where should I put docker-compose.yml
I'm asking myself the same question: Where to put my docker-compose.yml file?
I've decided to do it the following way:
- One Repo for the
docker-compose.ymlalong with deployment scripts (Jenkins pipeline in my case). - One Repo per micro service along with a Dockerfile and its build logic (built image is pushed to private docker registry).
Why?
- The
docker-compose.ymldescribes a system (the composition of micro services) and how it is deployed. - A micro services should be independent from the system infrastructure.
- There could be more than one system (different composition of the micro services) with a second
docker-compose.yml(and Repo).
However, of course there are reasonable exceptions.Assume you're deploying a customized Database along with a management tool (e.g. customized mariadb and adminer), then most things may live in one repository.
