Docker

The docker feature brings docker and docker-compose integration. You may also check Jsonnet Feature, as using jsonnet docker specific library brings many Docker related features to ddb.

docker-compose configuration processing

When a docker-compose.yml is found or generated from templates, the content is parsed.

All labels prefixed ddb.emit. are processed and converted into event and event arguments.

Creation of binaries

Whether you use ddb.Binary() in jsonnet template or manually add labels to docker-compose.yml, they are converted into ddb configuration and shims are generated to run the declared binary as simple executable command, thanks to shell feature.
