title: cert-manager letsencrypt issuing invalid certs
body: <p>I followed <a href="https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-with-cert-manager-on-digitalocean-kubernetes" rel="nofollow noreferrer">this tutorial</a> to serve a basic application using the NGINX Ingrss Controller, and cert-manager with letsencrypt.</p>
  <p>I am able to visit the website, but the SSL certificate is broken, saying <code>Issued By: (STAGING) Artificial Apricot R3</code>.</p>
  <p>This is my <code>ClusterIssuer</code>:</p>
  <pre><code>apiVersion: cert-manager.io/v1alpha2
  kind: ClusterIssuer
  metadata:
    name: letsencrypt-issuer
    namespace: cert-manager
  spec:
    acme:
      server: https://acme-staging-v02.api.letsencrypt.org/directory
      email: my-email@example.com
      privateKeySecretRef:
        name: letsencrypt-issuer
      solvers:
        - http01:
            ingress:
              class:  nginx
  </code></pre>
  <p>And the <code>Ingress</code>:</p>
  <pre><code>apiVersion: networking.k8s.io/v1
  kind: Ingress
  metadata:
    name: my-app-ingress-dev
    namespace: my-app
    annotations:
      cert-manager.io/cluster-issuer: letsencrypt-issuer
  spec:
    tls:
      - secretName: echo-tls
        hosts:
          - my-app.example.com
    rules:
      - host: my-app.example.com
        http:
          paths:
            - path: /
              pathType: Prefix
              backend:
                service:
                  name: my-app-dev
                  port:
                    number: 80
  </code></pre>
