dynamic docker-compose config from env

Is there a tool to dynamically set services, external_links, etc. for container orchestration, depending on an environment variable?

Tool should have convenient syntax (Python/js/bash - any clearly readable), and support conditions (if).

Now I have 3 files like docker-compose.local.yml, and edit them all.

cp docker-compose.local.yml docker-compose.yml;
docker-compose up;

I wan't one config file

ENV=local;
docker-compose up; # or "node start-compose.js"

I know that docker-compose supports environment variables like

volumes:
  - ${ENV}-filename:/.../filename

But I need more.

You can use .env files to store all your compose configuration.

Just as you do cp docker-compose.local.yml docker-compose.yml; You do cp local.env .env; docker-compose up will automatically pick up the .env file.

Taken from the docs Environment Variables in Compose
