Comment 2 for bug 1808165

The logs show that the zun-compute process cannot connect to docker daemon, possibly due to a configuration issue. A few things to check:

* Which version of kolla-ansible you are using (want to make sure you have this patch: https://review.openstack.org/#/c/565240/).
* Add the following to your globals.yaml and see if there is any luck:

  docker_custom_option: " -H unix:///var/run/docker.sock -H tcp://<your_ip_address>:2375"
