Curl running instance

List all running containers

docker ps

Stop a container

docker stop <id>

Stop all containers

Delete all containers

docker rm $(docker ps -a -q)

Delete all images

docker rmi $(docker images -q)

Create bash shell to running instance by ID

Gotchas

• virtual box gives the instance its own network ip ( probably in 192.168.*.* range )
• knowing this ip address may be important to your application
• if you crash the docker vm and restart, you'll have to re-export ENV variables ( read output of boot2docker up )
• all configuration paths in your application should be based to __dirname ( if not already )
• don't forget to run docker-compose build before docker-compose up
