ZeroMQ Guide

This guide provides information about how to enable zmq in the CCP.

To use zmq as an rpc backend the following steps are required:

1. fuel-ccp-zmq repository should be added to the repositories list:

repositories:
  repos:
    - git_url: https://git.openstack.org/openstack/fuel-ccp-zmq
      name: fuel-ccp-zmq

2. zmq-proxy and redis images should be built:

ccp build -c zmq-proxy redis

3. rpc service should be configured to use zmq:

services:
  rpc:
    service_def: zmq-proxy

4. rpc and redis services should be added to topology. Example of such topology provided in fuel-ccp/etc/topology-with-zmq-example.yaml
5. configs should be extended with the following values:

configs:
  messaging:
    backend:
      rpc: zmq

Pretty much the same steps required to enable zmq as a notifications backend:

services:
  notifications:
    service_def: zmq-proxy

configs:
  messaging:
    backend:
      notifications: zmq
