Helm Releases

The GitOps Toolkit Custom Resource Definitions documentation.

The HelmRelease API defines a resource for automated controller driven Helm releases.

Specification

A HelmRelease object defines a resource for controller driven reconciliation of Helm releases via Helm actions such as install, upgrade, test, uninstall, and rollback. This includes release placement (namespace/name), release content (chart/values overrides), action trigger configuration, individual action configuration, and statusing.

// HelmReleaseSpec defines the desired state of a Helm Release.
type HelmReleaseSpec struct {
	// Chart defines the template of the v1beta1.HelmChart that should be created
	// for this HelmRelease.

Helm release placement

The namespace/name in which to deploy and store the Helm release defaults to the namespace/name of the HelmRelease. These can be overridden respectively via spec.targetNamespace, spec.storageNamespace and spec.releaseName. If spec.targetNamespace is set, spec.releaseName defaults to <spec.targetNamespace>-<metadata.name>.

Note: that configuring the spec.targetNamespace only defines the namespace the release is made in, the metadata for the release (also known as the “Helm storage”) will be stored in the metadata.namespace or spec.storageNamespace of the HelmRelease.

Helm chart template

The spec.chart values are used by the helm-controller as a template to create a new HelmChart resource with the given spec.

The spec.chart.spec.sourceRef is a reference to an object managed by source-controller. When the source revision changes, it generates a Kubernetes event that triggers a new release.

Supported source types:

The HelmChart is created in the same namespace as the sourceRef, with a name matching the HelmRelease <metadata.namespace>-<metadata.name>.

Note that on multi-tenant clusters, platform admins can disable cross-namespace references with the --no-cross-namespace-refs=true flag. When this flag is set, the HelmRelease can only refer to sources in the same namespace as the HelmRelease object.

The chart.spec.chart can either contain:

  • The name of the chart as made available by the HelmRepository (without any aliases), for example: podinfo
  • The relative path the chart can be found at in the GitRepository, for example: ./charts/podinfo

The chart.spec.version can be a fixed semver, or any semver range (i.e. >=4.0.0 <5.0.0). It is ignored for HelmRelease resources that reference a GitRepository or Bucket source.

Annotations and labels can be added by configuring the respective .spec.chart.metadata fields.

Values overrides

The simplest way to define values overrides is inline via spec.values. It is also possible to define a list of ConfigMap and Secret resources from which to take values via spec.valuesFrom. The values are merged in the order given, with the later values overwriting earlier, and then spec.values overwriting those:

spec:
  values:
    replicaCount: 2
  valuesFrom:
    - kind: ConfigMap
      name: prod-env-values
      valuesKey: values-prod.yaml
    - kind: Secret
      name: prod-tls-values
      valuesKey: crt
      targetPath: tls.crt
      optional: true

The definition of the listed keys for items in spec.valuesFrom is as follows:

  • kind: Kind of the values referent (ConfigMap or Secret).
  • name: Name of the values referent, in the same namespace as the HelmRelease.
  • valuesKey (Optional): The data key where the values.yaml or a specific value can be found. Defaults to values.yaml when omitted.
  • targetPath (Optional): The YAML dot notation path at which the value should be merged. When set, the valuesKey is expected to be a single flat value. Defaults to None when omitted, which results in the values getting merged at the root.
  • optional (Optional): Whether this values reference is optional. When true, a not found error for the values reference is ignored, but any valuesKey, targetPath or transient error will still result in a reconciliation failure. Defaults to false when omitted.

Note: that the targetPath supports the same formatting as you would supply as an argument to the helm binary using --set [path]=[value]. In addition to this, the referred value can contain the same value formats (e.g. {a,b,c} for a list). You can read more about the available formats and limitations in the Helm documentation.

Reconciliation

If no Helm release with the matching namespace/name is found it will be installed. It will be upgraded any time the desired state is updated, which consists of:

  • spec (and thus metadata.generation)
  • Latest HelmChart revision available
  • ConfigMap and Secret values overrides. Changes to these do not trigger an immediate reconciliation, but will be handled upon the next reconciliation. This is to avoid a large number of upgrades occurring when multiple resources are updated.

