**NOTE**: the host mode gives the container access to changing the host's hostname and is therefore considered insecure.
**--mount**=*type=TYPE,TYPE-SPECIFIC-OPTION[,...]*
Attach a filesystem mount to the container
Current supported mount TYPES are bind, and tmpfs.
e.g.
type=bind,source=/path/on/host,destination=/path/in/container
type=tmpfs,tmpfs-size=512M,destination=/path/in/container
Common Options:
· src, source: mount source spec for bind and volume. Mandatory for bind.
· dst, destination, target: mount destination spec.
· ro, read-only: true or false (default).
Options specific to bind:
· bind-propagation: Z, z, shared, slave, private, rshared, rslave, or rprivate(default). See also mount(2).
Options specific to tmpfs:
· tmpfs-size: Size of the tmpfs mount in bytes. Unlimited by default in Linux.
· tmpfs-mode: File mode of the tmpfs in octal. (e.g. 700 or 0700.) Defaults to 1777 in Linux.

When using SELinux, be aware that the host has no knowledge of container SELinux
policy. Therefore, in the above example, if SELinux policy is enforced, the
