通过 openstack api 的方式操作 flavor

获取flavor列表

import json, requests

url = "http://172.16.1.151:5000/v3/auth/tokens"
body = {
  "auth": {
    "identity": {
      "methods": [
        "password"
      ],
      "password": {
        "user": {
          "domain": {
            "name": "demo"
          },
          "name": "admin",
          "password": "000000"
        }
      }
    },
    "scope": {
      "project": {
        "domain": {
          "name": "demo"
        },
        "name": "admin"
      }
    }
  }
}

headers = {
    "Content-Type": "application/json",
}

token = requests.post(url, data=json.dumps(body), headers=headers).headers['X-Subject-Token']

flavors = requests.get('http://controller:8774/v2.1/flavors', headers={'X-Auth-Token': token})
json_flavors = json.loads(flavors.text)
for i in json_flavors['flavors']:
    print(i)

创建新的flavor

# 创建云主机类型
