Release date: 2023-03-31
This prerelease adds support for Azure Workload Identity when using
provider: azure in ImageRepository objects.
In addition, the controller now supports horizontal scaling using sharding based on a label selector.
The new --watch-label-selector lets operators provide a label to the controller manager
which in turn uses it to reconcile only those resources
(ImageRepositories and ImagePolicies) that match the given label expression.
This way operators can deploy multiple instances of IRC, each reconciling a distinct set of resources based on their labels and effectively scale the controller horizontally.
If sharding is enabled, all ImagePolicy resources can only refer
to those ImageRepository resources that are captured by the exact
same label selector as the ImagePolicies.
Improvements:
- Add reconciler sharding capability based on label selector #365
- Enable Workload Identity for Azure #363
- Move
controllerstointernal/controllers#362
Release date: 2023-03-20
This prerelease fixes a bug in the reconcilers due to which an error log due to some failure may contain previous successful reconciliation message.
Fixes:
- Fix error logs with stale success message #357
Improvements:
- chore: migrate from k8s.gcr.io to registry.k8s.io #358
Release date: 2023-03-08
This prerelease re-instantiates the --aws-autologin-for-ecr,
--gcp-autologin-for-gcr and --azure-autologin-for-acr flags which became
deprecated in v0.25.0, after receiving feedback of it complicating
upgrading gradually. The flags will now be removed in the future, and at least
one minor version after this release. We are sorry for any inconvenience this
may have caused.
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 with Go 1.20, and the dependencies have been updated to their latest versions.
Improvements:
- Update Go to 1.20 #347
- Update dependencies #349 #351
- Use
logger.SetLoggerto also configureklog#350 - Fallback to autologin flags if no provider is specified #353
Release date: 2023-02-16
This prerelease graduates the ImageRepository and ImagePolicy APIs to
v1beta2.
After upgrading the controller to v0.25.0, please update the ImageRepository
and ImagePolicy Custom Resources in Git by replacing
image.toolkit.fluxcd.io/v1beta1 with image.toolkit.fluxcd.io/v1beta2 in all
YAML manifests.
The 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.
ImageRepository and ImagePolicy resources will now advertise more explicit
Condition types, provide Reconciling and Stalled Conditions where applicable
for better integration with
kstatus,
and record the Observed Generation on the Condition.
The ImageRepository objects will now show the ten latest scanned tags, which
can be helpful in troubleshooting to see a sample of the tags that have been
scanned.

The autologin flags (--aws-autologin-for-ecr, --gcp-autologin-for-gcr and
--azure-autologin-for-acr) have been deprecated to bring the Image API closer
to the Source API, where cloud provider contextual login is configured at object
level with .spec.provider. Usage of these flags will result in a logged error.
Please update all the ImageRepository manifests that require contextual login
with the new field .spec.provider and the appropriate cloud provider value;
aws, gcp, or azure. Refer the
docs for
more details and examples.
Improvements:
Release date: 2023-02-01

Improvements:
- Update dependencies #319
Release date: 2022-09-27
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.
ImageRepository.spec.intervalnew validation pattern is"^([0-9]+(\\.[0-9]+)?(ms|s|m|h))+$"ImageRepository.spec.timeoutnew validation pattern is"^([0-9]+(\\.[0-9]+)?(ms|s|m))+$"

In addition, the controller dependencies where update to Kubernetes v1.24.1.
Improvements:
Release date: 2022-05-27
This prerelease adds support for excluding certain tags when defining ImageRepositories.
The spec.exclusionList field can be used to specify a list of regex expressions.
If the exclusion list is empty, by default the regex "^.*\\.sig$" is used
to exclude all tags ending with .sig, since these are
cosign OCI artifacts and not container
images which can be deployed on a Kubernetes cluster.
Features:
- Add
exclusionListto ImageRepository API #256
Improvements:
Release date: 2022-05-03

