Совсем недавно, после выхода Compose 1.6.0+ и Docker 1.10.0+, стала доступна 2 версия.
Добавлены ключи: services, volumes, networks. Будут удалены ключи: links.
Version 1
# docker-compose.yml app: build: . ports: - '3000:3000' volumes: - .:/home/web links: - db db: image: sameersbn/postgresql ports: - '5432' volumes_from: - db_data env_file: - $HOME/.docker/$APP/db.env db_data: image: tianon/true volumes: - /var/lib/postgresql
# config/database.yml development: adapter: postgresql encoding: unicode database: <%= ENV['DB_ENV_DB_NAME'] %> pool: 5 username: <%= ENV['DB_ENV_DB_USER'] %> password: <%= ENV['DB_ENV_DB_PASS'] %> host: <%= ENV['DB_PORT_5432_TCP_ADDR'] %>
Version 2
fallback mode
Пока links работают по-старому только network_mode: bridge.
# docker-compose.yml version: '2' services: app: build: . ports: - '3000:3000' volumes: - .:/home/web depends_on: - db links: - db network_mode: bridge db: image: sameersbn/postgresql ports: - '5432' volumes: - db_data:/var/lib/postgresql env_file: - $HOME/.docker/$APP/db.env network_mode: bridge volumes: db_data:
# config/database.yml development: adapter: postgresql encoding: unicode database: <%= ENV['DB_ENV_DB_NAME'] %> pool: 5 username: <%= ENV['DB_ENV_DB_USER'] %> password: <%= ENV['DB_ENV_DB_PASS'] %> host: <%= ENV['DB_PORT_5432_TCP_ADDR'] %>
Без links, но используя env file.
# docker-compose.yml version: '2' services: app: build: . ports: - '3000:3000' volumes: - .:/home/web depends_on: - db env_file: - $HOME/.docker/$APP/db.env db: image: sameersbn/postgresql ports: - '5432' volumes: - db_data:/var/lib/postgresql env_file: - $HOME/.docker/$APP/db.env volumes: db_data:
# config/database.yml development: adapter: postgresql encoding: unicode database: <%= ENV['DB_NAME'] %> pool: 5 username: <%= ENV['DB_USER'] %> password: <%= ENV['DB_PASS'] %> host: <%= ENV['DB_HOST'] %>
# $HOME/.docker/$APP/db.env DB_NAME=habrahabr DB_USER=habrahabr DB_PASS=habrahabr DB_HOST=db
