Question

Kubernetes LoadBalncer http->https redirection does not work

Hi there!

I’m setting up Nginx ingress controller on my Kubernetes Cluster, and I can’t make http->https redirect to work.

apiVersion: v1
kind: Service
metadata:
  name: nginx-ingress-controller
  labels:
    component: "controller"
  annotations:
    service.beta.kubernetes.io/do-loadbalancer-protocol: "https"
    service.beta.kubernetes.io/do-loadbalancer-certificate-id: "d6312b2d-c313-4b03-9030-ccc40f1afed5"
    service.beta.kubernetes.io/do-loadbalancer-tls-passthrough: "false"
    service.beta.kubernetes.io/do-loadbalancer-redirect-http-to-https: "true"
spec:
  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: http
    - name: https
      port: 443
      protocol: TCP
      targetPort: http
  selector:
    app: nginx-ingress
    component: "controller"
  type: "LoadBalancer"

As you can see in nginx ingress controller Service definition, I’m using correct annotation, however, when I visit http://mydomain.com, I get ERR_CONNECTION_REFUSED, instead of getting redirection to https.

When I use https://mydomain.com, it works as expected, i.e. response from ingress resource is rendered.

Did I configure nginx ingress correctly? What am I missing? Thank you.

I had the same issue, using the same YAML as you. I solved it by adding the following annotation

service.beta.kubernetes.io/do-loadbalancer-protocol: “http”

This sets the correct forwarding rules protocol in the load balancer and the http to https now works
