This refactoring allows us to raise an error when there is no 'file' key specified in the .yml and no self.filename set. This error was specific to the tests, as the tests are the only place that constructs service dicts without sometimes setting a filename. Moving the function within the class as well as it is code that is exclusively for the use of validating properties for the ServiceLoader class.

Docker Compose
(Previously known as Fig)
Compose is a tool for defining and running multi-container 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.
- Define your app's environment with a
Dockerfileso it can be reproduced anywhere. - Define the services that make up your app in
docker-compose.ymlso they can be run together in an isolated environment: - Lastly, run
docker-compose upand 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
Installation and documentation
- Full documentation is available on Docker's website.
