your volume example is an anti-pattern in regard to something like the 12 factor app. you're conditionally changing and setting the volumes based on an environment your in? your code and service is gonna be busted. how would you even know if anything worked in prod if it's not reproducible in dev since # if dev then volume xyz else volume abc #

It's an anti-pattern just because you say so. This is a simplified example of a complex problem that needs arbitrary volume mounts. Using volume mounts to run software inside containers is a common dev pattern on scenarios where rebuilding takes too much time to quickly iterate. I am sorry, but unfortunately I cannot expand the issue further here to help you understand it, and I am happy too if you think I am over-engineering compose.

I honestly don't care if it's you misunderstanding or your teammates are building a bad framework/foundation to iterate upon. Doesn't matter to me either way bud. But you're going against the premise of docker and docker-compose which is write once and run anywhere because the services will be different every time you deploy since they'll have have variable path and file locations etc. - that's why it's an anti-pattern not because "i say so"
