Literally any change in your system can break. It matters what you do once it breaks, and what I describe makes the whole thing much more repeatable and easier to recover from. Docker containers builds are extremely repeatable. You run some software called Artifactory, which keeps the built versions of your artifacts, including base image tags. You store your applications in there, as well as the Docker containers that you built. If you need to go back a version, you pull it out of Artifactory. This is industry standard at this point.
