Petr Kremensky created WFWIP-255:
------------------------------------
Summary: Existing PVC can slip into as the storage for operator
Key: WFWIP-255
URL: https://issues.jboss.org/browse/WFWIP-255
Project: WildFly WIP
Issue Type: Bug
Components: OpenShift
Reporter: Petr Kremensky
Assignee: Jeff Mesnil
PVC created manually (any accessModes) by user can be slip into the Operator.
*Things to notice here:*
* WFWIP-186 StorageSpec is intended to be mounted in ReadWriteOnce mode
* {{foo: bar}} should never pass the validation as it is not a valid storage
configuration
*reproduce*
* create PVC, use the ${APP_NAME}-volume-quickstart-0 name - the PVC would be in normal
circumstances created by the operator
