Deploy on DigitalOcean App Platform

From the GitHub UI

1. In the DigitalOcean control panel, open Apps → Create App.
2. Connect GitHub and choose this repository and branch (main).
3. App Platform should detect the Dockerfile at the repo root. Confirm:
   • HTTP port: 8000 (matches EXPOSE in the Dockerfile and http_port in app.yaml).
4. Create the app and wait for the first deploy.

From an app spec (app.yaml)

1. Fork or clone the repo and push it to a GitHub account that DigitalOcean can access.

2. Edit app.yaml and set services[0].github.repo to your GitHub repo (for example your-user/rust-chess).

3. Install doctl, run doctl auth init, then:

   doctl apps create --spec app.yaml

   To update an existing app, use doctl apps update <app-id> --spec app.yaml.

Notes

• PORT: The server reads PORT from the environment (default 8000). The sample app.yaml sets PORT=8000 for clarity; App Platform also injects PORT when routing HTTP to your container.
• Single instance: Game state is in memory. Use one instance (as in app.yaml) unless you add shared storage and redesign session affinity.

Run locally

cargo run --release

Open http://127.0.0.1:8000. Override the port with PORT=3000 cargo run --release if you like.
