I can do something like this? (Two Dgraphs in the same host, different ports)

Yes, you can definitely do that.

I’m not fluent with Kubernetes (looks like Kubernetes config) however I can see a few things that might be wrong.

The port offset for zeroapi and zeroTwo are both -2000, so there will be a port conflict. Try setting these different.

peter · December 11, 2017, 11:07pm

Perhaps --my=server:7080 could be the problem as well, I don’t see server defined anywhere as a host. Again, not too familiar with Kubernetes so I might be totally off the mark here.

@pawan is the resident Kubernetes expert, so might be able to help when he comes online later today.

MichelDiz · December 11, 2017, 11:23pm

It’s a just normal Docker.

I tried using these configs below to try to “isolate”, but nothing.

    depends_on:
      - serverapi
    links:
      - serverapi

Updated:


command: dgraph server --my=server:7080 --memory_mb=2048 --zero=zero:5080
command: dgraph server --my=server:7081 --memory_mb=1048 --zero=zero:5081

command: dgraph zero --port_offset -2000 --my=zero:5080
command: dgraph zero --port_offset -2001 --my=zero:5081

Can you show the logs that you get? Do you get the same problem when you run the commands outside of Docker?

pawan · December 12, 2017, 12:52am

Hey @MichelDiz

Are you using Docker Compose or Docker Swarm for this?

We have some sample docker_compose files for both here https://docs.dgraph.io/deploy/#cluster-setup-using-docker-swarm. The HA setup starts 6 Dgraph Server and 3 Zero nodes. You could modify it to your use case.

To help you with your config I need some information.

Are you trying to setup a cluster with 2 Dgraph Zero and Server nodes?
If this is the case then Zero should have different idx. Pass --idx 1 to first Zero and --idx 2 to second Zero. No need no pass idx to Server as it automatically gets it.
Do you want to run all on same machine or on multiple machines?
What command are you using to bootup this setup?

MichelDiz · December 12, 2017, 1:19am

Docker Compose

PS. Not a cluster

I saw this, but I really wanted to have two different Dgraph instances on the same Host.

MichelDiz · December 12, 2017, 1:56am

the terminal recorded https://youtu.be/N6PHG-QqzjM

obs: Isn’t a cluster.

The below yml I edited, was missing “network” in the services. But it still keeps making errors.

Ok, so from what I understand you want to run two completely unrelated instances of Dgraph (Server and Zero) on the same machine using Docker Compose.

You can do it using the following docker-compose.yml

version: "3"
services:
  zero1:
    image: dgraph/dgraph:latest
    volumes:
      - /tmp/data1:/dgraph
    ports:
      - 6080:6080
    restart: on-failure
    command: dgraph zero --port_offset -2000 --my=zero1:5080
  server1:
    image: dgraph/dgraph:latest
    volumes:
      - /tmp/data1:/dgraph
    ports:
      - 8080:8080
      - 9080:9080
    restart: on-failure
    command: dgraph server --my=server1:7080 --memory_mb=2048 --zero=zero1:5080
  zero2:
    image: dgraph/dgraph:latest
    volumes:
      - /tmp/data2:/dgraph
    ports:
      - 6081:6081
    restart: on-failure
    command: dgraph zero --port_offset -1999 --my=zero2:5081
  server2:
    image: dgraph/dgraph:latest
    volumes:
      - /tmp/data2:/dgraph
    ports:
      - 8081:8081
      - 9081:9081
    restart: on-failure
    command: dgraph server --my=server2:7081 --memory_mb=2048 --zero=zero2:5081 -o 1

You can also verify that things are setup correctly and both of your single server clusters are working fine by checking
