问题描述
我正在我的计算机上的 multipass 上运行 Kubeflow 部署。我已经根据 this tutorial 部署了 Kubeflow。我正在创建可重复使用的组件 according to the documentation，这是我的管道中一个组件的步骤的一部分。
db_name = os.getenv("MysqL_DB_NAME")
user_name = os.getenv("MysqL_USER_NAME")
password = os.getenv("MysqL_PASSWORD")
endpoint = os.getenv("MysqL_ENDPOINT")
with open('query.sql','r') as file:
query = file.read()
con = MysqL.connector.connect(
user=user_name,password=password,host=endpoint,database=db_name,use_pure=True
)
用户名、密码等数据由 Kubernetes 密钥提供。我已经测试了凭据和连接性，并且能够使用 MysqL 工作台连接到数据库，但是当从我的管道组件运行它时，我收到以下错误：
Traceback (most recent call last):
File "/usr/local/lib/python3.9/site-packages/MysqL/connector/network.py",line 482,in open_connection
addrinfos = socket.getaddrinfo(self.server_host,File "/usr/local/lib/python3.9/socket.py",line 953,in getaddrinfo
for res in _socket.getaddrinfo(host,port,family,type,proto,flags):
socket.gaierror: [Errno -3] Temporary failure in name resolution
During handling of the above exception,another exception occurred:

raise errors.InterfaceError(
MysqL.connector.errors.InterfaceError: 2003: Can't connect to MysqL server on 'DATABASE URL HERE' (-3 Temporary failure in name resolution)
在我看来，这可能是网络配置问题，但我不知道是什么问题。关于可能导致此问题的原因有什么想法吗？
