This is my micro letter, there is a problem you can add the exchange
and to the introduction of Kolla not elaborate too much here, there are many online documents. This article is for the latest version of Kolla, can not solve a single-node deployment ceph-osd problem (found in the multi-node test can not be deployed Ceph-osd). In the latest version of kolla, the official website has been given notice to the shelf Ceph, the specific information in the following figure: 
This piece of article will not solve the problem by modifying the deployment ceph kolla-ansible source.
The deployment process is as follows:
1. Preparations
1.1 Installation Centos7.5 system here. I use virtualbox create a virtual machine, you can use two cards. The first for the management network, you can access the Internet, use the second network as an example, start without the need to configure IP.

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

[root@openstack ~]# pip install kolla-ansible --ignore-installed PyYAML5.3 安装kolla
[root@openstack ~]# pip install kolla6. 配置kolla-ansible
6.1 创建kolla目录，复制globals.yml，passwords.yml
[root@openstack ~]# mkdir -p /etc/kolla/
[root@openstack ~]# cp /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/6.2 由于此环境在虚拟机部署，所以virt_type的类型设置为qemu
[root@openstack ~]# mkdir -p /etc/kolla/config/nova/
[root@openstack ~]# vim /etc/kolla/config/nova/nova-compute.conf
[libvirt]
virt_type = qemu
cpu_mode = none6.3 配置ceph.conf，设备ceph副本数，此环境为一台节点，3个OSD盘，设置副本为1即可，如果是三台节点，9OSD盘，副本为3。
[root@openstack ~]# vim /etc/kolla/config/ceph.conf

osd pool default size = 1
osd pool default min size = 16.4 配置globals.yml

注：如果此环境所在的网络中还有其它使用Kolla部署的openstack，那么需要修改globals.yml中的
