This is good and interesting recipe to get Keycloak and Postgres on Kubernetes.

There is an important improvement, though: the Postgres deployed here is not production ready (high availability, backups, monitoring, etc).

We run Keycloak on StackGres [1] which gives us production-ready Postgres setup (disclaimer: it's dogfooding). Happy to share the YAML manifests used to deploy Keycloak with StackGres. Maybe we will write a blog post as a follow-up to this one, for completeness.
