v2.0.0-rc.3

Highlights

This is the 3rd release candidate of Flux v2.0 GA. Users are advised to upgrade from v0.41 and older versions to v2.0.0-rc.3 as soon as possible.

Flux v2.0.0-rc.3 comes with security improvements, new features and fixes to issues reported for RC.2.

💡 For upgrading from v0.x, please see the procedure documented in RC.1.

⚠️ Note that Kubernetes 1.27.0 contains a regression bug that affects Flux, it is recommended to upgrade Kubernetes to 1.27.1 or newer.

Fixes and improvements

  • Fix bootstrap on GKE (RC.2 regression due to insufficient quota for critical pods).
  • All controller base images have been updated to Alpine 3.18.
  • All components have been updated to patch CVE-2023-2253 and CVE-2023-1732 (note that Flux is not affected, these CVEs are for packages used in tests).
  • Verify artifacts integrity, issue warning events and remove tempered artifacts from storage forcing a re-download (source-controller).
  • Files with executable permissions are now archived with their mode set to 0o744, allowing CI system to run them (source-controller).
  • The Alert v1beta2 API has a new optional field .spec.eventMetadata that allows users to enrich the alerts with information about the cluster name, region, environment, etc. (notification-controller).
  • Improve the detection of values changes for HelmReleases by stable sorting them by key (helm-controller).

v2.0.0-rc.2

Highlights

This is the 2nd release candidate of Flux v2.0 GA. Users are advised to upgrade from v0.41 to v2.0.0-rc.2 as soon as possible.

Flux v2.0.0-rc.2 comes with fixes to issues reported for RC.1 and performance improvements. Starting with this version, source-controller, kustomize-controller and helm-controller pods are marked as system-cluster-critical. This priority class will reduce the chances of Flux controllers being evicted before other non-critical workloads and prevents the pods from being permanently unavailable.

💡 For upgrading from v0.x, please see the procedure documented in RC.1.

⚠️ Note that Kubernetes 1.27.0 contains a regression bug that affects Flux, it is recommended to upgrade Kubernetes to 1.27.1 or newer.

Fixes and improvements

  • Fix bootstrap for BitBucket Server (CLI).
  • Fix secrets decryption when using Azure Key Vault (kustomize-controller).
  • Fix drift detection for renamed HelmReleases (helm-controller).
  • Improve performance when handling webhook receivers (notification-controller).
  • The Alert v1beta2 API has a new optional field .spec.inclusionList for fine-grained control over events filtering (notification-controller).
  • The deprecated field .status.url was removed from the Receiver v1 API (notification-controller).
  • Add support for commit signing using OpenPGP keys with passphrases (image-automation-controller).

v2.0.0-rc.1

Highlights

This is the first release candidate of Flux v2.0 GA 🎉. Users are encouraged to upgrade for the best experience.

Flux v2.0.0-rc.1 comes with the promotion of the GitOps related APIs to v1 and adds horizontal scaling & sharding capabilities to Flux controllers.

In addition, RC.1 comes with support for auth with Azure Workload Identity when pulling OCI artifacts from ACR and when decrypting secret with Azure Vault. Also, Bootstrap for GitLab was extended with support for generating GitLab Deploy Tokens.

❤️ Big thanks to all the Flux contributors that helped us with this release!
👏 And a special shoutout to the GitLab team for their first contribution to Flux!

API changes

GitRepository v1

The GitRepository kind was promoted from v1beta2 to v1 (GA) and deprecated fields were removed.

The v1 API is backwards compatible with v1beta2, except for the following:

  • the deprecated field .spec.gitImplementation was removed
  • the unused field .spec.accessFrom was removed
  • the deprecated field .status.contentConfigChecksum was removed
  • the deprecated field .status.artifact.checksum was removed
  • the .status.url was removed in favor of the absolute .status.artifact.url

Kustomization v1

The Kustomization kind was promoted from v1beta2 to v1 (GA) and deprecated fields were removed.

A new optional field .spec.commonMetadata was added to the API for setting labels and/or annotations to all resources part of a Kustomization.

The v1 API is backwards compatible with v1beta2, except for the following:

  • the deprecated field .spec.validation was removed
  • the deprecated field .spec.patchesStrategicMerge was removed (replaced by .spec.patches)
  • the deprecated field .spec.patchesJson6902 was removed (replaced by .spec.patches)

Receiver v1

The Receiver kind was promoted from v1beta2 to v1 (GA).

The v1 API now supports triggering the reconciliation of multiple resources using .spec.resources.matchLabels.

The v1 API is backwards compatible with v1beta2, no fields were removed.

Upgrade procedure

Upgrade Flux from v0.x to v2.0.0-rc-1 either by rerunning flux bootstrap or by using the Flux GitHub Action.

