编写Python程序 要求使用openstack api 开发

在一个搭建有openstack的服务器上使用openstack提供的zun环境，在服务器节点的/root目录下，编写Python程序create_zun.py文件，对接 openstack api，要求上传CentOS7_1804.tar容器，命名为centos7.5-docker，创建并启动zun-container容器（如果存在同名容器，代码中需先进行删除操作）。输出容器名和id和详细信息。
请问一下这个应该如何搭建
同时 有一个示范程序 但是放到机器上运行出现报错

//导入库
from keystoneauth1.identity import v3
from keystoneauth1 import session
from keystoneclient.v3 import client as keyclient
#auth_url为keystone的endpoint入口
//def 定义一个函数
def get_keystone_session():
//定义变量auth 存放认证信息
    auth = v3.Password(auth_url="http://192.168.31.68:5000/v3", username="admin", password="000000", project_name="admin", user_domain_id="default", project_domain_id="default")
///定义变量sess 
    sess = session.Session(auth=auth)
    return sess
#定义好keystone的接口
def get_keystone_client():
//获取get_keystone_session 返回值 认证信息
    sess = get_keystone_session()
    keystone = keyclient.Client(session=sess)
    return keystone
keystone = get_keystone_client()
#查询keystone项目列表[2,4,5,6,7,8]
list = keystone.projects.list()
for p in list:
    print(p)
