GitHub user elhimad edited a discussion: Keldon — Kubernetes Operator for Apache Cloudberry (looking for feedback)
Hi everyone, I've been building **Keldon**, an open-source Kubernetes operator for Apache Cloudberry, and just shipped the first public release (v0.11.1). **What it does:** - Fully automated cluster bootstrap via `gpinitsystem` — coordinator, standby, segments, and mirrors, all provisioned declaratively from a single YAML - Horizontal scale-up: patch `spec.segments.count`, the operator provisions new pods and redistributes data automatically - Two SSH trust models: static keypair for dev/CI, certificate mode for production (per-cluster CA, short-lived certs, annotation-driven rotation without pod restarts) - Declarative `postgresql.conf` and `pg_hba.conf` management via `DatabaseConfig` - High availability out of the box: standby coordinator (WAL streaming, auto-promoted on failure) and mirror segments (one mirror per primary, auto-recovered via `gprecoverseg`) - On-demand backups to S3-compatible storage via `gpbackup`, with cross-cluster restore support - Phase-driven lifecycle: `PodsStarting` → `SSHReady` → `Initializing` → `Running`, with the operator reconciling continuously from there - Admission webhook that catches errors at the API boundary — cluster name length, HA node availability, invalid CRD references — before anything reaches a pod - Helm install, cert-manager for webhook TLS, Kubernetes 1.29+ **Why I built it:** Standing up a Cloudberry cluster is operationally heavy — SSH trust, gpinitsystem, segment registration, mirror setup, replication wiring. Keldon automates all of it so you can go from zero to a running MPP cluster without touching any of it manually. **What I'm looking for:** 1. Are there use cases or deployment patterns in the community I haven't accounted for? 2. Anything in the way Keldon models clusters that conflicts with how you think about Cloudberry architecture? 3. If you get a chance to try it, I'd love to hear what breaks — missing features / bug to fix Repo: [github.com/keldonio/keldon-operator](https://github.com/keldonio/keldon-operator) Docs: [keldon.io/docs](https://keldon.io/docs) Happy to answer questions or take direction on anything missing. — Imad GitHub link: https://github.com/apache/cloudberry/discussions/1838 ---- This is an automatically sent email for [email protected].
