First we will create the HGKeeper administration repository. We will use the

normal HGKeeper container with an overridden command to run the setup. An extra

step with this method is that you will need to volume mount a file containing

the public key of the initial administrator into this invocation. In the

following example we assume that the key is in `~/.ssh/id_ed25519.pub`.

Be sure to replace the value of `my_username` with the username that would like

to use.

Also, since this container is just used for initialization of the

administration repository, we will pass the `--rm` flag to make sure it will be

deleted when done.

Once this step has completed, you should now have a `repos` directory in your

current working directory and it should have a brand new `hgkeeper`

administration repository in it. These repositories are HGKeeper's copies of

them, you should not modify them directly and should be using the SSH

capabilities of HGKeeper to push/pull to/from them.
