Docker Compose
|
|
==============
|
|
*(Previously known as Fig)*
|
|
|
|
Compose is a tool for defining and running complex applications with Docker.
|
|
With Compose, you define a multi-container application in a single file, then
|
|
spin your application up in a single command which does everything that needs to
|
|
be done to get it running.
|
|
|
|
Compose is great for development environments, staging servers, and CI. We don't
|
|
recommend that you use it in production yet.
|
|
|
|
Using Compose is basically a three-step process.
|
|
|
|
1. Define your app's environment with a `Dockerfile` so it can be
|
|
reproduced anywhere.
|
|
2. Define the services that make up your app in `docker-compose.yml` so
|
|
they can be run together in an isolated environment:
|
|
3. Lastly, run `docker-compose up` and Compose will start and run your entire app.
|
|
|
|
A `docker-compose.yml` looks like this:
|
|
|
|
web:
|
|
build: .
|
|
ports:
|
|
- "5000:5000"
|
|
volumes:
|
|
- .:/code
|
|
links:
|
|
- redis
|
|
redis:
|
|
image: redis
|
|
|
|
Compose has commands for managing the whole lifecycle of your application:
|
|
|
|
* Start, stop and rebuild services
|
|
* View the status of running services
|
|
* Stream the log output of running services
|
|
* Run a one-off command on a service
|
