 requiring musl>=1.2.0.

0.5.3

Release date: 2020-12-11

This prerelease fixes a regression bug causing the commit hash for the go-git implementation to not be forwarded, introduced by the support for multiple Git implementations.

0.5.2

Release date: 2020-12-11

This prerelease adds the option to configure the advertised storage address using the --storage-adv-addr flag.

The default deployment manifest uses this to configure the FQDN of the service (source-controller.$(RUNTIME_NAMESPACE).svc.cluster.local.), but omitting the flag will result in a fallback to the previous behavior for backwards compatibility.

0.5.1

Release date: 2020-12-09

This prerelease fixes a bug in the build process that caused the ARMv7 build to fail due to libgit2 requiring musl>=1.2.0.

0.5.0

Release date: 2020-12-09

This is the fifth MINOR prerelease, adding a new Git implementation (libgit2) to allow for communication with Git servers that just support the Git v2 protocol, like Azure Devops.

The new Git implementation can be enabled by configuring the GitImplementation in a GitRepository to libgit2 (default: go-git). Note that this implementation does not support shallow cloning, and it is therefore advised to only resort to this option if a connection fails with the default configuration.

Other notable changes in this release:

  • Bug fix to respect the configured SSH user in GitRepository URLs
  • Chart name validation for charts from a HelmRepository resource
  • Kubernetes dependency upgrades to v1.19.4
  • Helm upgrade to v3.4.2

0.4.1

Release date: 2020-11-26

This prerelease fixes a bug in the listing of HelmChart resources for GitRepository changes.

0.4.0

Release date: 2020-11-26

This is the fourth MINOR prerelease, adding support for suspension of resources using .spec.suspend, and watchers for the upstream sources of HelmChart resources to detect revision changes faster.

0.3.0

Release date: 2020-11-19

This prerelease comes with a fix to garbage collection. The status sub-resource has a new field called LastHandledReconcileAt that can be used to track the reconciliation progress.

This version comes with a breaking change to the API package: the status condition type is imported from Kubernetes API machinery 1.19.

0.2.2

Release date: 2020-11-12

This prerelease comes with improvements to status reporting. The Kubernetes packages have been updated to v1.19.

0.2.1

Release date: 2020-10-30

This prerelease comes with a fix for a regression bug (introduced in v0.2.0) where dependency entries in the Chart.yaml file during the (re)packaging of the Helm chart artifact would have their names overwritten with the alias if defined.

0.2.0

Release date: 2020-10-29

This is the second MINOR prerelease, it comes with breaking changes:

  • Due to a change of semver library to exclude pre-releases from 1.0.x ranges, support for more complex ranges like >=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1 has been dropped.
  • The histogram metric gotk_reconcile_duration was renamed to gotk_reconcile_duration_seconds

Other notable changes:

  • Ambiguous semver matches are now sorted by the timestamp of the source system to use the most recent match.
  • Added support for downloading dependencies for Helm charts from GitRepository and Bucket sources.
  • Added support for creating artifacts for packaged Helm charts (.tgz) from GitRepository and Bucket sources.
  • The annotation fluxcd.io/reconcileAt was renamed to reconcile.fluxcd.io/requestedAt, the former will be removed in a next release but is backwards compatible for now.

0.1.1

Release date: 2020-10-13

This prerelease comes with Prometheus instrumentation for the controller's resources.

For each kind, the controller exposes a gauge metric to track the Ready condition status, and a histogram with the reconciliation duration in seconds:

  • gotk_reconcile_condition{kind, name, namespace, status, type="Ready"}
  • gotk_reconcile_duration{kind, name, namespace}

0.1.0

Release date: 2020-09-30

This is the first MINOR prerelease, it promotes the source.toolkit.fluxcd.io API to v1beta1 and removes support for v1alpha1.

Going forward, changes to the API will be accompanied by a conversion mechanism. With this release the API becomes more stable, but while in beta phase there are no guarantees about backwards compatibility between beta releases.

0.0.18

Release date: 2020-09-23

This prerelease fixes a reconciliation bug that prevented resources recovering from transient errors. Container images for ARMv7 and ARMv8 are published to ghcr.io/fluxcd/source-controller-arm64. The Helm package was updated to v3.3.4.

0.0.17

Release date: 2020-09-18

This prerelease comes with support for S3 compatible storage sources defined as buckets. The Helm package was updated to v3.3.2.

0.0.16

Release date: 2020-09-12

This prerelease comes with the option to watch for resources in the runtime namespace of the controller or at cluster level.

Liveness and readiness probes have been added to the deployment manifest, and the security has been strengthened by running the controller as a non-root user by default and adding a container security context.

Tests have been added to ensure correct behaviour of the HelmChartReconciler and HelmRepositoryReconciler.
