Development

Bug reports, feature requests, help, patches, support and everything else are welcome on the Open Infrastructure Software Mailing List (<https://lists.open-infrastructure.net/listinfo/software>).

Please base patches against the 'next' Git branch using common sense (<https://www.kernel.org/doc/Documentation/SubmittingPatches>).

Debian specific bugs can also be reported in the Debian Bug Tracking System (<https://bugs.debian.org>).

Known limitations

This version of compute-tools currently do not work with systemd-networkd and depend on ifupdown.

Using overlay, the upper directory can not be an NFS mount due to limitations in Linux' overlay filesystem (<https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/filesystems/overlayfs.txt>).

Usage

    Build a new container:
        sudo container build -n NAME

    Start a container:
        sudo container start -n NAME

    Stop a container:
        sudo container stop -n NAME

    Remove a container:
        sudo container remove -n NAME

    List container on the system:
        sudo container list

    Show container version:
        container version

See container(1) for a list of all container commands.
