DNS issue install OpenShift on OpenStack



Hi, 


I'm trying to install openshift on openstack and I've been following https://github.com/openshift/openshift-ansible-contrib/tree/master/playbooks/provisioning/openstack I got past the openstack bit and now I'm installing openshift with “ansible-playbook openshift-ansible/playbooks/byo/config.yml” it got pretty far. 


Except it I got this error:

I used the option of letting it install a DNS server in the openstack section, and I used this setting “public_dns_nameservers: [8.8.8.8,8.8.4.4]”, however it seems that it isn't using the dns server it installed, and hence internal DNS doesn't resolve.  


Is there a way to get the openstack-ansible playbooks to use the internal dns (which was created by “ansible-playbook openshift-ansible-contrib/playbooks/provisioning/openstack/provision.yaml”), which in my case is “10.2.100.5”? 


I figure I must have messed something up in the OpenStack provision section. But I don’t know what. 


Thanks,


Joel
