Now that we have the administration repository as well as the SSH host keys, we
can finally run HGKeeper.
The following example command makes the same assumptions as the
`setup`container did above. However, it's going to expose the container on the host's
network interface. We also run it in the background and give it a name of
`HGKeeper`. If you're just doing testing, you will probably want to remove the
`--detach`,
`--name hgkeeper`, and
`--restart=unless-stopped` options.
--restart=unless-stopped \ --volume $(pwd)/host-keys:/host-keys:ro \ --volume $(pwd)/repos:/repos \ --env HGK_SSH_HOST_KEYS=/host-keys \ --env HGK_REPOS_PATH=/repos \ docker.io/rwgrim/hgkeeper:latest \
