title: Kubernetes kubeadm init fails due to dial tcp 127.0.0.1:10248: connect: connection refused
body: <p>I'm trying to setup a very simple 2 node k8s 1.13.3 cluster in a vSphere private cloud. The VMs are running Ubuntu 18.04. Firewalls are turned off for testing purposes. yet the initialization is failing due to a refused connection. Is there something else that could be causing this other than ports being blocked? I'm new to k8s and am trying to wrap my head around all of this. </p>
  
  <p>I've placed a vsphere.conf in /etc/kubernetes/ as shown in this gist.

  <p>I've also created a config file to point to when I run <code>kubeadm init</code>. Here's the example of it'\s content. 
  <a href="https://gist.github.com/spstratis/086f08a1a4033138a0c42f80aef5ab40" rel="noreferrer">https://gist.github.com/spstratis/086f08a1a4033138a0c42f80aef5ab40</a></p>
  
  <p>When I run 
  <code>sudo kubeadm init --config /etc/kubernetes/kubeadminitmaster.yaml</code>
  it times out with the following error. </p>
  
  <pre><code>[kubelet-check] Initial timeout of 40s passed.
  [kubelet-check] It seems like the kubelet isn't running or healthy.
  [kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get http://localhost:10248/healthz: dial tcp 127.0.0.1:10248: connect: connection refused.
  </code></pre>
  
  <p>Checking <code>sudo systemctl status kubelet</code> shows me that the kubelet is running. I have the firewall on my master VM turned off for now for testing puposes so that I can verify the cluster will bootstrap itself.  </p>

  <p>Here are some additional logs below showing that the connection to <a href="https://192.168.0.12:6443/" rel="noreferrer">https://192.168.0.12:6443/</a> is refused. All of this seems to be causing kubelet to fail and prevent the init process from finishing. </p>