This prerelease comes with support for automatically getting credentials from Azure and Google Cloud when scanning images in ACR and GCR. To configure autologin for ACR, ECR or GCR please see the cloud providers authentication guide.
Platform admins can disable cross-namespace references with the
--no-cross-namespace-refs=true flag. When this flag is set,
image policies can only refer to image repositories in the same namespace
as the policy object, preventing tenants from accessing another tenant's repositories.
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:
- Get credentials from GCP/Azure when needed #194
- Allow disabling cross-namespace references to image repositories #228
Improvements:
- Publish SBOM and sign release artifacts #227
- Drop capabilities, enable seccomp and enforce runAsNonRoot #223
- Refactor Fuzz implementation #221

In addition, the controller is now built with Go 1.17 and Alpine 3.15.
Improvements:
Release date: 2021-11-23
This prerelease updates Alpine to v3.14, and several dependencies to their latest
version. Solving an issue with rest_client_request_latency_seconds_.* high
cardinality metrics.
To enhance the experience of consumers observing the ImagePolicy and ImageRepository
objects using kstatus, a default of -1 is now configured for the observedGeneration
to ensure it does not report a false positive in the time the controller has not marked
the resource with a Ready condition yet.
Improvements:
- Set default observedGeneration to -1 #189
- Update Alpine to v3.14 #203
- Update dependencies #204
- Update github.com/opencontainers/image-spec to v1.0.2 #205

access to ImageRepository resources. You can read more about how they work in the
pull request that
introduced them.
In addition, a bug has been fixed that caused the controller to segfault when a malformed SemVer was defined.
Improvements:
- [RFC] Add ACL support for allowing cross-namespace access to image repository #162
Fixes:
- policy: Handle failure due to invalid semver range #172
Release date: 2021-08-05

This prerelease promotes the API version from v1alpha2 to v1beta1.
v1alpha2
and v1beta1 APIs.
You may wish to migrate v1alpha2 YAML files to v1beta1, in
preparation for v1alpha2 being deprecated (eventually; there is no
date set at the time of writing). This is simply a case of setting the
apiVersion field value:
`apiVersion: image.toolkit.fluxcd.io/v1beta1`
Improvements:
- Let people set the number of controller workers with a flag #153
Release date: 2021-06-10

This prerelease comes with breaking changes to the image.toolkit.fluxcd.io APIs.
The v1alpha1 APIs have been promoted to v1alpha2, while the version has
changed the API definitions have not, and upgrading can be done by changing
the version in your manifests for the ImageRepository and ImagePolicy kinds.
Improvements:
Fixes:
- Parse docker auths and use only hostname #119
Release date: 2021-04-06
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 ImageRepository objects: gotk_suspend_status{kind,name,namespace}.
Improvements:
- Set leader election deadline to 30s #125
- Record suspension metrics #123
Release date: 2021-03-16
This prerelease comes with updates to the runtime packages.

Release date: 2021-01-22
This prerelease comes with a new argument flag to set the database's
memory mapped value log file size in bytes (--storage-value-log-file-size),
with a 32bit ARMv7 friendly default of 1<<28 (256MiB).
Release date: 2021-01-21
This prerelease 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.
Release date: 2021-01-16
This prerelease comes with updates to Kubernetes and Badger dependencies. The Kubernetes packages were updated to v1.20.2 and Badger to v3.2011.0.
Release date: 2021-01-13
This is the second MINOR prerelease, adding support for selecting images using regular expressions.
Other notable changes:
controller-runtimedependency has been upgraded tov0.7.0.- The container image for ARMv7 and ARM64 that used to be published
separately as
image-reflector-controller:*-arm64has been merged with the AMD64 image.
Release date: 2020-12-10
This is the first prerelease of image-reflector-controller and its API. The purpose of the controller is to scan image repositories, and calculate a "latest image" according to some specification. Automation (e.g., the image-automation-controller) can use that information to run updates, so that the latest image is deployed.
The controller and API conform to the conventions of the GitOps
Toolkit, so will be compatible with (and soon, included in) the flux
CLI and dashboards and so on.
This release supports:
- supplying a docker-registry secret as credentials for accessing an image repository
- selecting images according to a semver range.
- selecting images according to alphabetical order (ascending or descending)
- keeping the database on a volume (e.g., a PersistentVolumeClaim) so that it survives restarts
