Pin Upstream Images

What it does

This skill automates pinning container image SHA tags used by the multigres operator (multigres, pgctld, multiadmin-web). It fetches latest SHA tags, updates api/v1alpha1/image_defaults.go, and performs an upstream code comparison to identify commits that might affect operator compatibility. The workflow includes fetching SHAs, updating image_defaults.go, running git diffs between old and new SHAs, and producing an evidence-backed impact analysis.

When to use it

Use this skill when preparing an operator release or bumping image tags: e.g., "prepare images for release", "pin image tags", or "upgrade multigres images". Run it before publishing a release so you can audit breaking changes, flag required operator updates, and generate a precise commit message.

What's included

• Scripts: fetch_latest_tags.py (has_scripts=true)
• References: none listed
• Instructions: step-by-step guidance to fetch SHAs, update image_defaults.go, clone upstream monorepo for diffs, filter non-binary changes, and run flag/env audits against operator containers. The skill prescribes per-container checks for flags and environment variables and a final smoke test flow.

Compatible agents

Compatible with command-line-capable agents and CI automation that can run Python and git (e.g., Codex/GitHub runner, CLI-based agents).
