This is a failed attempt at getting my head around the structure for docker-compose for multiple environments.
The goals:
- Keep the environment-specific docker-compose configurations as small as possible (maximize reuse of configuration). (I started experimenting with using
.envfiles.) - Allow (non-swarm) servers to keep sensitive information outside of SCM, in a designated directory. (My thought was to use a
./vardirectory, which is in SCM, but which has its contents ignored.)
From the localdev directory, things behave as expected:
$ cd docker-compose/localdev/
$ docker-compose up --build -d
WARNING: The Docker Engine you're using is running in swarm mode.
Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.
To deploy your application across the swarm, use `docker stack deploy`.

From the test1 directory (which emulates how it would be run on the server), my attempts at factoring the environment-specific docker-compose.yml and/or the use of the remote .env file causes problems.
$ cd docker-compose/localdev/
$ docker-compose up --build -d
