The secure port should not be disabled for the API server
Set up the kubernetes integration.
Do not disable the secure port.
The secure port is used to serve https with authentication and authorization. If you disable it, no https traffic is served and all traffic is served unencrypted.
Run the following command on the master node:
ps -ef | grep kube-apiserver
Verify that the --secure-port argument is either not set or is set to an integer value between 1 and 65535.
Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the master node and either remove the –secure-port parameter or set it to a different (non-zero) desired port.
You need to set the API Server up with the right TLS certificates.
By default, port 6443 is used as the secure port.
