Create and operate CloudNativePG (CNPG) Postgres databases on Kubernetes the GitOps/Flux way - on managed cloud (GKE + GCS via Workload Identity) OR self-hosted (K3s/bare-metal + any S3-compatible store via a credentials secret). Covers Cluster + ScheduledBackup manifests, barman WAL archiving, pgvector, PITR, prod→dev clones, and the NetworkPolicies a default-deny cluster needs. Use when provisioning a new app database, cloning prod into dev, enabling pgvector, wiring backups/PITR, writing…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# cnpg Provision and run CloudNativePG (CNPG) Postgres on Kubernetes as GitOps. Every concrete identifier below is a placeholder - substitute your own: `<project>`, `<gcp-sa>`, `<backups-bucket>`, `<cluster>`, `<ns>`, `<svc>`, `<db>`, `<owner>`, `<env>`, `<s3-endpoint>`, `<objstore-secret>`, `<app-ns>`. **Two platforms, one operator.** The Cluster spec, bootstrap, pgvector, PITR, clone, and most gotchas are identical everywhere; only **backup auth** and **NetworkPolicy** differ. Managed cloud (GKE + GCS): Workload Identity, no keys - steps below default to this. Self-hosted (K3s / bare-metal + S3-compatible store: MinIO, Ceph, R2, B2): an access-key Secret, plus explicit NetworkPolicies on a default-deny cluster. Read **`references/self-hosted-and-networkpolicy.md`** whenever there's no cloud Workload Identity or the cluster enforces default-deny. ## Mental model - two halves that MUST share one string A CNPG database is two halves agreeing on exactly one string, `<ns>/<cluster>`: the **GitOps half** - a CNPG `Cluster` whose `serviceAccountTemplate` annotation points the auto-created **pod KSA** (named after the **cluster**) at the GCP …

How to install
mdr add vanducng/skills/cnpg@sha256:46cf623d62f6217cThe line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
