Then please update your installed docker version

How can I start a fresh docker environment?

To completely start fresh and change the directory that mwcli expects your mediawiki checkout to be in you need to clear the environment. Run:

$ mw docker env clear

Until you do this, other commands that would normally prompt you to choose where to check out mediawiki will assume you're already part-way into the setup process and just direct you to get-code.

You can be more precise and just delete the MEDIAWIKI_VOLUMES_CODE var if you prefer.
