urllib3.exceptions.MaxRetryError: HTTPSConnectionPool

[jincheng-xiaosu]

My k8s cluster is installed quickly on the cloud server through kubeadm. I want to access my cluster through the public network address through the SDK of Python. The following error is reported：

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='203.195.203.45', port=6443): Max retries exceeded with url: /api/v1/pods (Caused by SSLError(SSLCertVerificationError("hostname '203.195.203.45' doesn't match either of 'k8s-master', 'kubernetes', 'kubernetes.default', 'kubernetes.default.svc', 'kubernetes.default.svc.cluster.local', '10.1.0.1', '172.16.32.7'")))

The issue might be with your certs.

1. kubeadm alpha certs renew all
2. how to renew the certificate when apiserver cert expired? kubernetes/kubeadm#581

[jincheng-xiaosu]

My cluster is just built and deployed with kubeadm tool. The certificate is self signed. I changed self.verify_ssl under configuration.py to false

c = client.Configuration()

c.verify_ssl = False

client.Configuration.set_default(c)

@jincheng-xiaosu -- the common names mentioned in the self-signed certificate don't match the server that you are pinging. I am guessing there are proxies/load balancers in between.

You can disable hostname matching by setting configuration.assert_hostname = False along with configuration.verify_ssl = False.

This should make it working with kubeadm clusters being proxied over.
