Walkthrough

Adds containerization and CI/CD: a multi-stage Dockerfile to build a web renderer and serve via Nginx, a docker-compose.yml to run the app locally, and a GitHub Actions workflow to build and push the Docker image to Docker Hub on pushes/PRs to main.

Changes

Cohort / File(s)	Summary of Changes
CI/CD Workflow .github/workflows/docker-publish.yml	New workflow “Docker Image CI” triggered on push/PR to main; checks out code, logs into Docker Hub via secrets, builds and pushes image using docker/build-push-action@v5 to highkay/chatbox-web:latest.
Container Image Build Dockerfile	New multi-stage Dockerfile: Node 22-alpine base, install deps from npmmirror, build with npm run build:web, final stage on nginx:alpine serving artifacts from /app/release/app/dist/renderer at port 80.
Local Orchestration docker-compose.yml	New Compose v3.8 file with service “chatbox” built from current dir, port mapping 3000:3000, and volume ./data to /root/.config/xyz.chatboxapp.ce.

Poem

Hop hop! I baked a shiny ship,
Docker clouds for every trip.
Actions push it, swift and clean,
Nginx hums with static sheen.
Compose says “up!”—ports align,
A warren of bits, deployed just fine.
Carrots for logs; all green! 🥕🚀
