--bind=, --bind-ro=
Bind mount a file or directory from the host into the container. Takes one of: a path argument — in which case the specified path will be mounted from the host to the same path in the container, or a colon-separated pair of paths — in which case the first specified path is the source in the host, and the second path is the destination in the container, or a colon-separated triple of source path, destination path and mount options. The source path may optionally be prefixed with a "+" character. If so, the source path is taken relative to the image's root directory. This permits setting up bind mounts within the container image. The source path may be specified as empty string, in which case a temporary directory below the host's /var/tmp/ directory is used. It is automatically removed when the container is shut down. Mount options are comma-separated and currently, only rbind and norbind are allowed, controlling whether to create a recursive or a regular bind mount. Defaults to "rbind". Backslash escapes are interpreted, so "\:" may be used to embed colons in either path. This option may be specified multiple times for creating multiple independent bind mount points. The --bind-ro= option creates read-only bind mounts.
