如何使用 python 脚本在 GCP 中创建 DNS 记录集

Question

我正在尝试开发一个 Python 自动化脚本，将“A”类型的 DNS 记录集添加到我现有的 GCP DNS 托管区域“my-sites”中

import json
from google.oauth2 import service_account
from google.cloud import dns
from google.cloud.exceptions import NotFound

gcp_dns_credentials={
  "type": "service_account",
  "project_id": "mygcpprojectid-1122",
  "private_key_id": "myprivkeyid",
  "private_key": "-----BEGIN PRIVATE KEY-----\nmyprivatekey\n-----END PRIVATE KEY-----\n",
  "client_email": "client-mail@mygcpprojectid-1122.iam.gserviceaccount.com",
  "client_id": "myclientid",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/client-mail%40mygcpprojectid-1122.iam.gserviceaccount.com"
}

project_id="mygcpprojectid-1122"
zone_name="my-sites"
dns_credentials = service_account.Credentials.from_service_account_info(gcp_dns_credentials)

client = dns.Client(project=project_id,credentials=dns_credentials)
zone = client.zone(zone_name)
create_records=dns.resource_record_set.ResourceRecordSet(name="mydnsrecord2.mygcpproject.com",record_type="A",ttl=300,rrdatas=["13.66.xx.xx"],zone=zone)

此脚本执行既不会抛出错误也不会创建 DNS 记录集。我提到了这个文档 - https://cloud.google.com/python/docs/reference/dns/latest/resource-record-set

谁能帮帮我:)

Answer 1

没有报错，因为在Google Cloud DNS端还没有做任何事情。

DNS 更改是自动进行的，这意味着您可以进行多项更改（添加、删除等）并一次应用所有更改。所有更改生效或 none 执行（回滚）。

DNS 操作是通过更改集执行的。这意味着创建更改列表（例如创建/修改/删除资源记录）。

add_record_set() 方法追加到变更集 link.

create() 方法应用变更集 link。此方法实际上是修改您的 DNS 服务器资源记录。

只是用 python 代码重申@JohnHanley 解决方案

from google.oauth2 import service_account
from googleapiclient import discovery

gcp_dns_credentials={
  "blah blah": "all dummy credentials in json format already mentioned in the question "
}
project_id="mygcpprojectid-1122"
zone_name="my-sites"

credentials = service_account.Credentials.from_service_account_info(gcp_dns_credentials)
service = discovery.build('dns', 'v1', credentials=credentials)

change_body = {
    "additions": [
        {
      "name": "mydnsrecord2.mygcpproject.com.",
      "type": "A",
      "ttl": 300,
      "rrdata": ["13.66.xx.xx"]
      }
  ]
}

request = service.changes().create(project=project_id, managedZone=zone_name, body=change_body)
response = request.execute()

此脚本执行将创建 mydnsrecord2.mygcpproject.com record-set
