> Having recently heard a lot of about PostgreSQL in Kubernetes

I could never get a straight answer on whether running a database in a container (and mounting the storage volume through a bind mount/network drive or whatever) came with a performance hit compared to running it as a systemd service for example.

It does but it’s minimal. Especially compared to the high latency and low throughout network volumes provides (which are the defaults on cloud VMs).

In case you are interested, I blogged about it last year: https://thenewstack.io/kubernetes-will-revolutionize-enterpr...

TL;DR performance impact should be negligible, could be even slightly negative compared to a VM (when running K8s on bare metal).

What's the best way to simply mount the storage volume needed for Postgres to be performant?
