Using microk8s registry with ceph storage

[ACodingfreak]

Hi All,

Looks like on enabling microk8s registry, hostpath-storage is enabled by default. Is there a way to make registry use underlying ceph storage instead of hostpath-storage ?

$ microk8s enable registry

Infer repository core for addon hostpath-storage
Enabling default storage class.
