Highlights

API Changes

This prerelease is only compatible with GitRepository API version v1, first shipped with source-controller v1.0.0-rc.1.

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 image-automation-controller can be deployed multiple times with a unique label selector which is used as the sharding key.

Full Changelog

Improvements:

move controllers to internal/controllers #500
Add reconciler sharding capability based on label selector #504
Update dependencies and GitRepository API to v1 #505
bump google.golang.org/protobuf from 1.29.0 to 1.29.1 #506

In addition, the controller dependencies have been updated to Kubernetes v1.26.1 and controller-runtime v0.14.2. The controller base image has been updated to Alpine 3.17.

Improvements:

build: Enable SBOM and SLSA Provenance #478
Disable caching of Secrets and ConfigMaps #479
Update dependencies #480

0.28.0

Release date: 2022-12-21

This prerelease removes all code references to libgit2 and git2go, from this release onwards the controller will use go-git as the only git implementation. For more information, refer to version 0.27.0's changelog, which started libgit2's deprecation process.

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

Two new feature gates were introduced and are enabled by default:

GitShallowClone: enables the use of shallow clones when pulling source from Git repositories.
GitAllBranchReferences: enables users to toggle the download of all branch head references when push branches are configured.

To opt-out from the feature gates above, start the controller with: --feature-gates=GitShallowClone=false,GitAllBranchReferences=false.

Fixes:

Block the creation of empty commits #470

Improvements:

Add GitShallowClone feature #463
Add feature gate GitAllBranchReferences #469
Remove libgit2 and git2go from codebase #468
build: Link libgit2 via LIB_FUZZING_ENGINE #465
build: Add postbuild script for fuzzing #464
build: Fix cifuzz and improve fuzz tests' reliability #462
Update dependencies #471

0.27.0

Release date: 2022-11-21

This prerelease comes with a major refactoring of the controller's Git operations. The controller can now observe the field spec.gitImplementation instead of always ignoring it and using libgit2. The go-git implementation now supports all Git servers, including Azure DevOps, which previously was only supported by libgit2.

By default, the field spec.gitImplementation is ignored and the reconciliations will use go-git. To opt-out from this behaviour, and get the controller to honour the field spec.gitImplementation, start the controller with: --feature-gates=ForceGoGitImplementation=false.

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.

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.

Starting from this version ImageUpdateAutomation objects with a spec.PushBranch specified will have the push branch refreshed automatically via force push. To opt-out from this behaviour, start the controller with: --feature-gates=GitForcePushBranch=false.

Improvements:

Refactor Git operations and introduce go-git support for Azure DevOps and AWS CodeCommit #451
Add new ForceGoGitImplementation FeatureGate #452
Add support for force push #453
Use Flux Event API v1beta1 #455
Remove deprecated alpha APIs #456
Remove nsswitch.conf creation #458
Update Dependencies #459 #460

0.26.1

Release date: 2022-10-21

This prerelease comes with dependency updates, including the fix for the upstream vulnerability CVE-2022-32149.

In addition, the controller dependencies have been updated to Kubernetes v1.25.3.

Improvements:

Update dependencies #448

0.26.0

Release date: 2022-09-29

This prerelease 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))+$"

Improvements:

api: add custom validation for v1.Duration types #439
Update dependencies #442 #444
Build with Go 1.19 #440
build: Bump CI to macos-11 #441
Fix build by enabling Cosign experimental #438

Improvements:

Align controller logs to Kubernetes structured logging #429
Align output with source-controller on no-ops #431
Refactor Fuzzers based on Go native fuzzing #432
Update dependencies #434

0.24.2

Release date: 2022-08-29

This prerelease comes with a bug fix for when the push branch and reference branch are equal.

In addition, the controller dependencies have been updated to Kubernetes v1.25.0.

