To be fair, pretty much every single place I've seen docker in use there have been custom automation systems in place. Docker creates artifacts, not automation, so it really doesn't help solve that problem. Kubernetes on the other hand, does help, though you'll never get away from some custom parts in a delivery system, as all systems are different. That's not a bad thing.
