Highlights

This is the first General Availability (GA) release of Flux v2.

Flux v2.0.0 comes with the promotion of the GitOps related APIs to v1 and adds horizontal scaling & sharding capabilities to Flux controllers. The Git bootstrap capabilities provided by the Flux CLI and by Flux Terraform Provider are now considered stable and production ready.

Starting with this version, the build, release and provenance portions of the Flux project supply chain provisionally meet SLSA Build Level 3.

Flux GA is fully integrated with Kubernetes Workload Identity for AWS, Azure and Google Cloud to facilitate passwordless authentication to OCI sources (container images, OCI artifacts, Helm charts).

The Flux alerting capabilities have been extended with PagerDuty and Google Pub/Sub support. The improved Alert v1beta2 API provides better control over events filtering and allows users to enrich the alerts with custom metadata.

Supported versions

Starting with this version, the Flux CLI and the GA components (source-controller, kustomize-controller and notification-controller) follow the release cadence and support pledge documented in the Flux release specification.

Kubernetes compatibility

This release is compatible with the following Kubernetes versions:

Kubernetes version Minimum required
v1.24 >= 1.24.0
v1.25 >= 1.25.0
v1.26 >= 1.26.0
v1.27 >= 1.27.1

Note that Flux may work on older versions of Kubernetes e.g. 1.19, but we don't recommend running end-of-life versions in production nor do we offer support for these versions.

Flux ecosystem support

The following (open-source) extensions & integrations are compatible with this Flux release, starting from the specified minimum version or higher.

Type Project Version
Flux Web UI weave-gitops 0.26.0
Terraform integration tf-controller 0.15.0

  • 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 (replaced by .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)

Upgrade procedure

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

To upgrade the APIs from v1beta2, make sure the new CRDs and controllers are deployed, and then 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 definitions.
  4. Set apiVersion: kustomize.toolkit.fluxcd.io/v1 in the YAML files that contain Flux Kustomization definitions.
  5. Set apiVersion: notification.toolkit.fluxcd.io/v1 in the YAML files that contain Receiver definitions.
  6. Update the API version of GitRepository and Kustomization objects present in the .spec.resources list of Receiver definitions.
  7. 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.
