Nutanix REST API v2 で Protection Domain の Snapshotを作成してみる。

create_pd-snapshot.py

import sys
import json
import requests
import time

args = sys.argv
conf_file = args[1]
pd_name = args[2]

seconds_to_wait_snapshot_report = 5

def main():
    with open(conf_file, "r") as file:
        conf = file.read()
        conf = json.loads(conf)
    prism_addr = conf["prism_address"]
    prism_user = conf["user_name"]
    prism_pass = conf["password"]

    base_url = 'https://' + prism_addr + ':9440/PrismGateway/services/rest/v2.0/'
    insecure_warn = requests.packages.urllib3.exceptions.InsecureRequestWarning
    requests.packages.urllib3.disable_warnings(insecure_warn)
    s = requests.Session()
    s.auth = (prism_user, prism_pass)
    s.headers.update({'Content-Type': 'application/json; charset=utf-8'})

    # Create PD Snapshot.
    url = base_url + 'protection_domains/' + pd_name + '/oob_schedules'
    oob_schedule = s.post(url, data='{}', verify=False).json()
    #print(json.dumps(oob_schedule, indent=2))
    oob_schedule_id = oob_schedule['schedule_id']

    # Show PD Snapshot.
    time.sleep(seconds_to_wait_snapshot_report)
    url = base_url + 'protection_domains/' + pd_name + '/dr_snapshots/?oob_schedule_ids=' + str(oob_schedule_id)
    dr_snapshot = s.get(url, verify=False).json()
    print(json.dumps(dr_snapshot, indent=2))

if __name__ == '__main__':
    main()

準備

• 事前にPD作成＆VM追加しておく。例でのPD名は pd01
• Prismの接続情報を記載したファイル（./prism-config.json）を作成しておく。

実行例

Snapshotの作成完了が情報取得にまに合わない場合は、
スクリプト内の seconds_to_wait_snapshot_report を増やす。

$ python create_pd-snapshot.py ./prism-config.json pd01
