Command "fogger:init" is not defined

when I run docker-compose run --rm fogger fogger:init I get the error Command "fogger:init" is not defined.

Following the example from the readme, but I'm not sure what I missed.

Thanks!

@tsurowiec please let me know if this is an obvious error, I'm running my target and source db from docker.