If the latest Helm release revision was not made by the helm-controller, it may not match the desired state, so an upgrade is made in this case as well.

The spec.interval tells the reconciler at which interval to reconcile the release. The interval time units are s, m and h e.g. interval: 5m, the minimum value should be 60 seconds.

The reconciler can be told to reconcile the HelmRelease outside of the specified interval by annotating the object with a reconcile.fluxcd.io/requestedAt annotation. For example:

kubectl annotate --overwrite helmrelease/podinfo reconcile.fluxcd.io/requestedAt="$(date +%s)"

Reconciliation can be suspended by setting spec.suspend to true.

The timeout for any individual Kubernetes operation (like Jobs for hooks) during the performance of Helm actions can be configured via spec.timeout and can be overridden per action via spec.<action>.timeout.

List all Kubernetes objects reconciled from a HelmRelease:

kubectl get all --all-namespaces \
-l=helm.toolkit.fluxcd.io/name="<HelmRelease name>" \
-l=helm.toolkit.fluxcd.io/namespace="<HelmRelease namespace>"

Disabling resource waiting

For install, upgrade, rollback, and uninstall actions resource waiting is enabled by default, but can be disabled by setting spec.<action>.disableWait.

Waiting for jobs to complete is enabled by default, but can be disabled by setting spec.<action>.disableWaitForJobs.

HelmRelease dependencies

When applying a HelmRelease, you may need to make sure other releases are Ready before the release is reconciled. For example, because your chart relies on the presence of a Custom Resource Definition installed by another HelmRelease. The spec.dependsOn field allows you to specify each of these dependencies.

Assuming two HelmRelease resources:

  • backend - contains the backend of the application
  • frontend - contains the frontend of the application and relies on the backend
apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: backend
  namespace: default
spec:
  interval: 5m
  chart:
    spec:
      chart: podinfo
      version: ">=4.0.0 <5.0.0"
      sourceRef:
        kind: HelmRepository
        name: podinfo
        namespace: default
      interval: 1m
  upgrade:
    remediation:
      remediateLastFailure: true
  test:
    enable: true
  values:
    service:
      grpcService: backend
    resources:
      requests:
        cpu: 100m
        memory: 64Mi
---
apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: frontend
  namespace: default
spec:
  interval: 5m
  chart:
    spec:
      chart: podinfo
      version: ">=4.0.0 <5.0.0"
      sourceRef:
        kind: HelmRepository
        name: podinfo
        namespace: default
      interval: 1m
  dependsOn:
    - name: backend
  upgrade:
    remediation:
      remediateLastFailure: true
  test:
    enable: true
  values:
    backend: http://backend-podinfo:9898/echo
    resources:
      requests:
        cpu: 100m
        memory: 64Mi

Note that this does not account for upgrade ordering. Kubernetes only allows applying one resource (HelmRelease in this case) at a time, so there is no way for the controller to know when a dependency HelmRelease may be updated. Also, circular dependencies between HelmRelease resources must be avoided, otherwise the interdependent HelmRelease resources will never be reconciled.

Configuring Helm test actions

To make the controller run the Helm tests available for your chart after a successful Helm install or upgrade, spec.test.enable should be set to true.

By default, when tests are enabled, failures in tests are considered release failures, and thus are subject to the triggering Helm action’s remediation configuration. However, test failures can be ignored by setting spec.test.ignoreFailures to true. In this case, no remediation will be taken, and the test failure will not affect the Released and Ready status conditions. This can be overridden per Helm action by setting spec.install.remediation.ignoreTestFailures or spec.upgrade.remediation.ignoreTestFailures.

