Mapping a single KubeVirt CSI volume snapshot class

You can expose your infrastructure volume snapshot class to the hosted cluster by using KubeVirt CSI.

Procedure

To map your volume snapshot class to the hosted cluster, use the --infra-volumesnapshot-class-mapping argument when creating a hosted cluster as shown in the following example:

$ hcp create cluster kubevirt \
  --name my-hosted-cluster \
  --node-pool-replicas 2 \
  --pull-secret /user/name/pullsecret \
  --memory 8Gi \
  --cores 2 \
  --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class> \
  --infra-volumesnapshot-class-mapping=<infrastructure_volume_snapshot_class>/<hosted_volume_snapshot_class>

--name specifies the name of your hosted cluster.
--node-pool-replicas specifies the worker count.
--pull-secret specifies the path to your pull secret.
--memory specifies a value for memory.
--cores specifies a value for CPU.
--infra-storage-class-mapping specifies the storage classes. Replace <infrastructure_storage_class> with the storage class in the infrastructure cluster, and replace <hosted_storage_class> with the storage class in the hosted cluster.

--infra-volumesnapshot-class-mapping specifies the volume snapshot classes. Replace <infrastructure_volume_snapshot_class> with the volume snapshot class in the infrastructure cluster, and replace <hosted_volume_snapshot_class> with the volume snapshot class in the hosted cluster.

If you do not use the --infra-storage-class-mapping and --infra-volumesnapshot-class-mapping arguments, a hosted cluster is created with the default storage class and the volume snapshot class. Therefore, you must set the default storage class and the volume snapshot class in the infrastructure cluster.
