I am trying to install Dgrpha with Docker in different ports.And Zeros are working but alphas are not.Just like this

```auto
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7628dbc67369 dgraph/dgraph:latest "dgraph alpha --my=a…" 39 seconds ago Restarting (1) Less than a second ago server_alpha_law_1
be3f22a347ce dgraph/dgraph:latest "dgraph-ratel" 39 seconds ago Up 38 seconds 8080/tcp, 0.0.0.0:8001->8001/tcp, 9080/tcp server_ratel_law_1
0d5a8c560e68 dgraph/dgraph:latest "dgraph zero --my=ze…" 39 seconds ago Up 37 seconds 0.0.0.0:5081->5081/tcp, 8080/tcp, 0.0.0.0:6081->6081/tcp, 9080/tcp server_zero_law_1

```

And compose.yaml

```auto
version: "3.2"
services:
  zero_info:
    image: dgraph/dgraph:latest
    volumes:
      - /home/server/dgraph_data/info:/dgraph
    ports:
      - 5081:5081
      - 6081:6081
    restart: on-failure
    command: dgraph zero --my=zero_info:5080 -o 1
  alpha_info:
    image: dgraph/dgraph:latest
    volumes:
      - /home/server/dgraph_data/info:/dgraph
    ports:
      - 8081:8081
      - 9081:9081
    restart: on-failure
    command: dgraph alpha --my=alpha_info:7080 -o 1 --lru_mb=2048 --zero=zero_info:5080 -o 1
  ratel_info:
    image: dgraph/dgraph:latest
    ports:
      - 8001:8001
    command: dgraph-ratel

```

@Soultrans, The problem is with your `--my` flag. The my flag is not used to set the port. It is used to just let alpha know on what IP:port it is running so that it can be used by other nodes to communicate with this alpha.  
The port is set by the `-o` (offset) flag.  
So, setting `-o 1` means the port is `default port + 1`

```auto
version: "3.2"
services:
  zero_info:
    image: dgraph/dgraph:latest
    volumes:
      - /home/server/dgraph_data/info:/dgraph
    ports:
      - 5081:5081
      - 6081:6081
    restart: on-failure
    command: dgraph zero --my=zero_info:5081 -o 1
  alpha_info:
    image: dgraph/dgraph:latest
    volumes:
      - /home/server/dgraph_data/info:/dgraph
    ports:
      - 8081:8081
      - 9081:9081
    restart: on-failure
    command: dgraph alpha --my=alpha_info:7081 -o 1 --lru_mb=2048 --zero=zero_info:5081
  ratel_info:
    image: dgraph/dgraph:latest
    ports:
      - 8001:8001
    command: dgraph-ratel

```

Can you try using this config?
