This is minimal disruptive change I could make to ensure the service integration tests worked, now we have some validation happening. There is some coupling/entanglement/assumption going on here. Project when creating a service, using it's class method from_dicts performs some transformations on links, net & volume_from, which get passed on to Service when creating. Service itself, then performs some transformation on those values. This worked fine in the tests before because those options were merely passed on via make_service_dict. This is no longer true with our validation in place. You can't pass to ServiceLoader [(obj, 'string')] for links, the validation expects it to be a list of strings. Which it would be when passed into Project.from_dicts method. I think the tests need some re-factoring but for now, manually deleting keys out of the kwargs and then putting them back in for Service Creation allows the tests to continue. I am not super happy about this approach. Hopefully we can come back and improve it. Signed-off-by: Mazz Mosley <mazz@houseofmnowster.com>
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.
- 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.
