Version Information Enterprise

There are now multiple published versions of the template CRD.

Migration notes​

v1alpha1 to v1alpha2​

When manually migrating a template from v1alpha1 to v1alpha2 (for example in git) you will need to:

  1. Update the apiVersion to templates.weave.works/v1alpha2
  2. Move the spec.resourcetemplates field to spec.resourcetemplates[0].contents
  3. Either leave the spec.resourcetemplates[0].path field empty or give it a sensible value.

If you experience issues with the path not being recognised when Flux reconciles the new template versions, try manually applying the new template to the cluster directly with:

  1. Run kubectl apply -f capi-template.yaml
  2. Run flux reconcile kustomization --with-source flux-system twice.

Conversion Webhook​

A conversion webhook is hosted by the flux-system/templates-controller-webhook-service service. v1alpha1 templates are automatically converted to v1alpha2 when they are loaded into the cluster.

v1alpha1 to v1alpha2 conversion​

The spec.resourcetemplates field is moved to spec.resourcetemplates[0].contents and the spec.resourcetemplates[0].path is left empty. When the tempalte is rendered the spec.resourcetemplates[0].path field has a default value calculated.

v1alpha2 (default) notes​

This version changes the type of spec.resourcetemplates from a list of objects to a list of files with a path and contents:

Example:

spec:
  resourcetemplates:
    - path: "clusters/{{ .params.CLUSTER_NAME }}.yaml"
      contents:
        - apiVersion: cluster.x-k8s.io/v1alpha3
          kind: Cluster
          metadata:
            name: "{{ .params.CLUSTER_NAME }}"
          path: "clusters/{{ .params.CLUSTER_NAME }}.yaml"

v1alpha1 notes​

The original version of the template. This version is deprecated and will be removed in a future release.

It uses spec.resourcetemplates as a list of resources to render.

Example:

spec:
  resourcetemplates:
    - apiVersion: cluster.x-k8s.io/v1alpha3
      kind: Cluster
      metadata:
        name: "{{ .params.CLUSTER_NAME }}"
