两种方案：

方案一：下载已经打包好镜像，解压缩后，加载docker registry容器

方案二：通过kolla的dockerfile，在线编译生成镜像，再加载到docker registry容器中

方案一：

# wget https://tarballs.openstack.org/kolla/images/centos-source-registry-pike.tar.gz
# mkdir /data/registry
# tar xzf centos-source-registry-pike.tar.gz -C /data/registry
# docker run -d -p 4000:5000 --restart=always -v /data/registry/:/var/lib/registry --name registry registry

Install kolla-ansible.

# pip install kolla-ansible
# cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/kolla/
# cp /usr/share/kolla-ansible/ansible/inventory/* .

方案二：

build images on the controller node and push images to the docker private registry.
