  • Each container is equipped with its own independent data volume, available at /data/ in the respective container.
  • Both containers share the contents of the data volume, have full permissions to alter its content and mutually see their respective changes.
  • The original content of the container image data is available in both containers, although changes stay local within each container.
  • The second command invocation fails with an error stating that the volume data is already associated with a running container.
