title: Portworx to ETCD connection doesn't work (http vs https)
body: <p>Done according to <a href="https://kubernetes.io/docs/tasks/administer-cluster/setup-ha-etcd-with-kubeadm/" rel="nofollow noreferrer">this article</a>.</p>
  
  <p>I installed Kubernetes. Then installed etcd cluster that works via HTTPS and listens to the localhost interface only (reachable from inside any Docker container). 
  Now I need persistent volume to install DB cluster. Chose Portworx. It generated daemonset YAML-config. Here is the description of installed daemonset:</p>
  
  <pre><code># kubectl describe daemonset portworx --namespace=kube-system

  <p>But in the log of portworx I see that it is trying to connect to etcd via plain HTTP and obviously get error because cannot interpreter the response wrapped to SSL:</p>
  
  <pre><code># kubectl logs -f pod/portworx-67w7m --namespace=kube-system
  
  &lt;some logs are erased du to lack of relevance&gt;
