I am trying to get Kibana 6.2.4 in my GKE Kubernetes cluster running under www.mydomain.com/kibana without success. Though, I can run it perfectly fine with kubectl proxy
and the default SERVER_BASEPATH
.
Here is my Kibana deployment with the SERVER_BASEPATH
removed.

My nginx ingress definition (nginx-ingress-controller:0.19.0):

This results in this nginx location

However, going to /kibana
results in a 404.
Stackdriver

statusCode: 404,

}
I feel as though I am missing some sort of setting with either SERVER_BASEPATH
and/or my nginx ingress configuration.