Fixes:

Fix fetch error in push branch #423

Improvements:

Update Kubernetes packages to v1.25.0 #425
fuzz: Ensure Go 1.18 for fuzz image #424

0.24.1

Release date: 2022-08-10

This prerelease comes with panic recovery, to protect the controller from crashing when reconciliations lead to a crash.

Improvements:

Enable RecoverPanic #416

0.24.0

Release date: 2022-08-09

This prerelease comes with internal changes that improve the way the controller interacts with Git repositories and some improvement on error messages.

Unmanaged Transport is no longer supported and has now been decommissioned across Flux controllers.

In some instances when Flux is trying to push changes using read-only keys the controller would return an early EOF error message. This has now been changed to early EOF (the SSH key may not have write access to the repository).

Improvements:

Enrich early EOF error message #410
Remove MUSL and enable threadless libgit2 support #411
Decommission libgit2 Unmanaged Transport #412

0.23.5

This prerelease adds a new flag for configuring the SSH host key algorithms and updates the source-controller dependency to v0.25.7, which fixes a deadlock scenario in the SSH managed transport and some SSH connection leak issues.

Improvements:

Update source-controller to v0.25.7 #393
build: enable -race for go test #389
Add new flag --ssh-hostkey-algos #388

0.23.2

0.23.0

Release date: 2022-06-02

This prerelease comes with a new flag --feature-gate to disable/enable 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.

A regression that was introduced in PR #330 which made the controller fail when it tried to push commits to a branch that already existed on remote, has been fixed.

Improvements:

Update dependencies #368
Enable Managed Transport by default #369
Update dependencies #374
Update source-controller with libgit2 race fixes #376

Fixes:

Instruct kyaml/kio to retain sequence indentation style #366

0.22.1

Release date: 2022-05-03

This prerelease comes with dependency updates, including an update of image-reflector-controller to v0.18.0.

Improvements:

Update dependencies #359

Other notable changes:

Rewrite all the tests to testenv with gomega #356

0.22.0

Release date: 2022-04-19

This prerelease comes with further stability improvements in the libgit2 experimental management transport, brings ways to configure Key Exchange Algorithms, plus some extra housekeeping awesomeness.

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

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.

The exponential 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).

Improvements:

Update source controller to improve managed transport #346
Add flags to configure exponential back-off retry #348
Update libgit2 to 1.3.1 #350
Add flag to allow configuration of ssh kex algos #351
Update dependencies #352 #353 #354

0.21.3

Release date: 2022-03-30

This prerelease comes with general stability improvements in the libgit2 experimental management transport and updates various dependencies to their latest versions.

Improvements:

Update dependencies #340

0.21.2

Release date: 2022-03-28

This prerelease improves on the experimental managed transport's 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:

Update source controller to v0.22.4 #337

0.21.1

Release date: 2022-03-23

This prerelease fixes a bug introduced in v0.21.0, where pushes into a branch different from the origin branch would squash all historical commits into one.

In addition, it ensures the API objects fully adhere to newly introduced interfaces, allowing them to work in combination with e.g. the conditions package.

Improvements:

Implement meta.ObjectWithConditions interfaces #328
Update image-reflector-controller API to v0.17.1 #331
Update source-controller to v0.22.2 #333

Fixes:

Fix bug when pushing into different branch #330

0.21.0

Release date: 2022-03-22

This prerelease further improves Git operations' stability, upgrades source controller to v0.22 and prepares the code base for more standardized controller runtime operations.

The source-controller dependency was updated to version v0.22 which introduces API v1beta2. This requires the source-controller running in the same cluster to be v0.22.0 or greater.

Git operations using go-git have been migrated away to git2go, which is now the only framework this controller uses for interacting with repositories.

A new experimental transport has been added 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 resolve the bug in which Git operations can make the controllers hang indefinitely.

