<p><strong>Given:</strong>
I want to run a web application with letsencrypt certs via cert manager</p>

<p><strong>Problem</strong>
I can access the site with http but https doesnt work even I can see that cert-manager created a certificate which is also saved as a secret.</p>

<p><strong>What I did</strong></p>

<p>1.) I installed cert-manager with helm</p>

<pre><code>helm install --name cert-manager --namespace kube-system stable/cert-manager rbac.create=false
</code></pre>

<p>then i applied my k8s yaml.</p>

<pre><code>apiVersion: certmanager.k8s.io/v1alpha1
kind: ClusterIssuer
metadata:
  name: letsencrypt-staging
spec:
  acme:
    server: https://acme-staging-v02.api.letsencrypt.org/directory

    http01: {}

</code></pre>

<p>What am I missing to get also an https route?</p>

<p>I spot a typo in tls: - hosts: - mydomain.comt </p>
