#1838 Keldon — Kubernetes Operator for Apache Cloudberry (looking for feedback) New discussion created by elhimad 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 Docs: keldon.io/docs Happy to answer questions or take direction on anything missing. — Imad apache/cloudberry
