This is a small library to load Docker Compose v3 YAML files for further consumption. The driving force is the Docker Client library, where the equivalent to docker stack deploy needs to load such Compose v3 YAML files.

A bit more clarification can be found at issue #2.

Given a Compose file being available as InputStream and its workingDir you can read the YAML file like this:

InputStream composeStack = getClass().getResourceAsStream('docker-stack.yml')
String workingDir = Paths.get(getClass().getResource('docker-stack.yml').toURI()).parent
ComposeConfig composeConfig = new ComposeFileReader().load(composeStack, workingDir, System.getenv())
...

You can find a real life example at the Docker Client's DeployConfigReader.

Please submit an issue if you'd like to ask a question or propose a new feature (maybe Compose v2 support?). Pull Requests are welcome, too!
