+
+Mount volumes from the specified container(s). Used to share volumes between
+containers<<| and pods>>. The *options* is a comma-separated list with the following available elements:
+
+* **rw**|**ro**
+* **z**
+
+Mounts already mounted volumes from a source container onto another
+<<container|pod>>. _CONTAINER_ may be a name or ID.
+To share a volume, use the --volumes-from option when running
+the target container. Volumes can be shared even if the source container
+is not running.
+
+By default, Podman mounts the volumes in the same mode (read-write or
+read-only) as it is mounted in the source container.
+This can be changed by adding a `ro` or `rw` _option_.
+
+Labeling systems like SELinux require that proper labels are placed on volume
+content mounted into a <<container|pod>>. Without a label, the security system might
+prevent the processes running inside the container from using the content. By
+default, Podman does not change the labels set by the OS.
+
+To change a label in the <<container|pod>> context, add `z` to the volume mount.
+This suffix tells Podman to relabel file objects on the shared volumes. The `z`
+option tells Podman that two entities share the volume content. As a result,
+Podman labels the content with a shared content label. Shared volume labels allow
+all containers to read/write content.
+
+If the location of the volume from the source container overlaps with
+data residing on a target <<container|pod>>, then the volume hides
+that data on the target.
