ServiceLoader has evolved to be not really all that related to "loading" a service. It's responsibility is more to do with handling the `extends` field, which is only part of loading. The class and its primary method (make_service_dict()) were renamed to better reflect their responsibility. As part of that change process_container_options() was removed from make_service_dict() and renamed to process_service(). It contains logic for handling the non-extends options. This change allows us to remove the hacks from testcase.py and only call the functions we need to format a service dict correctly for integration tests.

Docker Compose
Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application's services. Then, using a single command, you create and start all the services from your configuration. To learn more about all the features of Compose see the list of features.
Compose is great for development, testing, and staging environments, as well as CI workflows. You can learn more about each case in Common Use Cases.
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
For more information about the Compose file, see the Compose file reference
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.
- If you have any questions, you can talk in real-time with other developers in the #docker-compose IRC channel on Freenode. Click here to join using IRCCloud.
