Owner

Stand up CloudNativePG as the shared Postgres operator for app workloads on the k3s cluster, and deploy Umami as its first tenant.

Why

Current state: exactly one Postgres in the cluster - postgres:17 running inside the forgejo deployment (deploy/forgejo.yml:99). Everything else is SQLite (2fauth, etc.). Umami (the picked web-analytics tool) needs Postgres and would be the second Postgres-needing app, with GlitchTip a possible third. This is the moment to set the pattern before it sprawls.

Decision: do NOT graft new apps onto forgejo's in-pod Postgres - that couples blast radius and upgrade timing to the source-of-truth git server. Instead run a declarative operator that gives each app its own database/role in one managed cluster.

Scope

Deploy CloudNativePG operator to the k3s cluster
Define a shared apps Postgres Cluster CR (sizing for a homelab single node)
Wire backups to S3 (fits the existing AWS posture) via the operator's barman/object-store support
Provision a umami database + role
Deploy Umami pointed at it (cookieless web analytics for coilysiren.me surfaces)
Reverse-proxy the Umami tracking endpoint under coilysiren.me (ad-blocker resilience)

Stand up [CloudNativePG](https://cloudnative-pg.io/) as the shared Postgres operator for app workloads on the k3s cluster, and deploy Umami as its first tenant. ## Why Current state: exactly one Postgres in the cluster - `postgres:17` running *inside* the forgejo deployment (`deploy/forgejo.yml:99`). Everything else is SQLite (2fauth, etc.). Umami (the picked web-analytics tool) needs Postgres and would be the second Postgres-needing app, with GlitchTip a possible third. This is the moment to set the pattern before it sprawls. Decision: do NOT graft new apps onto forgejo's in-pod Postgres - that couples blast radius and upgrade timing to the source-of-truth git server. Instead run a declarative operator that gives each app its own database/role in one managed cluster. ## Scope - [ ] Deploy CloudNativePG operator to the k3s cluster - [ ] Define a shared `apps` Postgres Cluster CR (sizing for a homelab single node) - [ ] Wire backups to S3 (fits the existing AWS posture) via the operator's barman/object-store support - [ ] Provision a `umami` database + role - [ ] Deploy Umami pointed at it (cookieless web analytics for coilysiren.me surfaces) - [ ] Reverse-proxy the Umami tracking endpoint under coilysiren.me (ad-blocker resilience) ## Refs - Parent backlog: https://forgejo.coilysiren.me/coilyco-flight-deck/infrastructure/issues/326
