<p>I've tried the following to get HTTP to redirect to HTTPS. I'm not sure where I'm going wrong.</p>

<p><code>ingress-nginx</code> object:</p>

<pre><code>apiVersion: v1
kind: Service
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-type: nlb
    service.beta.kubernetes.io/aws-load-balancer-backend-protocol: http
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:...
    service.beta.kubernetes.io/aws-load-balancer-ssl-ports: https
spec:
  type: LoadBalancer
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
  ports:
    - name: http
      port: 80
      targetPort: http
    - name: https
      port: 443
      targetPort: http
</code></pre>

<p><code>my-ingress</code> object:</p>

<pre><code>apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  namespace: my-namespace
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/secure-backends: "true"
spec:
  tls:
   - hosts:
     - app.example.com
  rules:
  - host: app.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: my-service
          servicePort: 80
</code></pre>

<p>I get a <code>308 Permanent Redirect</code> on HTTP and HTTPS. I guess this makes sense as the NLB is performing the SSL termination and therefore forwarding HTTP to the Nginx service? I guess I would need to move the SSL termination from the NLB to the Nginx service?</p>

<p>Thanks</p>

<p>I believe you do need to move the SSL termination to the ingress controller because I am having the same issue and I appear to be in a permanent redirect situation. The traffic comes into the NLB on 443 and is terminated and sends to the backend instances over port 80. The ingress sees the traffic on port 80 and redirects to https:// and thus begins the infinite loop. </p>
