Highlights

Flux v2.9.4 is a patch release that ships various fixes to the Flux controllers, covering source-watcher tarball extraction and glob expansion limits, the refspecs accepted by ImageUpdateAutomation, the HTTP request limits of the notification-controller servers, and Helm repository index loading, OCI chart digest pinning, Bucket error handling and GCS static authentication in source-controller. On the CLI side, flux migrate -f now supports migrating repositories to Flux 2.9. Users are encouraged to upgrade for the best experience.

Note that this release contains CRD schema changes for ArtifactGenerator and ImageUpdateAutomation; both CRDs must be updated along with the controllers.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Confine tarball extraction and bound glob expansion (source-watcher)
• Disallow force-update and deletion via refspecs (image-automation-controller)
• Unify HTTP server request limits (notification-controller)
• Align Helm repository index loading with upstream Helm v4 (source-controller)
• Improve error handling in Bucket reconciliation (source-controller)
• Pin OCI chart verification by digest (source-controller)
• Limit GCS static authentication to service account keys (source-controller)
• Restrict the allow-webhooks network policy to the receiver port (flux CLI)

Improvements:

• Add support for migrating repositories to 2.9 in flux migrate -f (flux CLI)
• Update fluxcd/pkg dependencies, which align the ECR host detection with upstream (source-controller, image-reflector-controller, flux CLI)
• Update Bitbucket Cloud receiver guidance (notification-controller)

v2.9.3

Compare Source

Highlights

Flux v2.9.3 is a patch release. It fixes empty lines vanishing from rendered Helm chart manifests, HelmReleases being marked as tested when their Helm test hooks never ran, and spec.images entries that set only some image fields discarding the remaining fields already declared for the same image in the kustomization.yaml. The latter affects both kustomize-controller and the flux build|diff kustomization commands. Users are encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Fix empty lines vanishing from rendered chart manifests (helm-controller)
• Fix HasBeenTested for all corner cases, where a release could be marked as tested although its Helm test hooks never ran (helm-controller)
• Fix a spec.images entry setting only some of the image fields discarding the remaining fields already declared for the same image in the kustomization.yaml at spec.path, e.g. overriding only newName produced an untagged image reference (kustomize-controller, flux CLI)

Improvements:

• Update fluxcd/pkg dependencies
• Include source-watcher in the OCI flux-manifests artifact

Components changelog

• kustomize-controller v1.9.4
• helm-controller v1.6.3

CLI changelog

• [release/v2.9.x] Include source-watcher to oci flux-manifests by @​fluxcdbot in #​5996

• Update toolkit components by @​fluxcdbot in #​6011

v2.9.2

Compare Source

Highlights

Flux v2.9.2 is a patch release. The main fix addresses a regression introduced in
v2.9.1 where a Kustomization with openapi.path pointing to a URL failed to
reconcile with failed to read OpenAPI schema. This release also corrects several
CRD field descriptions that contained inaccurate or leaked content. Users are
encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Fix a regression where a Kustomization with openapi.path pointing to a URL failed to reconcile with failed to read OpenAPI schema (kustomize-controller)
• Fix the HelmChart CRD description for .status.url, which pointed users at BucketStatus.Artifact instead of HelmChartStatus.Artifact (source-controller)
• Fix the ImageRepository CRD description for .status.observedExclusionList, which referred to spec.lastScanResult instead of status.lastScanResult (image-reflector-controller)
• Fix the ImageUpdateAutomation CRD description for .status.observedSourceRevision, which had a stray Go struct declaration leaking into it (image-automation-controller)

Improvements:

• Update fluxcd/pkg dependencies

Components changelog

• source-controller v1.9.3
• kustomize-controller v1.9.3
• helm-controller v1.6.2

Kubernetes compatibility

This release is compatible with the following Kubernetes versions:

Kubernetes version	Minimum required
v1.34	>= 1.34.1
v1.35	>= 1.35.0
v1.36	>= 1.36.0

[!NOTE]
Note that the Flux project offers support only for the latest three minor versions of Kubernetes.
Backwards compatibility with older versions of Kubernetes and OpenShift is offered by vendors such as
ControlPlane that provide enterprise support for Flux.

OpenShift compatibility

Flux can be installed on Red Hat OpenShift cluster directly from OperatorHub using Flux Operator. The operator allows the configuration of Flux multi-tenancy lockdown, network policies, persistent storage, sharding, vertical scaling and the synchronization of the cluster state from Git repositories, OCI artifacts, and S3-compatible storage.
