title: Using kubeconfig contexts simply
body: <p>I need to use now multiple cluster, currently what I did is simple put all the kubeconfig
  under <code>.kube</code> folder and any time update the config file with the cluster which I need , e.g.</p>
  <p><code>mv config cluserone</code>
  <code>vi config</code>
  insert new kubeconfig to the <code>config</code> file and start working with the new cluster,
  Let say inside the <code>/Users/i033346/.kube</code> I've all the kubeconfig file one by one.</p>
  <p>is there a way to use them as contexts without creating a new file which contain all of them.</p>
  <p>I try to use also <a href="https://github.com/ahmetb/kubectx" rel="nofollow noreferrer">kubectx</a> however when I use:</p>
  <pre><code>export KUBECONFIG=/Users/i033346/.kube/trial
  </code></pre>
  <p>and</p>
  <pre><code>export KUBECONFIG=/Users/i033346/.kube/prod
  </code></pre>
  <p>and use <code>kubectx</code> I always get the last one and doenst get list of the defined contexts,any idea?</p>
