Kolla是Openstack的子项目，Kolla分为：用kolla来构造镜像、用Kolla-ansible自动化部署OpenStack

1.需要创建一个docker的私有仓库

2.安装kolla

3.构造镜像并把构建好的镜像推到docker私有仓库

4.安装docker篇请看：https://blog.csdn.net/qq_41709494/article/details/94603041

5.安装python3篇请看：https://blog.csdn.net/qq_41709494/article/details/89738929

一、设置docker私有仓库的IP

#以下是开启 Docker 的开机就执行的私有仓库172.25.0.10:4000
# vi /usr/lib/systemd/system/docker.service

改：14 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock 

为：ExecStart=/usr/bin/dockerd --insecure-registry=172.25.0.10:4000

#以下是配置后要重新启动服务
# systemctl  daemon-reload
# systemctl  restart docker

# docker info					#查看docker信息

二、构造docker私有仓库

# mkdir -p /var/lib/registry     #创建空目录映射容器的目录

#以下是创建（仓库）registry:2（标签）容器，并且后台运行，映射端口和映射文件
# docker run -d \
    --name registry \
    -p 4000:5000 \
    -v /var/lib/registry:/var/lib/registry \
registry:2

#以下是请求查看信息
# curl -XGET http://172.25.0.10:4000/v2/_catalog
{"repositories":["v2"]}

三、安装kolla，用kolla-build来构造docker的镜像

# pip3 install -U pip				#升级pip3

#克隆kolla源包
# git clone  https://opendev.org/openstack/kolla.git -b stable/pike

#以下是安装kolla依赖包
# pip3 install -U -r /root/kolla/requirements.txt



#以下是安装kolla依赖包
# pip3 install -r  /root/kolla/test-requirements.txt  -r  /root/kolla/test-requirements.txt

#以下是python3编译的半自动化安装
# python3 setup.py install
#显示如下内容，表示编译成功
Installing kolla-build script to /usr/local/python3/bin

#创建kolla-build的软连接
ln -s /usr/local/python3/bin/kolla-build    /usr/bin/kolla-build

四、生成kolla-build.conf的配置文件，这个文件是高级自定义文件，用来构建镜像的一定要生成文件，否则kolla-build构建不了镜像

# pip3 install -U tox

#以下是创建tox的软连接
# ln -s /usr/local/python3/bin/tox /usr/bin/tox

#以下是切换到/root/kolla的目录下
# cd ~/kolla/

#以下是生成构建配置的kolla-build.conf
# tox -e genconfig

#以下内容是显示成功
________________________________________________________________ summary _________________________________________________________________
  genconfig: commands succeeded
  congratulations :)

#以下是复制kolla-build.conf到/etc/kolla的配置目录，方便管理
# cp /root/kolla/etc/kolla/kolla-build.conf  /etc/kolla/

五、设置阿里云镜像CentOS的Base.repo源和Epel.repo源

# mkdir  /etc/yum.repos.d/bak						#创建bak空目录，存放CentOS-*.repo的官方源

# mv /etc/yum.repos.d/CentOS-* bak/     #移动所有CentOS-开头的文件到bak目录下

#以下是阿里云镜像Base，下载Centos-7.repo到/etc/yum.repos.d的目录下
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

#以下是阿里云镜像Epel，下载Epel.repo到/etc/yum.repos.d的目录下
# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

# yum clean all				#清除数据缓存

# yum makecache				#生成数据缓存

六、构造镜像推送到私有仓库的172.25.0.10:4000里面

kolla-build --registry 172.25.0.10:4000  --push
