使用Python对openstack进行运维操作

A：Python是openstack中最常用的编程语言之一，它可以与openstack的API交互，完成各种运维操作。以下是使用Python对openstack进行运维操作的一些示例：

1.创建一个虚拟机

from openstack import connection
conn = connection.Connection(auth_url='http://openstack.example.com:5000/v3',
                             project_name='admin', 
                             username='admin', 
                             password='password',
                             user_domain_name='Default', 
                             project_domain_name='Default')
                            
image = 'Ubuntu 20.04' 
flavor = 'm1.small' 
network = 'private' 
keypair = 'mykeypair' 
name = 'test_vm' 
server = conn.create_server(
    name=name, 
    image=image, 
    flavor=flavor, 
    network=network, 
    key_name=keypair
)

2.列出所有虚拟机

servers = conn.compute.servers()
for server in servers:
    print(server.name)

3.删除一个虚拟机

server_id = 'xxxxxx'
server = conn.compute.find_server(name_or_id=server_id)
conn.compute.delete_server(server)

4.创建一个容器

from openstack import connection
conn = connection.Connection(auth_url='http://openstack.example.com:5000/v3',
                             project_name='admin', 
                             username='admin', 
                             password='password',
                             user_domain_name='Default', 
                             project_domain_name='Default')

image = 'ubuntu:14.04' 
container = 'test_container' 
command = 'echo "Hello World"' 
conn.create_container(
    name=container, 
    image=image, 
    command=command
)

5.列出所有容器

containers = conn.container.list()
for container in containers:
    print(container.name)

6.删除一个容器

container_id = 'xxxxxx'
container = conn.container.get(container_id)
conn.container.delete(container)

以上仅是一些简单的示例，Python的openstack SDK提供了大量的API，能够完成openstack的各种运维操作。
