SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and assets (resource) components.

What problem does it solve? Publishing a container image release involves many error-prone manual steps: preparing a changelog, creating a release branch, opening and merging a PR, tagging from the default branch, waiting for CI, and verifying the pushed image digest. This Skill orchestrates that entire release flow with strict guardrails so releases always start from a clean, synced default branch. ## Core Features & Use Cases - End-to-end release execution: Runs setup, prep, publish, or complete modes covering changelog prep, release branch creation, PR creation and merge, annotated tag push, workflow wait, and image digest verification. - Guardrailed Git operations: Refuses to prep or publish from feature branches or dirty worktrees, blocks force-pushes and branch-protection bypasses, and stops when human approvals are required. - Reusable setup assets: Generates changelog and release-helper script templates, delegating workflow YAML to the github-workflows skill. - Use Case: A maintainer asks to release version 1.2.0 of a service; the Skill creates release/myservice-v1.2.0, merges the prep PR, tags from the default branch, waits for the image workflow, and reports the verified image digest. ## Quick Start Use the publish-image skill to publish my container image end to end with --mode complete --tag 1.2.0 and report the verified digest.

Frequently Asked Questions about publish-image

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I publish a container image release end to end?▼

Run the skill with --mode complete --tag X.Y.Z from your project folder. It prepares the changelog on a release branch, creates and merges the PR, tags from the default branch, waits for the image workflow, and verifies the published digest.

How to tag and push a container image release from GitHub?▼

Use --mode publish from a clean, synced default branch. The helper script creates an annotated tag in the form prefix-vX.Y.Z and pushes it to origin, which triggers the tag-based image workflow.

Why does the release prep fail on my feature branch?▼

Prep and publish modes require the clean, synced default branch as the release source of truth. Merge your feature branch into the default branch first, switch to it, fast-forward, and rerun the command.

Can I verify a published image tag and digest?▼

Yes, use --mode verify --tag X.Y.Z --image-name your-registry/repo. The skill runs docker buildx imagetools inspect to confirm the tag exists and records the digest as release evidence.

Does this skill store registry credentials or secrets?▼

No, it stores only secret and variable names in templates and workflow files. Actual secret values stay in GitHub secrets, the local environment, or the registry login mechanism.
