StatefulSets were added to handle things like this. It always seemed like an afterthought to me, appeasing people trying to run things that Kubernetes was never designed to handle. At $BIG_CORP our executives became very excited about "The Cloud" and many teams were forced to migrate their applications over. Didn't matter if it was a proper 12 factor application or a monolithic vendor JAR that required 64GB of ram. You were punished for using VMs, so teams spent an inordinate amount of time shoving square pegs into round holes.
