linting... six.string_types list-of-strings in examples disallow extra_hosts support for list-of-dicts A more thorough sets of tests for extra_hosts Provide better examples As per @aanand's [comment](https://github.com/docker/compose/pull/1158/files#r28326312) I think it'd be better to check `if not isinstance(extra_hosts_line, six.string_types)` and raise an error saying `extra_hosts_config must be either a list of strings or a string->string mapping`. We shouldn't need to do anything special with the list-of-dicts case. order result to work with assert use set() instead of sort() Signed-off-by: CJ <lim@chernjie.com> |

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.
First, you define your app's environment with a Dockerfile
so it can be
reproduced anywhere:
FROM python:2.7
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code
CMD python app.py
Next, you define the services that make up your app in docker-compose.yml
so
they can be run together in an isolated environment:
web:
build: .
links:
- db
ports:
- "8000:8000"
db:
image: postgres
Lastly, run docker-compose up
and Compose will start and run your entire app.
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
Installation and documentation
- Full documentation is available on Docker's website.
- Hop into #docker-compose on Freenode if you have any questions.
