Docker Compose
Docker Compose is a method for creating containers through configuration files.
Contents
Installation
Most Linux distributions offer a docker-compose package.
Configuration
Compose Files
Volumes
Docker supports two methods for binding volumes, hereafter referred to as the 'long syntax' and the 'short syntax'. Docker Compose supports two parallel methods. Upstream recommendation is to use the long syntax.
The long syntax is as follows:
container_name: CONTAINER
version: 0.1
services:
web:
image: IMAGE
volumes:
- type: bind
source: relative/source/path
target: /absolute/target/path
read only: trueThe short syntax is as follows:
container_name: CONTAINER
version: 0.1
services:
web:
image: IMAGE
volumes:
- relative/source/path:/absolute/target/path:ro
Port Management
To give a container access to ports, use:
container_name: CONTAINER
version: 0.1
services:
web:
image: IMAGE
ports:
- 8888:8888
Environment Variables
To pass in an environment variable from the local environment to a Docker container, use:
container_name: CONTAINER
version: 0.1
services:
web:
image: IMAGE
environment:
- VARIABLE1
- VARIABLE2
