[Mysteri0K1ng]

Goal

Complete Lab 10 by publishing the QuickNotes Docker image to GHCR through a tag-triggered release workflow and deploying the released image to Hugging Face Spaces.

Changes

• Added a tag-triggered GitHub Actions release workflow for QuickNotes.
• Configured the workflow to build from app/ and push to GHCR with both v0.1.2 and latest tags.
• Used minimal workflow permissions with contents: read and packages: write.
• Added Hugging Face Space artifacts under cloud/hf-space/.
• Deployed QuickNotes to a public Hugging Face Space using the Docker SDK and app_port: 8080.
• Added Lab 10 measurement artifacts for GHCR/HF/Cloudflare evidence.
• Documented GHCR pull evidence, HF public health check, warm/cold latency measurements, design questions, and the Cloudflare Tunnel bonus in submissions/lab10.md.

Testing

Triggered the release workflow using tag v0.1.2 and confirmed the GHCR image was pushed successfully. Verified clean pulls for both ghcr.io/mysteri0k1ng/devops-intro/quicknotes:v0.1.2 and ghcr.io/mysteri0k1ng/devops-intro/quicknotes:latest. Deployed the same released image to Hugging Face Spaces and confirmed /health returned HTTP 200 with QuickNotes JSON. Measured Hugging Face warm latency and three cold-start requests after idle windows. For the bonus, exposed the local QuickNotes service through Cloudflare Tunnel, verified public access, measured 50 warm requests, and compared p50/p95 latency with Hugging Face Spaces.
