Webhooks

Enable Webhooks

  • Webhooks are enabled in Crossplane by default from v1.13 onwards. For previous versions of Crossplane, include the flag --set webhooks.enabled=true when installing Crossplane via Helm.

Bucket Admission Controlling Webhook

Provider Ceph provides Dynamic Admission Control for Buckets.

Bucket Validation Webhook

Validates Bucket CRs for Create and Update operations. This webhook is also configured with an objectSelector label provider-ceph.crossplane.io/validation-required: true. It is the responsibility of the user (or the external system) to ensure that incoming Bucket CRs are given this label to enable webhook validation, should validation for the CR be desired.

Create and Update operations on Buckets are blocked by the bucket admission webhook when:

  • The Bucket contains one or more providers (bucket.spec.Providers) that do not exist (i.e. a ProviderConfig of the same name does not exist in the k8s cluster).
  • Bucket Lifecycle Configurations cannot be validated against a backend.
