By default, traffic for the OpenShift API server is served over
HTTPS with authentication and authorization, and the secure API endpoint
is bound to 0.0.0.0:8443. To ensure that the insecure port configuration
has not been enabled, the insecure-port parameter should be set to 0.
Edit the openshift-kube-apiserver configmap and change the
insecure-port value to 0:
"apiServerArguments":{
...
"insecure-port":[
"1234"
],
...
