Get Expo working in a docker container

[delboy1978uk]

Ideally the node container Dockerfile should have node 24 (or whatever the current LTS is), nvm, & pnpm for the package manager.

I tried this before but I'm guessing some ports were not exposed and that's why the phone wouldn't connect after scanning the QR.

add a ./frontend` folder ad add it to the app container which does the mounts:

    app:
        image: httpd:2.4.38
        volumes:
            - ./code:/var/www/html
            - ./frontend:/frontend
        command: "echo true"

Start the stack:

./bin/start

Open a new terminal

./bin/terminal node
cd /frontend 
npx create-expo-app@latest
