Host it yourself

1. Compile the server for the musl target. See the musl_build.sh for a way to do this trivially with Docker!
2. See Dockerfile for a simple alpine based image that runs that server binary.
3. Deploy the image where ever you want.

Testing Locally

# Run the Server: xpects TCP traffic on 8080 and control websockets on 5000
ALLOWED_HOSTS="localhost" cargo run --bin portal_server

# Run a local portal client talking to your local portal_server
CTRL_HOST="localhost" CTRL_PORT=5000 CTRL_TLS_OFF=1 cargo run --bin portal -- -p 8000

# Test it out!
# Remember 8080 is our local portal TCP server
curl -H 'Host: <subdomain>.localhost' "http://localhost:8080/some_path?with=somequery"

See portal_server/src/config.rs for the environment variables for configuration.
