Dev Container + Cloudflare Tunnel Boilerplate

Monorepo example:

• NestJS API (backend submodule, default port 4242 via APP_PORT)
• NextJS web (frontend submodule, port 3003)
• Postgres (5432) + Adminer (8080) + Mailcatcher UI (1080) in .devcontainer/docker-compose.yml

Quick start (VS Code)

1. Open repo in VS Code
2. Cmd + Shift + P > Dev Containers: Reopen in Container
3. Wait for the initial dependency bootstrap to finish for both backend/ and frontend/
4. Verify local endpoints:

   curl -I http://localhost:3003
   curl -I http://localhost:4242
   curl -I http://localhost:8080

Cloudflare Tunnel

Tunnel runs as a separate cloudflared service in .devcontainer/docker-compose.yml. Set CLOUDFLARED_TOKEN in .devcontainer/.env to enable it.

See docs/CONTAINERS-DEMO.md for presentation script and rollout notes.
