Docker doesn't imply not having config management. In fact for our infrastructure that was using puppet to build vms, we just run puppet as part of `docker build` instead. Still using config management and our prod, staging and dev environments run the same exact blobs.

Sometimes; and tools like Ansible Container can help have the best of both worlds.
But for every time I see someone using actual configuration management and best practices for reproducible Docker architecture, I see a hundred times when there are brittle and convoluted shell scripts or worse, entire application definitions in a 500+ line Dockerfile (which is neither configuration management nor scripts. At least the scripts are somewhat more portable and maintainable!)
