<p>I have configured amazon certificate manager, ALB Ingress Controller and a domain names for my application. I can access my application through port 80 and port 443 (all certificates works just fine). However I would like to redirect all coming traffic from HTTP to HTTPS automatically so that people who typed the domain name by itself is redirected to HTTPS. I have followed <a href="https://kubernetes-sigs.github.io/aws-alb-ingress-controller/" rel="noreferrer">this page</a> and <a href="https://kubernetes-sigs.github.io/aws-alb-ingress-controller/guide/ingress/annotation/" rel="noreferrer">this one</a>but I cannot make it work</p>

<p>this is my ingress.yaml file:</p>

<pre><code>apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: metabase
  namespace: bigdata
  annotations:
    kubernetes.io/ingress.class: alb

    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'

</code></pre>

<p>this is my service:</p>

<p>ad this is my deployment:</p>

<p>thanks for your support! :-)</p>

<p>I was able to make it work!! 
basically I modified the ingress.yaml and service.yaml files</p>

<p>ingress.yaml looks like this:</p>

<pre><code>apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: metabase
  namespace: bigdata
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-east-2:***:certificate/****
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": { "Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/group: metabase # name of my app

  labels:
    app: metabase

spec:
  rules:
    - http:
        paths:
          - path: /*
            backend:
              serviceName: ssl-redirect
              servicePort: use-annotation
          - path: /*
            backend:
              serviceName: metabase
              servicePort: 443
</code></pre>

<p>and my service looks like this:</p>

<pre><code>apiVersion: v1
kind: Service
metadata:
  name: metabase
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: arn:aws:acm:us-east-2:***:certificate/***
  namespace: bigdata
  labels:
    app: metabase
spec:
  ports:
    - name: https
      protocol: TCP
      port: 443
      targetPort: http-server
    - name: http
      protocol: TCP
      port: 80
      targetPort: http-server
  selector:
    app: metabase
  type: LoadBalancer
</code></pre>
