Steps to reproduce

I saw there is a list of pre-provisioned PVs:

NAME                      CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                                                 STORAGECLASS   REASON   AGE
persistentvolume/pv0001   100Gi      RWO,ROX,RWX    Recycle          Bound       openshift-image-registry/crc-image-registry-storage                           15d
persistentvolume/pv0002   100Gi      RWO,ROX,RWX    Recycle          Available                                                                                 15d
...
persistentvolume/pv0030   100Gi      RWO,ROX,RWX    Recycle          Available                                                                                 15d

But no storageclass is available now.

Expected

There should be at least one StorageClass embedded to make a lot of things easier.
May refer to Kind's hostpath to bundle one?
kubernetes-sigs/kind#118

Actual

No dynamic storage available

@brightzheng100 can you try https://github.com/code-ready/crc/wiki/Dynamic-volume-provisioning one as let us know if that manual steps working for you and able to use for you workloads.

[brightzheng100]

Yup, for now I'm using rancher/local-path-provisioner:

$ oc apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/master/deploy/local-path-storage.yaml
$ oc annotate storageclass/local-path storageclass.kubernetes.io/is-default-class=true
$ oc get sc
NAME                   PROVISIONER             AGE
local-path (default)   rancher.io/local-path   8m28s

Maybe it's just one of the FAQ items so the user can know what potential solutions can be used, or simply make one of the solutions embedded, as selectable add-ons, think of minikube?

[praveenkumar]

@brightzheng100 yes, we are going to embed the kubevirt hostpath provisioner by default so user can use it for stroage classes. I am going to keep this issue open till we figure out where it would be.

@praveenkumar did this ever happen? In crc 1.28.0+ I don't see it at least, so it's not clear to me what provisioner to use for a StorageClass.
