This app is designed for use with VSCode Dev Containers.
First, create the env file at /docker/.env, and paste the following, making sure to provide a valid Riot API Key.
POSTGRES_USERNAME=postgres
POSTGRES_PASSWORD=password
REDIS_URL=redis://bandleglass_redis:6379
RIOT_API_KEY=YOUR_API_KEY_HERE
Ensure the "Dev Containers" extension is installed, then navigate to the project's root directory. Use Cmd/Ctrl + Shift + P to open up the Command Palette and select "Dev Containers: Reopen in Container".
In the container, use rails s -b 0.0.0.0 to start up the server, which can be accessed from your browser at https://localhost:3000/.
