Verifying component health always fails with non-default --apiserver-port

[moduspwnens]

System: macOS 10.14.4
minikube version: 1.0.0
Command: minikube start --apiserver-port=6443

When I do this, it always fails in the "Verifying component health" stage. However, kubectl works as expected and the cluster seems to be in good health.

I'm not super familiar with golang, but it appears that the function being called to verify the apiserver's health is here:

minikube/cmd/minikube/cmd/start.go

Line 561 in 58a7045

st, err := bs.GetAPIServerStatus(net.ParseIP(ip))

It's calling a "GetAPIServerStatus" method and passing in only the IP address of the apiserver. The function itself is here:

minikube/pkg/minikube/bootstrapper/kubeadm/kubeadm.go

Line 126 in 89ab0be

url := fmt.Sprintf("https://%s:%d/healthz", ip, util.APIServerPort)

And for the port to use, it looks like it may be referencing a constant declared here as 8443:

minikube/pkg/util/constants.go

Line 27 in 8ba53c6

APIServerPort = 8443

Presumably it should only reference the constant if the user didn't specify the API server port. Although again, my experience with golang is small.

Sorry to hear about this, but good catch! We'll definitely want to add --apiserver-port to our integration tests to make sure this doesn't break again in the future.

Help wanted!
