python-3.x - Kubernetes Python 客户端连接问题

Question

我已经设置了官方 Kubernetes Python 客户端 ( https://github.com/kubernetes-client/python )。

我正在运行 Python 代码以连接到 Kubernetes 集群，但它抛出了 错误 :

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='****', port=6443): Max retries exceeded with url: /api/v1/namespaces/default/pods (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 110] Connection timed out',))

安装要求:

kubectl使用相同的配置工作正常 $HOME/.kube/config和相同的代理设置。

下面是我的代码:

from kubernetes import client, config
config.load_kube_config()
v1 = client.CoreV1Api()
print("Listing pods with their IPs:")
ret = v1.list_pod_for_all_namespaces(watch=False)

Answer 1

就我而言，只需通过 load_kube_config 加载配置即可也没有用。我最终首先运行了一个代理:

kubectl proxy --port=8888

然后使用 Configuration 更改主机目的:

configuration = client.Configuration()
configuration.host = "localhost:8888"
api_client = client.CoreV1Api(client.ApiClient(configuration))
