Flux technology things to know

Three more Flux release candidates! Many improvements - Please test

On our path to GA, we released v2.0.0-rc5, the fifth release candidate for the 2.0.0 release. It includes many fixes, so you are very much encouraged to upgrade to this latest version - even though it carries “RC” in its version number, it is the most stable Flux release to date. Users are advised to upgrade from v0.41 and older versions to v2.0.0-rc.5 as soon as possible.

Fixes and improvements

  • Starting with this version, source-controller, kustomize-controller and helm-controller pods are marked as system-cluster-critical.
  • The Alert v1beta2 API has two new optional fields. .spec.inclusionList for fine-grained control over events filtering (notification-controller) and .spec.metadata that allows users to enrich the alerts with information about the cluster name, region, environment, etc.
  • New command flux reconcile source chart for pulling Helm OCI charts on-demand from container registries (CLI).
  • Support annotated Git tags with .spec.ref.name in GitRepository (source-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).
  • 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).
  • Improve the detection of values changes for HelmReleases by stable sorting them by key (helm-controller)
  • Update cosign to v2 (source-controller)
  • Support for Helm 3.12.0 and Kustomize v5.0.3.

To upgrade from v0.x to v2.0.0-rc.5, 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. The upgrade to Kustomize v5 also contains breaking changes, please consult their CHANGELOG for more details.

Big thanks to all the Flux contributors that helped us with this release!

Security news

All components have been updated to patch vulnerabilities in Docker (CVE-2023-28840, CVE-2023-28841, CVE-2023-28842) and Sigstore (CVE-2023-30551, CVE-2023-33199).

Flagger 1.31.0

This release adds support for Linkerd 2.13. Furthermore, a bug which led the confirm-rollout webhook to be executed at every step of the Canary instead of only being executed before the canary deployment is scaled up, has been fixed.

Flux Fun Fact!

Did you know … 🔩 Flux works with your existing tools: Flux works with your Git providers (GitHub, GitLab, Bitbucket, can even use s3-compatible buckets as a source), all major container registries, and all CI workflow providers. GitLab also announced that Flux is their GitOps tool of choice, so you’ll see even more synergy this year!
