Overview
Container-Generated Data Storage Operations
If the container has volume mount points specified with VOLUME in its original Dockerfile, those mount points must be bound to paths on the native host when the container is created. This is done with --v|--volume or --mount (recommended) command line options, as follows:
docker run ... --mount type=bind,src=<native-host-path>,dst=<container-mount-point> ...
docker run ... --mount type=bind,src=/data-volumes/postgresql,dst=/var/lib/pgsql/data ...
docker run ... -v <native-host-path>:<container-mount-point> ...
When --mount with type=bind is used, the native-host-path must refer to an existing path on the host. The path will not be created if it does not exist, and the command will fail. Also, the mount point must have sufficient permissions. For more details on native host path permissions, see Native Host Path Permissions.
