2. docker run -v $PWD:/home/web -it cakephp composer create-project --prefer-dist cakephp/app testing
3. edit testing/config/app.php and change the database driver..
4. docker run -v $PWD:/home/web -p 8765:8765 -it cakephp testing/bin/cake server -H 0.0.0.0

If you want migrations (or want to install other plugins):
