For when you really want to blat everything.
docker rm (docker ps -a -q) && docker rmi -f (docker image ls -q)
I'm using fish so the command substitution is a little
different to the usual bash syntax. If you're running a more standard shell, you'll probably need some
$s in there:
docker rm $(docker ps -a -q) && docker rmi -f $(docker image ls -q)
docker rm removes containers by container Id.
docker ps -a -q lists all containers in quiet mode - so just the container Ids.
The logic is the same for removing images - I've thrown in the force flag for good measure, and I've used
&& to concatenate two commands onto one line.
This will error out if you have no containers.
It's also very destructive. A nuclear option as it were.`