Improvements:

Update libgit2 to 1.3.0 #321
Remove direct dependency to go-git #324
Update pkg/runtime and apis/meta #325
Add experimental managed transport for libgit2 operations #326

Fixes:

Update libgit2 to 1.3.0 #320
Consolidate use of libgit2 for git operations #323
unable to clone: Certificate #298
Controller stops reconciling, needs restart #282
image-automation-controller not reconnecting after operation timed out #209

0.20.1

Release date: 2022-03-01

This prerelease comes with improvements to the libgit2 OpenSSL build dependency, which fixes some issues related to git server connection leaks.

In addition, github.com/prometheus/client_golang was updated to v1.11.1 to please static analysers and fix warnings for CVE-2022-21698.

Improvements:

Upgrade libgit2 and fix static builds #311
Add support for fuzzing tests using oss-fuzz-build. #314
Add support for multiple fuzz sanitizers #317
Update dependencies (fix CVE-2022-21698) #319

0.20.0

Release date: 2022-02-01

This prerelease comes with support for referencing GitRepositories from another namespace using the spec.sourceRef.namespace field in ImageUpdateAutomations.

Platform admins can disable cross-namespace references with the --no-cross-namespace-refs=true flag. When this flag is set, automations can only refer to Git repositories in the same namespace as the automation object, preventing tenants from accessing another tenant's repositories.

The controller is now statically built and includes libgit2 along with its main dependencies. The base image used to build and run the controller, was changed from Debian Unstable (Sid) to Alpine 3.15.

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 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.

Features:

Add support for cross-namespace sourceRef in ImageUpdateAutomation #299
Allow disabling cross-namespace references #305

Improvements:

Publish SBOM and sign release artifacts #302
Drop capabilities, enable seccomp and enforce runAsNonRoot #295
Statically build using musl toolchain and target alpine #303

0.19.0

Release date: 2022-01-07

This prerelease comes with an update to the Kubernetes and controller-runtime dependencies to align them with the Kubernetes 1.23 release.

In addition, the controller is now built with Go 1.17.

Improvements:

Update Go to v1.17 #248
Log the error when removing the working dir fails #287

Fixes:

Fix potentially broken support for macOS #278
Move Path check into switch case #284

0.18.0

Release date: 2021-11-23

This prerelease updates several dependencies to their latest version, solving an issue with rest_client_request_latency_seconds_.* high cardinality metrics.

Improvements:

Update controller-runtime to v0.10.2 #268
Update image-reflector-controller and source-controller #269

Fixes:

Remove deprecated io/ioutil #267

0.17.1

Release date: 2021-11-11

This prerelease comes with a bug fix to the image setter, ensuring it does not accidentally replace a valid image reference with an invalid one.

Fixes:

Replace strings.TrimRight with strings.TrimSuffix #262

0.17.0

Release date: 2021-11-09

This prerelease comes with improvements to alerting. The controller no longer emits events when no updates were made to the upstream Git repository. After a successful Git push, the controller emits an event that contains the commit message.

Improvements:

Add the commit message to the event body #259

Fixes:

Fix unhandled error in signing key retrieval #258
Use strings.TrimRight to determine image name #257

0.16.1

Release date: 2021-11-04

This prerelease adds more improvements around the libgit2 C library used for Git transport operations, ensuring they respect the operation timeout specified in GitRepositorySpec of the respective GitRepository referenced in GitCheckoutSpec.

Improvements:

Respect PKG_CONFIG_PATH from the environment #251
Pass context to libgit2.RemoteCallbacks #252

0.16.0

Release date: 2021-10-28

This prerelease finalizes the improvements around the libgit2 C library. Users who noticed a memory increase after upgrading to v0.15.0 are highly encouraged to update to this new version as soon as possible, as this release stabilizes it again.

In addition, support for sprig functions has been added in this release; allowing for more complex manipulations and transformations of the commit message.

Improvements:

Add support for the sprig functions library #223
controllers: use new git contract #239

0.15.0

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.

