Note
By default, the provider ignores any annotations whose key names end with kubernetes.io. This is necessary because such annotations can be mutated by server-side components and consequently cause a perpetual diff in the Terraform plan output. If you explicitly specify any such annotations in the configuration template then Terraform will consider these as normal resource attributes and manage them as expected (while still avoiding the perpetual diff problem). For more info see Kubernetes reference

These arguments are the same as the for the spec block of a Pod.
Please see the Pod resource for reference.
One or more volume_claim_template blocks can be specified.
Each takes the same attributes as a kubernetes_persistent_volume_claim resource.
Please see its documentation for reference.
