Branch
This branch is an execution lane inside Virtualization and Containers: closely related guides, builds, and validation work that should stay clustered instead of scattering across the library.
Build one complete GitHub Actions pipeline for a disposable Docker service: test, build, publish a versioned image, deploy it, deliberately fail the new version, and roll back to the previous digest/tag.
Deploy Nginx Proxy Manager with persistent data, route one disposable backend through a real hostname, and validate HTTP-to-HTTPS behavior plus certificate issuance without exposing the admin interface unnecessarily.
Build a maintainable Raspberry Pi container host with Docker Engine, the current Compose plugin, service health checks, and a controlled update workflow.