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: podinfo
  namespace: default
spec:
  interval: 5m
  chart:
    spec:
      chart: podinfo
      version: ">=4.0.0 <5.0.0"
      sourceRef:
        kind: HelmRepository
        name: podinfo
        namespace: default
      interval: 1m
  test:
    enable: true
    ignoreFailures: true
  values:
    resources:
      requests:
        cpu: 100m
        memory: 64Mi

Configuring failure remediation

From time to time a Helm install/upgrade and accompanying Helm test may fail. When this occurs, by default no action is taken, and the release is left in a failed state. However, several automatic failure remediation options can be set via spec.install.remediation and spec.upgrade.remediation.

The retries can be set to configure the number of retries after an initial failure. A negative integer results in infinite retries. This implicitly opts-in to a remediation action between each attempt. The remediation action for install failures is an uninstall. The remediation action for upgrade failures is by default a rollback, however spec.upgrade.remediation.strategy can be set to uninstall, in which case after the uninstall, the spec.install configuration takes over.

One can also opt-in to remediation of the last failure (when no retries remain) by setting spec.<action>.remediation.remediateLastFailure to true. For upgrades, this defaults to true if at least one retry is configured.

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: podinfo
  namespace: default
spec:
  interval: 5m
  chart:
    spec:
      chart: podinfo
      version: ">=4.0.0 <5.0.0"
      sourceRef:
        kind: HelmRepository
        name: podinfo
        namespace: default
      interval: 1m
  install:
    remediation:
      retries: 3
  upgrade:
    remediation:
      remediateLastFailure: false
  values:
    resources:
      requests:
        cpu: 100m
        memory: 64Mi

Role-based access control

By default, a HelmRelease runs under the cluster admin account and can create, modify, delete cluster level objects (cluster roles, cluster role binding, CRDs, etc) and namespeced objects (deployments, ingresses, etc). For certain HelmReleases a cluster admin may wish to control what types of Kubernetes objects can be reconciled and under which namespace. To restrict a HelmRelease, one can assign a service account under which the reconciliation is performed.

Assuming you want to restrict a group of HelmReleases to a single namespace, you can create an account with a role binding that grants access only to that namespace:

apiVersion: v1
kind: Namespace
metadata:
  name: webapp
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: webapp-reconciler
  namespace: webapp
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: webapp-reconciler
  namespace: webapp
rules:
  - apiGroups: ["*"]
    resources: ["*"]
    verbs: ["*"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: webapp-reconciler
  namespace: webapp
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: webapp-reconciler
subjects:
  - kind: ServiceAccount
    name: webapp-reconciler
    namespace: webapp

Note that the namespace, RBAC and service account manifests should be placed in a Git source and applied with a Kustomization.

Create a HelmRelease that prevents altering the cluster state outside of the webapp namespace:

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: podinfo
  namespace: webapp
spec:
  serviceAccountName: webapp-reconciler
  interval: 5m
  chart:
    spec:
      chart: podinfo
      sourceRef:
        kind: HelmRepository
        name: podinfo

When the controller reconciles the podinfo release, it will impersonate the webapp-reconciler account. If the chart contains cluster level objects like CRDs, the reconciliation will fail since the account it runs under has no permissions to alter objects outside of the webapp namespace.

Enforce impersonation

On multi-tenant clusters, platform admins can enforce impersonation with the --default-service-account flag.

When the flag is set, all HelmReleases which don’t have spec.serviceAccountName specified will use the service account name provided by --default-service-account=<SA Name> in the namespace of the object.

Remote Clusters / Cluster-API

If the spec.kubeConfig field is set, Helm actions will run against the default cluster specified in that KubeConfig instead of the local cluster that is responsible for the reconciliation of the HelmRelease.

The secret defined in the spec.kubeConfig.secretRef must exist in the same namespace as the HelmRelease. On every reconciliation, the KubeConfig bytes will be loaded from the .secretRef.key key (default: value or value.yaml) of the Secret’s data , and the Secret can thus be regularly updated if cluster-access-tokens have to rotate due to expiration.

The Helm storage is stored on the remote cluster in a namespace that equals to the namespace of the HelmRelease, or the configured spec.storageNamespace. The release itself is made in a namespace that equals to the namespace of the HelmRelease, or the configured spec.targetNamespace. The namespaces are expected to exist, with the exception that spec.targetNamespace can be created on demand by Helm when spec.install.createNamespace is set to true.

