Kubernetes HTTPS Ingress in Google Container Engine

Question

I want to expose a HTTP service running in Google Container Engine over HTTPS only load balancer.

How to define in ingress object that I want HTTPS only load balancer instead of default HTTP?

Or is there a way to permanently drop HTTP protocol from created load balancer? When I add HTTPS protocol and then drop HTTP protocol, HTTP is recreated after few minutes by the platform.

Ingress:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: myapp-ingress
spec:
  backend:
    serviceName: myapp-service
    servicePort: 8080

Answer 1

In order to have HTTPs service exposed only, you can block traffic on port 80 as mentioned on this link:

You can block traffic on :80 through an annotation. You might want to do this if all your clients are only going to hit the loadbalancer through https and you don't want to waste the extra GCE forwarding rule, eg:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test
  annotations:
    kubernetes.io/ingress.allow-http: "false"
spec:
  tls:
  # This assumes tls-secret exists.
  # To generate it run the make in this directory.
  - secretName: tls-secret
  backend:
    serviceName: echoheaders-https
    servicePort: 80
