Regarding OpenEBS iscsi provisioner: How to use ReadOnlyMany with iscsi?
When I apply it on kubernetes pod it gives the following error:
(x12 over ) openebs.io/provisioner-iscsi openebs-provisioner-5569654c96-4rlsn 760ae66d-9ebc-11e8-97d4-823996605407 Failed to provision volume with StorageClass "openebs-standard": Invalid Access Modes: [ReadOnlyMany], Supported Access Modes: [ReadWriteOnce]
How to fix that?
Short answer no. Most volume types in Kubernetes are supported as ReadWriteOnce.
Use cases for ReadOnlyMany are limited. If you are trying to share things among pods you can take a look at ConfigMaps or Secrets