Other references to Kubernetes resources in the HelmRelease, like ValuesReference resources, are expected to exist on the reconciling cluster.

This composes well with Cluster API bootstrap providers such as CAPBK (kubeadm), as well as the CAPA (AWS) EKS integration.

To reconcile a HelmRelease to a CAPI controlled cluster, put the HelmRelease in the same namespace as your Cluster object, and set the spec.kubeConfig.secretRef.name to <cluster-name>-kubeconfig:

apiVersion: cluster.x-k8s.io/v1alpha3
kind: Cluster
metadata:
  name: stage # the kubeconfig Secret will contain the Cluster name
  namespace: capi-stage
spec:
  clusterNetwork:
    pods:
      cidrBlocks:
        - 10.100.0.0/16
    serviceDomain: stage-cluster.local
    services:
      cidrBlocks:
        - 10.200.0.0/12
  controlPlaneRef:
    apiVersion: controlplane.cluster.x-k8s.io/v1alpha3
    kind: KubeadmControlPlane
    name: stage-control-plane
    namespace: capi-stage
  infrastructureRef:
    apiVersion: infrastructure.cluster.x-k8s.io/v1alpha3
    kind: DockerCluster
    name: stage
    namespace: capi-stage
---
# ... unrelated Cluster API objects omitted for brevity ...
---
apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: kube-prometheus-stack
  namespace: capi-stage
spec:
  kubeConfig:
    secretRef:
      name: stage-kubeconfig # Cluster API creates this for the matching Cluster
  chart:
    spec:
      chart: prometheus
      version: ">=4.0.0 <5.0.0"
      sourceRef:
        kind: HelmRepository
        name: prometheus-community
  install:
    remediation:
      retries: -1

The Cluster and HelmRelease can be created at the same time if the install remediation configuration is set to a forgiving amount of retries. The HelmRelease will then eventually reconcile once the cluster is available.

If you wish to target clusters created by other means than CAPI, you can create a ServiceAccount on the remote cluster, generate a KubeConfig for that account, and then create a secret on the cluster where helm-controller is running e.g.:

kubectl -n default create secret generic prod-kubeconfig \
    --from-file=value.yaml=./kubeconfig

Note that the KubeConfig should be self-contained and not rely on binaries, environment, or credential files from the helm-controller Pod. This matches the constraints of KubeConfigs from current Cluster API providers. KubeConfigs with cmd-path in them likely won’t work without a custom, per-provider installation of helm-controller.

When both spec.kubeConfig and spec.ServiceAccountName are specified, the controller will impersonate the service account on the target cluster.

Post Renderers

HelmRelease resources has a built-in Kustomize compatible Post Renderer, which provides the following Kustomize directives:

The following example uses the built-in kustomize Post Renderer to apply a strategic merge patch, which adds a toleration to the Helm rendered output:

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: metrics-server
  namespace: kube-system
spec:
  interval: 1m
  chart:
    spec:
      chart: metrics-server
      version: "5.3.4"
      sourceRef:
        kind: HelmRepository
        name: bitnami
        namespace: kube-system
      interval: 1m
  postRenderers:
    # Instruct helm-controller to use built-in "kustomize" post renderer.
    - kustomize:
        # Array of inline strategic merge patch definitions as YAML object.
        # Note, this is a YAML object and not a string, to avoid syntax
        # indention errors.
        patchesStrategicMerge:
          - kind: Deployment
            apiVersion: apps/v1
            metadata:
              name: metrics-server
            spec:
              template:
                spec:
                  tolerations:
                    - key: "workload-type"
                      operator: "Equal"
                      value: "cluster-services"
                      effect: "NoSchedule"
        # Array of inline JSON6902 patch definitions as YAML object.
        # Note, this is a YAML object and not a string, to avoid syntax
        # indention errors.
        patchesJson6902:
          - target:
              version: v1
              kind: Deployment
              name: metrics-server
            patch:
              - op: add
                path: /spec/template/priorityClassName
                value: system-cluster-critical
        images:
          - name: docker.io/bitnami/metrics-server
            newName: docker.io/bitnami/metrics-server
            newTag: 0.4.1-debian-10-r54

CRDs

Helm does support installing CRDs, but it has no native support for upgrading CRDs:

There is no support at this time for upgrading or deleting CRDs using Helm. This was an explicit decision after much community discussion due to the danger for unintentional data loss. Furthermore, there is currently no community consensus around how to handle CRDs and their lifecycle. As this evolves, Helm will add support for those use cases.

