I have a deploy host with kolla-ansible, a control node and a compute node. all nodes are on my intranet so they don't have internet access. I have got everything installed and configured on all nodes according to documentation and now I am wondering when I try to build the containers and deploy, does kolla need access to the internet?

I have a local docker registry running but it currently has no images. I have tested it and I am able to push and pull images from it. But won't kolla use internet access for pull all the required images into the registry?

I followed all the openstack documentation but I am just wondering if there are additional changes I need to make since I don't have internet access?
