roryrjb/ubuntu-systemd repository overview

The official Docker image for 18.04 doesn't include systemd, this image does, it's as simple as that.

To run this properly, you'll need to do something like this:

$ docker run \
    --tmpfs /run \
    -v /sys/fs/cgroup:/sys/fs/cgroup:ro \
    --stop-signal SIGRTMIN+3 \
    roryrjb/ubuntu-systemd:18.04
