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,keyFileandcertFilekeys.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-metricsCRD exporter to report metrics containing rich information about Flux reconciliation status e.g. Git revision, Helm chart version, OCI artifacts digests, etc. Thegotk_reconcile_conditionmetrics was deprecated in favor of thegotk_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.nameis an optional field used to specify the name of a Kubernetes Secret that contains the HTTP/S or SOCKS5 proxy settings..spec.verify.modenow support one of the following valuesHEAD,Tag,TagAndHEAD.Kustomization v1
The Kustomization API was extended with two apply policies
IfNotPresentandIgnore.Changing the apply behaviour for specific Kubernetes resources, can be done using the following annotations:
kustomize.toolkit.fluxcd.io/ssaOverrideOverride-
Merge-
IfNotPresent-
Ignorekustomize.toolkit.fluxcd.io/forceDisabledEnabled-
Disabledkustomize.toolkit.fluxcd.io/pruneEnabledEnabled-
DisabledThe
IfNotPresentpolicy instructs the controller to only apply the Kubernetes resources if they are not present on the cluster.This policy can be used for Kubernetes
SecretsandValidatingWebhookConfigurationsmanaged 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.refspecis an optional field used to specify a Git refspec used when pushing commits upstream..spec.git.push.optionsis 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:.spec.secretRefhas been deprecated in favor of a new field.spec.certSecretRef.caFile,keyFileandcertFilekeys in the Secret specified in.spec.certSecretRefhave been deprecated in favor ofca.crt,tls.keyandtls.crt.caFile,keyFileandcertFilekeys in the Secret specified in.spec.certSecretRefhave been deprecated in favor ofca.crt,tls.keyandtls.crt..spec.secretRefusing theca.crtkey, which takes precedence over thecaFilekey.Upgrade procedure

v2.0.xtov2.1.0either by rerunning bootstrap or by using the Flux GitHub Action.To upgrade Flux from
