openstack Rocky版本 api獲取例項

方法一：

import sys
from openstack import connection
from openstack import utils

conn = connection.Connection(
    auth_url='http://192.168.10.10/identity',
    username='admin',
    project_name='demo',
    project_domain_name='Default',
    user_domain_name='Default',
    password='admin')

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

for flavor in conn.compute.flavors():
    print(flavor)

data=conn.compute.servers.get(vm)

方法二：

from novaclient import client as nvclient
from keystoneauth1 import loading
from keystoneauth1 import session
loader = loading.get_plugin_loader('password')
auth = loader.load_from_options(auth_url='http://192.168.10.10/identity',
                                username='admin',
                                password='admin',
                                project_name='demo',
                                project_domain_name='Default',
                                user_domain_name='Default')
sess = session.Session(auth=auth)
nova = nvclient.Client(2.1, session=sess)
vm=nova.servers.get(vmid)
