## How to: get back to a clean slate

If you encounter an issue with your Docker setup and you've already exhausted all other ideas, here's a quick one-liner that stops and removes absolutely everything. You can then follow the govuk-docker README instructions for `make`-ing your app again.

```
docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q) && docker rmi $(docker images -q) -f && docker volume prune && docker container prune && docker image prune && docker network prune && docker system prune --all --volumes
```
