pgAdmin is a web-based PostgreSQL database management tool. To run it in Docker Compose, add the following snippet to your docker-compose.yml:

  pgadmin:
    image: "dpage/pgadmin4:latest"
    environment:
      PGADMIN_DEFAULT_EMAIL: admin@example.com
      PGADMIN_DEFAULT_PASSWORD: password
      PGADMIN_LISTEN_ADDRESS: "127.0.0.1"
      PGADMIN_LISTEN_PORT: 5050
    network_mode: host

• Replace latest with a version number that is compatible with your Postgres version, e.g. 6.12.
