How to setup docker-vernemq on Docker Swarm about docker-vernemq

[ioolkos]

Hey @mitchellvanrijkom totally sorry, missed your issue here somehow. My apologies.
Let's see. What would native Docker Swarm support mean? is there anything specific we'd need to enable or script?

Hey @ioolkos No problem! Thanks for the reply.
Docker Swarm is a clustering and orchestration tool for running Docker containers in Services.
https://docs.docker.com/engine/swarm/
To make use of scaling applications and enable load-balancing in the swarm we use Docker Services. This is one level up in the hierarchy of a distributed application of docker. See, https://docs.docker.com/get-started/part3/.

What we would like is when we have deployed VerneMQ broker as a Service. We want to make use of the scaling functionality in docker swarm to scale the numbers of running containers to autojoin a VerneMQ cluster by a simple command instead of defining own containers with the docker run command. See Docker documentation about scaling a service: https://docs.docker.com/engine/swarm/swarm-tutorial/scale-service/. When you want to use Autojoining you are required to set a IP-address of the first VerneMQ container. In a Docker swarm we can make use of Service discovery. Swarm manager nodes assign each service in the swarm a unique DNS name and load balances running containers. You can query every container running in the swarm through a DNS server embedded in the swarm. Thereby no need to set an IP-address.

Let me know if i am unclear in my explanation.

Thanks in advance!

@mitchellvanrijkom I guess this issue might be solved as part of our work in https://github.com/vernemq/vmq-discovery cc: @ioolkos, @codeadict

Yes, that will be possible with vmq-discovery indeed.

Any update for this? I've looked at vmq-discovery but the repo is so bare.

Not yet, vmq-discovery is being worked slowly, work starting new year, contributions always welcome :)

@codeadict sadly I don't know Erlang yet. Thanks anyway, keep up the good work!
