PythonからのAPI
以下に、Apstra APIを使用したPython 3のコード例を示します。
APIユーザーログイン
import requests, sys
# IP of Cloudlabs AOS Server
aos_server = '172.16.90.3'
username = 'admin'
password = 'aos aos'
# authenticate and get a auth token
url = 'https://' + aos_server + '/api/user/login'
headers = { 'Content-Type':"application/json", 'Cache-Control':"no-cache" }
data = '{ \"username\":\"' + username + '\", \"password\":\"' + password + '\" }'
response = requests.request("POST", url, data=data, headers=headers, verify=False)
print('POST',url,response.status_code)
if response.status_code != 201:
sys.exit('error: authentication failed')
auth_token = response.json()['token']
print(auth_token)
headers = { 'AuthToken':auth_token, 'Content-Type':"application/json", 'Cache-Control':"no-cache" }
API - 設計図
# get blueprint ID ... assuming there is only one
url = 'https://' + aos_server + '/api/blueprints'
response = requests.request('GET', url, headers=headers, verify=False)
print('GET', url, response.status_code)

blueprint_name = response.json()['items'][0]['label']
print(blueprint_name, blueprint_id)
API - 設計図ラック
# get a list of racks
bound_to = ''
url = 'https://' + aos_server + '/api/blueprints/' + blueprint_id + '/racks'
response = requests.request('GET', url, headers=headers, verify=False)
print('GET', url, response.status_code)
for item in response.json()['items']:
bound_to += '{\"system_id\":\"' + item['leafs'][0]['id'] + '\"},'
bound_to = bound_to[:-1]
print(bound_to)
API - ブループリントルーティングゾーン(セキュリティゾーン)
# get routing zone ID ... assuming there is only one
url = 'https://' + aos_server + '/api/blueprints/' + blueprint_id + '/security-zones'
response = requests.request('GET', url, headers=headers, verify=False)
print('GET', url, response.status_code)

security_zone_name = response.json()['items'][item]['vrf_name']
security_zone_id = item
break
print(security_zone_name, security_zone_id)
API - 設計図仮想ネットワーク
# create a virtual network
vn_name = "My-VN"
url = 'https://' + aos_server + '/api/blueprints/' + blueprint_id + '/virtual-networks'
data = '{\"label\":\"' + vn_name + '\",\"vn_type\":\"vxlan\",\"bound_to\":[' + bound_to + '],\"security_zone_id\":\"' + security_zone_id + '\"}'
print(data)
