I have setup kubernetes Cluster and mounted volume mount as gcePersistentDisk in Google Cloud, It claims and mount successfully in Pods. But i want to access this volume externally so that i can write it through git/ssh or manual. As disk is Already used and mounted i cannot access it. How to write files through externally?
gcePersistentDisk is a network-based disk, and provisioned volumes can only be used by GCE instances in the same project and zone.
The fact is that this kind of resource supports readWriteOnce and ReadOnlyMany . You can use a GCE persistent storage to share data as read-only between multiple pods in the same zone.
Back to your question: you can write on this volume only from one pod . No other pods can use it as write storage - neither external nor from the same project.