If your write your own Helm Charts you can work-around this limitation by putting your CRDs into the templates instead of the crds directory or by out-factoring them into a separate Helm Chart as suggested by the offical Helm documentation.

However, if you have to integrate and use many existing (upstream) Helm Charts, not being able to upgrade the CRDs via Flux’s HelmRelease objects might become a cumbersome limitation within your GitOps workflow. Therefore, Flux allows you to opt-in to upgrading CRDs by setting the crds policy on the HelmRelease.spec.install and HelmRelease.spec.upgrade objects.

The following CRD upgrade policies are supported:

  • Skip Skip CRDs do neither install nor replace (update) any CRDs.
  • Create Only create new CRDs which do not yet exist, neither update nor delete any existing CRDs.
  • CreateReplace Create new CRDs, update (replace) existing ones, but do not delete CRDs which no longer exist in the current helm release.

Example:

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: my-operator
  namespace: default
spec:
  interval: 1m
  chart:
    spec:
      chart: my-operator
      version: "1.0.1"
      sourceRef:
        kind: HelmRepository
        name: my-operator-repo
        namespace: default
      interval: 1m
  install:
    crds: CreateReplace
  upgrade:
    crds: CreateReplace

Drift detection

Note: This feature is experimental and can be enabled by setting --feature-gates=DetectDrift=true.

When a HelmRelease is in-sync with the Helm release object in the storage, the controller will compare the manifests from the Helm storage with the current state of the cluster using a server-side dry-run apply. If this comparison detects a drift (either due resource being created or modified during the dry-run), the controller will perform an upgrade for the release, restoring the desired state.

To help aid transition to this new feature, it is possible to enable drift detection without it correcting drift. This can be done by adding CorrectDrift=false to the --feature-gates flag, i.e. --feature-gates=DetectDrift=true,CorrectDrift=false. This will allow you to see what drift is detected in the controller logs (with --log-level=debug), to potentially add the appropriate exclusions annotations or labels, before enabling the feature full.

Excluding resources from drift detection

The drift detection feature can be configured to exclude certain resources from the comparison by labeling or annotating them with helm.toolkit.fluxcd.io/driftDetection: disabled. Using post-renderers, this can be applied to any resource rendered by Helm.

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: app
  namespace: webapp
spec:
  postRenderers:
    - kustomize:
        patches:
          - target:
              version: v1
              kind: Deployment
              name: my-app
            patch: |
              - op: add
                path: /metadata/annotations/helm.toolkit.fluxcd.io~1driftDetection
                value: disabled              

Note: For some charts, we have observed the drift detection feature can detect spurious changes due to Helm not properly patching an object, which seems to be related to Helm#5915 and issues alike. In this case (and when possible for your workload), configuring .spec.upgrade.force to true might be a more fitting solution than ignoring the object in full.

Status

When the controller completes a reconciliation, it reports the result in the status sub-resource.

The following status.conditions types are advertised. Here, “desired state” is as detailed in reconciliation:

  • Ready - status of the last reconciliation attempt
  • Released - status of the last release attempt (install/upgrade/test) against the latest desired state
  • TestSuccess - status of the last test attempt against the latest desired state
  • Remediated - status of the last remediation attempt (uninstall/rollback) due to a failure of the last release attempt against the latest desired state

For example, you can wait for a successful helm-controller reconciliation with:

kubectl wait helmrelease/podinfo --for=condition=ready

Each of these conditions also include descriptive reason / message fields as to why the status is as such.
