Run, configure, upgrade and troubleshoot the Zalando postgres-operator (acid.zalan.do `postgresql` CRs, Spilo, Patroni, WAL-G) on Kubernetes. Core knowledge: the v1.x -> v2.x major upgrade and its three changed defaults that bite silently (`kubernetes_use_configmaps` true, spilo-17 -> spilo-18, scram-sha-256 password encryption); the Patroni DCS living in deprecated v1 Endpoints and the split-brain hazard in switching to ConfigMaps; Helm never updating the CRDs; exactly which spec changes…
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
# postgres-operator-best-practices Operate the Zalando postgres-operator without surprise downtime. Facts below hold at upstream tag `v2.0.3` (`docs/administrator.md`, `docs/migrate.md`, chart defaults); citations and check dates are in `references/sources.md`. Re-verify anything version-gated before relying on it. **Version anchor:** v1.14.0 (2024-12-23) · **v1.15.0** (2025-10-21, ships without UI and logical-backup images — never use it, go to v1.15.1) · **v1.15.1** (2025-12-18) · v2.0.0 (2026-07-27) · v2.0.1 (2026-07-29) · v2.0.2 (2026-08-20) · **v2.0.3** (2026-10-02, current). Default Spilo: `spilo-17:4.0-p2` in v1.14.0, `spilo-17:4.0-p3` in v1.15.1, `spilo-18:4.1-p2` in v2.0.x (the v2.0.3 release notes print `spilo-17:4.1-p2`; the chart and code say `spilo-18`). For migrating away to CloudNativePG, and for the "is this project still alive" evidence, use `postgres-operator-cloudnative-pg-migration`. This skill assumes the decision is to stay. ## Symptom index | Symptom | Where | |---|---| | Unknown-field errors after a chart bump; config options silently ignored | §1 below — Helm does not update the CRDs | …

How to install
mdr add air-gapped/skills/postgres-operator-best-practices@sha256:4ad34ac46eb4bde4The line at the top of this page pins the label git:20261027.5cdb26e, 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.
