At the risk of sounding very naïve and making huge guesses, what you describe seems to be what docker-compose solves. Special order of services, launching several containers at once. However, I have seen my fair share of oddities in the trenches where containers are evolution of virtual machines(vagrant) running everything in one vm but now split out into containers without adapting to how containers work, because new tech lead thought vms were uncool and everything must be docker now.
