Breaking changes

Deprecation of gitImplementation

The interpretation of the gitImplementation field of GitRepository by source-controller and image-automation-controller has been deprecated, and will effectively always use go-git. This now supports all Git servers, including Azure DevOps and AWS CodeCommit, which previously were only supported by libgit2.

To opt-out from this behaviour, and get the controller to honour the field .spec.gitImplementation, start the controller with: --feature-gates=ForceGoGitImplementation=false.

For more information on this change, refer to the controllers's respective changelogs listed below.

Automatic force-push of ImageUpdateAutomation

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.

Features and improvements

• Support for bootstrapping Azure DevOps and AWS CodeCommit repositories using flux bootstrap git.
• Support cloning of Git v2 protocol (Azure DevOps and AWS CodeCommit) for go-git Git provider.
• Support force-pushing ImageUpdateAutomation repositories.
• Allow a dry-run of flux build kustomization with --dry-run and --kustomization-file ./path/to/local/my-app.yaml. Using these flags, variable substitutions from Secrets and ConfigMaps are skipped, and no connection to the cluster is made.
• Use signed OCI Helm chart for kube-prometheus-stack.
