title: Can't mount to nfs pod in Kubernetes
body: <p>Community. I need help with my config for the NFS pod in Kubernetes. I can't connect to the NFS pod. Can't understand, what a problem. Need help. I tried connecting with the command:</p>
  <pre class="lang-sh prettyprint-override"><code>mount --options port=2052 --types nfs 10.110.183.188:/upload /upload
  </code></pre>
  <p>and get a <em><code>Connection timeout</code></em> error on my computer. When I try connecting with this command from another pod to NFS I got</p>
  <pre class="lang-sh prettyprint-override"><code>mount: /upload: cannot mount 10.110.183.188:/upload read-only.
  </code></pre>
  <p>kubectl describe to NFS pod write this:</p>
  <pre class="lang-sh prettyprint-override"><code>Serving /exports
  Serving /
  rpcinfo: can't contact rpcbind: : RPC: Unable to receive; errno = Connection refused
  Starting rpcbind
  exportfs: / does not support NFS export
  NFS started
  </code></pre>
  <p>This is my config for NFS pod</p>