Improvements:

Update github.com/libgit2/git2go to v31.6.1 #222
Use pkg/runtime consts for log levels #232
Update fluxcd/image-reflector-controller to v0.12.0 #233

Fixes:

Provide a sample of v1beta1 ImageUpdateAutomation #219
Fix nil-dereference in controller #224

0.14.1

Release date: 2021-08-05

This prerelease comes with an update to the Kubernetes and controller-runtime dependencies to align them with the Kubernetes 1.21.3 release.

Improvements:

Update dependencies #211
Fail push if a ref update is rejected #195

0.14.0

Release date: 2021-06-28

This prerelease promotes the API version from v1alpha2 to v1beta1.

⚠️ If you have migrated your YAML files from v1alpha1 to v1alpha2, no action is necessary at present since Kubernetes will automatically convert between v1alpha2 and v1beta1.

You may wish to migrate YAML files to v1beta1 to prepare for v1alpha2 being deprecated eventually. This is simply a case of replacing the apiVersion field value:

apiVersion: image.toolkit.fluxcd.io/v1beta1

Instructions for migrating from v1alpha1 are included in the API guide.

Improvements:

Let people set the number of controller workers with a flag #192
Output trace information to the debug log #190

0.13.0

Release date: 2021-06-22

This prerelease comes with changes to the base image used to build the controller, replacing Alpine with Debian slim.

Improvements:

Use Debian as base image #187

0.12.0

Release date: 2021-06-10

This prerelease comes with an update to the Kubernetes and controller-runtime dependencies to align them with the Kubernetes 1.21 release, and an update to the YAML packages (used by the controller to patch Kubernetes manifests) to fix long-standing issues like panics on YAML with non-ASCII characters.

This update to gopkg.in/yaml.v3 means that the indentation style changed:

From:

spec:
  containers:
  - name: one
    image: image1:v1.0.0 # {"$imagepolicy": "automation-ns:policy1"}
  - name: two
    image: image2:v1.0.0 # {"$imagepolicy": "automation-ns:policy2"}

To:

spec:
  containers:
    - name: one
      image: image1:v1.0.0 # {"$imagepolicy": "automation-ns:policy1"}
    - name: two
      image: image2:v1.0.0 # {"$imagepolicy": "automation-ns:policy2"}

Improvements:

Update go-yaml with changes to indentation style #182
Add nightly builds workflow and allow RC releases #184
Update dependencies #183

0.11.0

Release date: 2021-06-02

This prerelease replaces go-git usage with libgit2 for clone, fetch and push operations.

The gitImplementation field in the referenced GitRepository is ignored. The automation controller cannot use shallow clones or submodules, so there is no reason to use the go-git implementation rather than libgit2.

Improvements:

Use libgit2 for clone, fetch, push #177

0.10.1

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 0.10.0.

Fixes:

Update go-git to v5.4.2 #174

0.10.0

Release date: 2021-05-26

This prerelease updates the source-controller dependencies to v0.13.0 to include changes to Git and OpenPGP related dependencies.

Improvements:

Update source-controller to v0.13.0 #169
Switch to github.com/ProtonMail/go-crypto/openpgp #169
Update source-controller/api to v0.13.0 #170

0.9.1

Release date: 2021-05-06

This prerelease comes with a fix to the image name setter.

Fixes:

Fix image name marker #162
spec: fix formatting v1alpha1 -> v1alpha2 table #156

0.9.0

Release date: 2021-04-22

This prerelease deprecates the v1alpha1 API declarations in favor of the new v1alpha2 API. The steps required to rewrite your v1alpha1 objects to v1alpha2 have been documented in the v1alpha2 spec.

Improvements:

Add v1alpha2 API version #139
Move to ImagePolicy v1alpha2 #153
Update source-controller/api to v0.12.0 #154

0.8.0

Release date: 2021-04-06

This prerelease adds support for signing commits with GPG.

This prerelease comes with a breaking change to the leader election ID from e189b2df.fluxcd.io to image-reflector-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 controller exposes a gauge metric to track the suspended status of ImageUpdateAutomation objects: gotk_suspend_status{kind,name,namespace}.

