1. Create a Docker Compose file

Create an empty folder and, inside that folder, create a file named docker-compose.yml with the following content:

docker-compose.yml

services:
  db:
    image: postgres:14.5
    environment: &db-env
      POSTGRES_USER: postgresusername
      POSTGRES_PASSWORD: postgrespassword
    volumes:
      - dbdata:/var/lib/postgresql/data

  web:
    image: riggraz/astuto:latest
    environment:
      <<: *db-env
      BASE_URL: http://yourwebsite.com
      SECRET_KEY_BASE: yoursecretkeybase
    ports:
      - "3000:3000"
    depends_on:
      - db
    
volumes:
  dbdata:

2. Edit environment variables
