Cannot get a distributed deployment to work on docker

Hi,

I’ve been trying to setup a dgraphzero and a dgraph instance on docker for about a day now, to no avail.

I get these errors:
zero_1 | 2017/11/04 13:45:39 pool.go:150: Echo error from 172.20.0.1:12345. Err: rpc error: code = Unavailable desc = grpc: the connection is unavailable

and,
dgraph_1 | 2017/11/04 01:26:09 groups.go:388: WARNING: We don't have address of any dgraphzero server.

and when I try to run a query on the dgraph instance I get this error:

{
  "errors": [
    {
      "code": "Error",
      "message": "No connection exists"
    }
  ],
  "data": null
}

Here is my compose file:

  zero:
    build: dgraph
    command: ['/opt/scripts/zero.sh']
    #volumes:
    #  - dgraphdata1:/dgraph
    ports:
      - 8888:8888
      - 8889:8889

  dgraph:
    build: dgraph
    command: ['/opt/scripts/dgraph.sh']
    #volumes:
    #  - dgraphdata1:/dgraph
    ports:
      - 8080:8080
      - 9080:9080

And my start scripts:

dgraph.sh

#!/bin/bash

IP=`ip route | awk '/default/ { print $3 }'`

dgraph \
  --bindall=true \
  --memory_mb 2048 \
  --my "$IP:12345" \
  --peer "zero:8888" \
  --workerport 12345

zero.sh

#!/bin/bash

IP=`ip route | awk '/default/ { print $3 }'`

dgraphzero \
  --bindall=true \
  --my "$IP:12345" \
  -w zw

Any help would be appreciated, thanks!

I’m not too familiar with docker compose files, but this looks a bit suspicious to me:

--peer "zero:8888" \

Try localhost instead of zero.

I ended solving this this way:

This is the problem. It should be port 8888.