Features:

Enable GPG Signing of Commits #136

Improvements:

Record suspension metrics #129
Update ImageUpdateAutomation Status with Patch #132

0.7.0

Release date: 2021-03-17

This prerelease comes with support for restricting the image updates to a path relative to the Git repository root with .spec.update.path.

The controller can push changes to a different branch than the one used for cloning when configured with .spec.push.branch.

The commit message template supports listing the images that were updated along with the resource kind and name e.g.:

spec:
  commit:
    messageTemplate: |
      Automated image update
      
      Automation name: {{ .AutomationObject }}
      
      Files:
      {{ range $filename, $_ := .Updated.Files -}}
      - {{ $filename }}
      {{ end -}}
      
      Objects:
      {{ range $resource, $_ := .Updated.Objects -}}
      - {{ $resource.Kind }} {{ $resource.Name }}
      {{ end -}}
      
      Images:
      {{ range .Updated.Images -}}
      - {{.}}
      {{ end -}}

Features:

Allow specifying the path for manifests updates #126
Push to branch #121
Supply update result value to the commit message template #119

Improvements:

Update runtime dependencies #124

0.6.1

Release date: 2021-02-25

This prerelease improves the formatting of error messages returned when a git push to an upstream Git repository fails.

Improvements:

Better error messages from git push #115

0.6.0

Release date: 2021-02-24

This prerelease comes with various updates to the controller's dependencies.

The Kubernetes custom resource definitions are packaged as a multi-doc YAML asset and published on the GitHub release page.

Improvements:

Refactor release workflow #112
Update dependencies #111

0.5.0

Release date: 2021-02-12

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.

A bug has been fixed that caused SSH authentication for the libgit2 Git implementation to fail.

Improvements:

Enable pprof endpoints on metrics server #104
Update Alpine to v3.13 #105
Use musl and libgit2 packages from v3.13 branch #107
Update kyaml to v0.10.9 #108

Fixes:

Test git over SSH too, and correct hard-wired implementation causing SSH/libgit2 problems #109

0.4.0

Release date: 2021-01-22

This prerelease reforms the update strategy types API in a backwards compatible manner.

In addition, it comes with two new argument flags 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 the 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.

Improvements:

Update fluxcd/pkg/runtime to v0.8.0 #98
Reform update strategy types #95
Add API reference for ImageUpdateAutomation #94

0.3.1

Release date: 2021-01-18

This prerelease comes with updates to Kubernetes and Kustomize dependencies. The Kubernetes packages were updated to v1.20.2 and kyaml to v0.10.6.

0.3.0

Release date: 2021-01-15

This prerelease adds support for the libgit2 implementation, making it possible to push changes to Git servers that require support for the v2 protocol, like Azure DevOps.

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

Improvements:

Update to kyaml 0.10.5 #87
Upgrade controller-runtime to v0.7.0 #84
Libgit2 support #82
Publish as single multi-arch Docker image #80

0.2.0

Release date: 2021-01-06

This prerelease comes with a fix to the manifest update mechanism. The controller now only writes files that were actually updated by an image policy setter instead of reformatting all Kubernetes YAMLs.

Starting with this version, the spec.checkout.branch field is mandatory.

Fixes:

Screen files, and output only those updated #73

Improvements:

Record last pushed commit in status #75
Make the branch field mandatory #74

0.1.0

Release date: 2020-12-10

This is the first prerelease of image-automation-controller and its API. The controller watches ImagePolicy objects (as in the [image-reflector-controller API][imagev1]) and commits updates to files in git when the "latest image" changes.

The controller and API conform to the GitOps Toolkit conventions, and will work with the flux CLI, and dashboards using the standard metrics, and so on.

This release supports:

updating YAML files with image refs, names or tags according to markers you add in the YAML.
supplying a custom commit message
