Experiences with running PostgreSQL on Kubernetes
So they say it's hard to run it in Kubernetes because they weren't running it in StatefulSets. Then they say you can actually run it properly in a StatefulSet but hand-wave it away with "but people run it on top of Ceph which has issues with latency". That sounds like a shitty excuse to just dismiss the whole thing as too hard. If one particular underlying storage system wasn't good, use a better one. Kubernetes allows you to abstract the actual storage implementation to whatever you want so it's not like there's lack of options.Also I'd be curious to see if "most people" actually use Ceph vs network storage like EBS volumes where AWS guarantees me that I won't have data corruption issues in exchange for money.
