FluxCD v2 - v0.38.0

Highlights

Flux v0.38.0 comes with new features and improvements. Users are encouraged to upgrade for the best experience.

Notification API v1beta2

This release graduates the Notification APIs to v1beta2. After upgrading the controllers on your clusters, you need to update the notification Custom Resources in Git by replacing notification.toolkit.fluxcd.io/v1beta1 with notification.toolkit.fluxcd.io/v1beta2 in all YAML manifests.

Breaking changes

• The Alert.spec.summary has a max length of 255 characters.
• The Provider.spec.address and Provider.spec.proxy have a max length of 2048 characters.
• The Receiver.status.url was deprecated in favour of Receiver.status.webhookPath.

For more details about v1beta2 please see the notification-controller chagelog and the API spec documentation.

Features and improvements

• Support for defining Kustomize components with Kustomization.spec.components.
• Support for piping multi-doc YAMLs when publishing OCI artifacts with kustomize build . | flux push artifact --path=-.
• Support for Gitea commit status updates with Provider.spec.type set to gitea.
• Improve the memory usage of helm-controller by disabling the caching of Secret and ConfigMap resources.
• Update the Helm SDK to v3.10.3 (fix for Helm CVEs).
• All code references to libgit2 were removed, and the GitRepository.spec.gitImplementation field is no longer being honored.

Documentation improvements

The official example repository was refactored. The new version comes with the following improvements:

• Make the example compatible with ARM64 Kubernetes clusters.
• Add Weave GitOps Helm release to showcase the Flux UI.
• Replace the ingress-nginx Bitnami chart with the official one that contains multi-arch container images.
• Add cert-manager Helm release to showcase how to install CRDs and custom resources using dependsOn.
• Add Let's Encrypt ClusterIssuer to showcase how to patch resources in production with Flux Kustomization.
• Add the flux-system overlay to showcase how to configure Flux at bootstrap time.
