docker-compose-gen

Generate docker-compose config segments dynamically.

Primary Use Case

It can be helpful to replace the default network with an externally defined one dynamically at time of orchestration.

docker-compose-gen can be used like so to make the default network containers are connected to an already defined network called lab.

docker-compose -f docker-compose.yml -f <(docker-compose-gen network --compose-version 3.1 --external lab) up
