A minimal Docker app: one interactive star field. Stars fly toward your cursor; click to reverse and they spew from the cursor like a firehose. Click again to switch back. Purely pointless, purely fun.

Every click is logged on the server so you can see usage in the log:

• On each click the app sends a GET request to /_log?stars=N&mode=in|out.
• stars = current star count when the user clicked.
• mode = in (stars moving toward cursor) or out (firehose from cursor).

Nginx returns 204 for /_log and logs each request. View interactivity with the usual container log:

docker logs -f pointless-interactive-web

Each click appears as a request line, e.g. "GET /_log?stars=220&mode=out HTTP/1.1" 204.

Run from GHCR (after CI pushes on main):

docker run -d -p 8080:80 --name pointless-interactive-web ghcr.io/<owner>/pointless-docker:latest

Build locally:

docker build -t pointless-web:latest .
docker run -d -p 8080:80 --name pointless-interactive-web pointless-web:latest

Open http://localhost:8080.

Launcher script:

chmod +x pointlessdocker
./pointlessdocker

Starts the container (if needed) and opens the app in your browser.

Pushes to main trigger a GitHub Actions workflow that builds the image and pushes it to GitHub Container Registry (ghcr.io). The workflow is in .github/workflows/docker-publish.yml. Image name: ghcr.io/<owner>/pointless-docker:latest (and a tag with the short SHA).

• Base image: nginx:alpine
• Frontend: one HTML page, one CSS file, one JS file (vanilla Canvas)
• Logging: GET /_log?stars=N&mode=in|out → nginx access log
