v2.1.0

Compare Source

Highlights

Flux v2.1.0 is a feature release. Users are encouraged to upgrade for the best experience.

The Flux APIs were extended with new opt-in features in a backwards-compatible manner.

The Flux Git capabilities have been improved with support for Git push options, Git refspec, Gerrit, HTTP/S and SOCKS5 proxies.

The Flux alerting capabilities have been extended with Datadog support.

The Flux controllers come with performance improvements when reconciling Helm repositories with large indexes (80% memory reduction), and when reconciling Flux Kustomizations with thousands of resources (x4 faster server-side apply). The load distribution has been improved when reconciling Flux objects in parallel to reduce CPU and memory spikes.

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

Deprecations

Flux v2.1.0 comes with support for Kubernetes TLS Secrets when referring to secrets containing TLS certs, and deprecates the usage of caFile, keyFile and certFile keys.

For more details about the TLS changes please see the Kubernetes TLS Secrets section.

Flux v2.1.0 comes with major improvements to the Prometheus monitoring stack. Starting with this version, Flux is leveraging the kube-state-metrics CRD exporter to report metrics containing rich information about Flux reconciliation status e.g. Git revision, Helm chart version, OCI artifacts digests, etc. The gotk_reconcile_condition metrics was deprecated in favor of the gotk_resource_info.

For more details about the new monitoring stack please see the Flux Prometheus metrics documentation and the flux2-monitoring-example repository.

API changes
GitRepository v1

The GitRepository API was extended with the following fields:

  • .spec.proxySecretRef.name is an optional field used to specify the name of a Kubernetes Secret that contains the HTTP/S or SOCKS5 proxy settings.
  • .spec.verify.mode now support one of the following values HEAD, Tag, TagAndHEAD.
Kustomization v1

The Kustomization API was extended with two apply policies IfNotPresent and Ignore.

Changing the apply behaviour for specific Kubernetes resources, can be done using the following annotations:

Annotation Default Values Role
kustomize.toolkit.fluxcd.io/ssa Override - Override
- Merge
- IfNotPresent
- Ignore		 Apply policy
kustomize.toolkit.fluxcd.io/force Disabled - Enabled
- Disabled		 Recreate policy
kustomize.toolkit.fluxcd.io/prune Enabled - Enabled
- Disabled		 Delete policy

The IfNotPresent policy instructs the controller to only apply the Kubernetes resources if they are not present on the cluster.
This policy can be used for Kubernetes Secrets and ValidatingWebhookConfigurations managed by cert-manager,
where Flux creates the resources with fields that are later on mutated by other controllers.

ImageUpdateAutomation v1beta1

The ImageUpdateAutomation was extended with the following fields:

  • .spec.git.push.refspec is an optional field used to specify a Git refspec used when pushing commits upstream.
  • .spec.git.push.options is an optional field used to specify the Git push options to be sent to the Git server when pushing commits upstream.
Kubernetes TLS Secrets

All the Flux APIs that accept TLS data have been modified to adopt Secrets of type
kubernetes.io/tls. This includes:

  • HelmRepository: The field .spec.secretRef has been deprecated in favor of a new field .spec.certSecretRef.
  • OCIRepository: Support for the caFile, keyFile and certFile keys in the Secret specified in .spec.certSecretRef have been deprecated in favor of ca.crt, tls.key and tls.crt.
  • ImageRepository: Support for thecaFile, keyFile and certFile keys in the Secret specified in .spec.certSecretRef have been deprecated in favor of ca.crt, tls.key and tls.crt.
  • GitRepository: CA certificate can now be provided in the Secret specified in .spec.secretRef using the ca.crt key, which takes precedence over the caFile key.

v2.0.0

Compare Source

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
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 (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)

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

  • the deprecated field .status.url was removed (replaced by .status.webhookPath)
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.
