What I want to do

Using community edition, I want to start zero, alpha and ratel

What I did

Here’s a part of my docker compose I am using

    image: dgraph/dgraph:latest
    volumes:
      - dgraph-data:/dgraph
    ports:
      - 5080:5080
      - 6080:6080
    networks:
      - aether_network
    restart: on-failure
    command: dgraph zero --my=zero:5080
