Bash Completion

version="$(docker-compose version --short)"

curl -L "https://raw.githubusercontent.com/docker/compose/$version/contrib/completion/bash/docker-compose" \
     -o /etc/bash_completion.d/docker-compose

Docker Compose File Override

Start / restart containers from docker-compose.yml and docker-compose.override.yml

export COMPOSE_FILE=jenkins-docker-compose.yml

docker-compose up

Notable Switches:

Switch	Description
-d	detached
-p	<project_name>
-f	alternative-docker-compose.yml

docker-compose -d -f docker-compose.yml -f docker-compose.prod.yml up

Only starts previously created containers

docker-compose start

Equivalent of docker run -ti:

docker-compose run -e DEBUG=1 $service $command

If DEBUG doesn't have a value argument it'll take DEBUG from the environment variable DEBUG

docker-compose exec $service $command

docker-compose down
