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"
