Operate self-managed GitLab on the official Helm chart — multi-hop upgrade campaigns across required stops, the chart-10 wall (bundled PostgreSQL, Redis and MinIO removed and now mandatory), PostgreSQL 17 being both the minimum and the maximum for GitLab 19.x, default flips invisible to a values diff, air-gapped image sets the chart will not reveal, backup/restore with external dependencies and the secrets that are deliberately not in the backup, Sidekiq migration-loss and HPA-flap traps, and…
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
# gitlab-best-practices Run and upgrade a **self-managed GitLab on the official Helm chart** without unplanned downtime. The hard part is never `helm upgrade`. It is that the chart changes defaults the site never set, ships prerequisites written for a configuration the site does not run, and removed its own bundled databases in a release that breaks the *tooling* before it breaks the deployment. Facts here were verified **2026-08-29** against machine-readable upstream sources, the unpacked chart, and hands-on upgrade tests. Re-verify anything version-bearing. **Version anchor (2026-08-29):** latest chart **10.3.1** / app **19.3.1**. Chart major = app major − 9. Required stops through 19.x: **18.2 · 18.5 · 18.8 · 18.11 · 19.2 · 19.5 · 19.8 · 19.11** — enumerate them fresh, never from memory. ## Symptom index | Symptom | Where | |---|---| | Planning a multi-version upgrade; which stops, which order | § The ladder below, then `references/upgrade-campaign.md` | | Ingress objects gone after a chart bump; instance off the network | `references/upgrade-campaign.md` § the chart-10 wall | …

How to install
mdr add air-gapped/skills/gitlab-best-practices@sha256:41004078f9fe8b38The line at the top of this page pins the label git:20261027.4b5fb58, 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.
