Media preview stack
The release coordinator at fictional Lumen Media needs a local preview stack. The supplied page is original fixture content. Deliver a versioned web image, a dedicated bridge, a persistent cache volume, the two running services and a saved inventory. Keep unrelated workspace files.
A media producer needs a repeatable preview environment with a web process and a cache. You'll build its release image, prepare the storage and network boundaries, then start each process with the requested configuration. Every step retains your earlier state. The final handoff includes a process inventory so the next operator can identify the exact running services. This local project creates no real containers or external infrastructure. Treat host content and cache data differently: one belongs to the editor's workspace, while the other should survive replacement of its container. Check the application paths and connection names before moving to the handoff.

A worked first action on this original project fixture.
