我正在尝试连接到我的microk8s Kubernetes集群，它正在使用Python Kubernetes client监听端口16443：#!/usr/bin/python3

import kubernetes

from kubernetes import client

from kubernetes.client import ApiClient

def setup_cluster():

configuration = kubernetes.client.configuration.Configuration()

configuration.host = "https://localhost:16443"

#configuration.cert_file = "ca.crt"

#configuration.key_file = "ca.key"

configuration.api_key["authorization"] = "[the token which I got from kubectl -n kube-system describe secret default-token-abc123]"

api_client = ApiClient(configuration=configuration)

v1 = client.CoreV1Api(api_client=api_client)

print("Listing pods with their IPs:")

ret = v1.list_pod_for_all_namespaces(watch=False)

for i in ret.items:

print("%s\t%s\t%s" % (i.status.pod_ip, i.metadata.namespace, i.metadata.name))

if __name__ == "__main__":

setup_cluster()

如果我没有设置示例中配置的cert_file、key_file或{}中的任何字段，则连接失败的原因是

^{pr2}$

如果我指定api_key，如上面的代码所示，我得到File "/home/richter/examples/kubernetes-python/kubernetes-python-port-ignored/venv/lib/python3.7/site-packages/urllib3/util/retry.py", line 399, in increment

raise MaxRetryError(_pool, url, error or ResponseError(cause))

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='localhost', port=16443): Max retries exceeded with url: /api/v1/pods?watch=False (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)')))

我尝试设置一些证书，如ca.crt和ca.key，如图所示，但是由于File "/home/richter/examples/kubernetes-python/kubernetes-python-port-ignored/venv/lib/python3.7/site-packages/urllib3/util/retry.py", line 399, in increment

raise MaxRetryError(_pool, url, error or ResponseError(cause))

我在Ubuntu19.04上使用microk8s1.15.0(695)和python3.7和kubernetespython客户端10.0.0。在
