Pull Request Checklist

I have read and followed the CONTRIBUTING.md guidelines.
I have read and followed the Guidance for submissions involving paid services.
My contribution adds a new instruction, prompt, agent, skill, workflow, or canvas extension file in the correct directory.
The file follows the required naming convention.
The content is clearly structured and follows the example format.
I have tested my instructions, prompt, agent, skill, workflow, or canvas extension with GitHub Copilot.
I have run npm start and verified that README.md is up to date.
I am targeting the main branch for this pull request.

Description

Update the approved Containers listing to 0.1.2 and replace its icon-only extension preview with real app screenshots. The summary now covers Docker, Podman, and Compose. External extension pages render the owning plugin's pinned README, so the page includes features, quickstart, requirements, and usage-data information.

Registered external canvas plugins can declare a gallery in extensions/external.json without duplicating their version, source, or install identity. The logo remains a small icon instead of an enlarged gallery image. README retrieval and sanitization reuse the existing plugin-page implementation; raw Markdown stays out of catalog hydration.

Preview asset: native Containers 0.1.2 with sample containers.

Type of Contribution

New instruction file.
New prompt file.
New agent file.
New plugin.
New skill file.
New agentic workflow.
New canvas extension.
Update to existing instruction, prompt, agent, plugin, skill, workflow, or canvas extension.
Other (please specify): external-extension website presentation and README integration.

Additional Notes

Release qualification limit: native testing is incomplete. A real Podman qualification stalled during provider startup. Two live run_image operations created their containers but did not return before interruption. The source suite, browser regressions, and installed behavior/CSP checks passed, but this PR does not claim that those live-call hangs are fixed or that native qualification is complete.

Local website build limit: Astro emitted 1,599 pages and reported completion. The enclosing Windows build command did not exit before its four-minute deadline and was stopped. Focused generated-page, browser, and accessibility checks passed against the emitted site.

Release provenance and focused validation

Production artifact: microsoft/azure-dev-tools#95.
Awesome Copilot source.sha: 79f3fa46520ceaefa1c9c863c92f05912c1f2f0f.
Immutable release ref: containers-v0-1-2-7b8c7ff.
Latest canvas: containers-latest.
Retained CI package SHA-256: 6eb9c200ace685a8522315f183c3866d96b6ae7ab5e92dde83eb5d04ba4b9834. The package was not rebuilt or changed for this submission.
Fifteen gallery and pinned-README retrieval checks passed.
Thirty-five generated-page, Markdown/image-provenance, sanitization, and install-URI checks passed.
Plugin validation passed for 110 local plugins and 97 external listings; three existing license warnings remain.
The built Containers page passed light/dark checks at 1440px and 390px, including three loaded app screenshots, a separate 32px icon, install-link identity, document overflow, renderer errors, and critical/serious WCAG findings.
Earlier release checks passed 244 source tests, 23 browser tests, and the installed behavior/CSP exercise. The stock packaged-inventory test rejects the promotion's additional SHA256SUMS receipt; that mismatch remains unresolved.
No package deployment, rollout announcement, or merge is included.

By submitting this pull request, I confirm that my contribution abides by the Code of Conduct and will be licensed under the MIT License.

Removing a plugin leaves its gallery override behind, causing subsequent website data generation to fail and blocking deployment.

I'm a little apprehensive about combining the two different things within this one PR, as the update to the Containers extension shouldn't be blocked by the following comments/feedback.

I'll be honest that I forgot we had the extensions/external.json file still in the repo, and in reality it should be removed as it's a holdover from a time before we used Plugins as the distribution method for extensions (canvases). Also, as you can probably see, there's only two items in there so it's not really used.

I don't think that putting the screenshots required for the gallery for external canvases in the Awesome Copilot repo is the best workflow. It means that there are now two places that assets for a canvas (well, plugin really) need to live, rather than Awesome Copilot acting as a pointer to the upstream.

We could expand the plugins/external.json to have support for providing screenshots, and make it work relative to the ref/sha and path provided for that plugin, or we could have the website build query the upstream plugin.json and look in its extensions property for maybe a com.github.awesome-copilot folder in which we have that structure for images with their descriptions.

There's pros and cons for both, putting the gallery info in the external.json means that the PR has the potential for requiring a bit more complexity in authoring, whereas reading the upstream plugin.json increases website build time. As an author who wants to expand their canvases gallery feature, what would you prefer?
