yeah, thats still not easy (or trivial, its not hard) for larger projects. I use environment variables for smaller projects, i have predefined environment variables for the images that get substituted for the real thing by docker compose, which in turn uses environment variables (here is an example: https://github.com/intellimate/Server/blob/master/image/compose/production.yml https://github.com/intellimate/Server/blob/master/image/comp...). For larger projects i would use docker-swarm or kubernets, they have their own solution.