To upgrade the APIs from v1beta2, after deploying the new CRDs and controllers, change the manifests in Git:

  1. Remove the deprecated fields from the GitRepository and Kustomization definitions.
  2. Commit, push and reconcile the fields removal changes.
  3. Set apiVersion: source.toolkit.fluxcd.io/v1 in the YAML files that contain GitRepository .
  4. Set apiVersion: kustomize.toolkit.fluxcd.io/v1 in the YAML files that contain Kustomization .
  5. Set apiVersion: notification.toolkit.fluxcd.io/v1 in the YAML files that contain Receiver definitions.
  6. Commit, push and reconcile the API version changes.

Bumping the APIs version in manifests can be done gradually. It is advised to not delay this procedure as the beta
versions will be removed after 6 months.

⚠️ Note that this release updates the major version of the Flux Go Module to v2. Please update your go.mod to require github.com/fluxcd/flux2/v2, see pkg.go.dev for the documentation of the module.

v0.41.0

Flux v0.41.0 comes with new features and improvements. Users are encouraged to upgrade for the best experience.

Features and improvements

  • Experimental support of drift detection of Helm releases compared to cluster-state.
  • Improved handling of SIGTERM signals received by the helm-controller, which will now terminate running Helm install or upgrade actions, instead of potentially leaving them in a pending state.
  • Opt-in OOM watcher in helm-controller to handle graceful termination of the controller before it is forcefully killed by Kubernetes' OOM killer.
  • Kubernetes client and Custom Resource Definition life-cycle improvements to reduce the memory consumption of the helm-controller, with observed reductions up to 50%.
  • Opt-in allowance of DNS lookups during the rendering of Helm templates in the helm-controller via feature gate.
  • Optional disabling of the cache of the status poller used to determine the health of the resources applied by the kustomize-controller. This may improve memory usage on large scale clusters at the cost of more direct API calls.
  • Changes to the logging of all controllers to ensure Kubernetes components like the discovery client use the configured logging format.
  • New flux events command to display Kubernetes events for Flux resources, including the events of a referenced resource.
  • Custom annotations can now be set with flux push using --annotations.

Breaking changes

Image Automation

The image-reflector-controller autologin flags have been deprecated and are no longer used.
Please see the new API specification and migration instructions in the controller changelog.

Notifications

The source revision format reported by the Flux controllers has changed according to RFC-0005.
The events referring to Git repositories, will report the revision in the format <branch|tag>@sha1:<commit> instead of <branch|tag>/<commit>.
For more details please see the source-controller changelog.

OCI artifacts

The OCI artifacts produced with flux push artifact have now custom media types:

  • artifact media type application/vnd.oci.image.manifest.v1+json
  • config media type application/vnd.cncf.flux.config.v1+json
  • content media type application/vnd.cncf.flux.content.v1.tar+gzip

Features and improvements

  • The GitRepository API has a new optional field .spec.ref.name for specifying a Git Reference.
    This allows Flux to reconcile resources from GitHub Pull Requests (refs/pull/<id>/head) and GitLab Merge Requests (refs/merge-requests/<id>/head).
  • The ImageRepository and ImagePolicy APIs have been promoted to v1beta2.
  • Allow specifying the cloud provider contextual login for container registries with ImageRepository.spec.provider.
  • Improve observability of ImageRepository by showing the latest scanned tags under .status.lastScanResult.latestTags.
  • Improve observability of ImagePolicy by reporting the current and previous image tag in status and events.
  • The Kubernetes builtin cluster roles: view, edit and admin have been extended to allow access to Flux custom resources.
  • Print a report of Flux custom resources and the amount of cumulative storage used for each source type with flux stats -A.

v0.39.0

Highlights

Flux v0.39.0 comes with new features and improvements. Users are encouraged to upgrade for the best experience.

Starting with this version, the Flux controllers come with SBOMs and SLSA Provenance Attestations embedded in their container images.

The Flux Terraform Provider has a new resource for bootstrapping Flux, without depending on third-party Terraform providers, that allows customising the controllers at install time. Users are encouraged to migrate to this new resources and provide feedback.

The Flux CLI is now included in Wolfi OS, the Linux (Un)distro designed for securing the software supply chain. The Chainguard team and Wolfi maintainers are shipping updates for the Flux package on a regular basis.

Features and improvements

  • Recreate immutable resources (e.g. Kubernetes Jobs) by annotating or labeling them with kustomize.toolkit.fluxcd.io/force: enabled.
  • Support for HTTPS bearer token authentication for Git repositories.
  • Improve memory usage by disabling the caching of Secret and ConfigMap resources in all controllers.
  • Better observability with progressive status updates for Sources (Git, OCI, Helm, S3 Buckets).
  • Allow extracting the OCI artifact SHA256 digest for Cosign with flux push artifact -o json.
  • Track CRDs managed by Flux, flux trace and flux tree will show which HelmRelease deployed which CRDs.
  • Allow the Flux GitHub Action to use a GitHub token when checking for updates to avoid rate limiting.
