Docker compose

Docker Compose is a tool available since 2014 for defining and running multi-container Docker applications.

Rules are defined in docker-compose.yml and executed by running docker-compose up.

docker-compose allows to define start order dependencies between containers.

For reference of valid options for docker compose check: https://docs.docker.com/compose/compose-file/

Installation

• brew install docker-compose

Basic commands

• docker-compose -h (for list of commands and options)
• docker-compose up
• docker-compose up -d

-d daemon

• Start your containers with a command line variable: YOUR_VARIABLE=YOUR_VALUE docker-compose up

• docker-compose -p NAME --project-name

Logs:

• docker-compose logs View output from containers
• docker-compose logs -f View output from containers
• docker-compose pull SERVICE_NAME or docker-compose pull. . See also: docker images

• docker-compose build
• docker-compose bundle
• docker-compose config
• docker-compose create
• docker-compose down

docker-compose down --remove-orphans

• docker-compose events
• docker-compose exec
• docker-compose help
• docker-compose images
• docker-compose kill
• docker-compose logs: docker-compose logs SERVICE_NAME (You will find your SERVICE_NAME looking into your docker-compose.yml file)
• docker-compose pause
• docker-compose port
• docker-compose ps
• docker-compose pull.docker-compose pull SERVICE_NAME. Just pull container images but do not start them. To update your image and start your services: docker-compose pull && docker-compose up -d
• docker-compose push
• docker-compose restart
• docker-compose rm
• docker-compose run
• docker-compose scale
• docker-compose start
• docker-compose stop
• docker-compose top
• docker-compose unpause
