Changelog

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
  • Set leader election deadline to 30s #137
  • Update kyaml to v0.10.16 #141

Fixes:

  • Ensure that an unchanged image is not in update result #144
  • Fix problem with pushing further commits to a "push branch" #143
  • Ignore broken symlinks and outside path, in commit #142

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
