My idea was to use a busybox container to create a mysql configuration file and save it in the persistent volume to enable logs on the MySQL container! The init container keeps restarting with the Init:RunContainerError error. After checking the container logs for errors, I get the following message - error: only one of -c or an inline [CONTAINER] arg is allowed
