<p>After deleting kubernetes cluster with &quot;terraform destroy&quot; I can't create it again anymore.</p>
<p>&quot;terraform apply&quot; returns the following error message:</p>

</code></pre>
<p>P.S. There seems to be the issue with terraform kubernetes provider for 0.14.7</p>
<p>I couldn't use &quot;load_config_file&quot; = false in this version, so I had to comment it, which seems to be the reason of this issue.</p>
<p>P.P.S. It could also be the issue with outdated cluster_ca_certificate, which terraform tries to use: deleting this certificate could be enough, although I'm not sure, where it is stored.</p>

<p>Before doing something radical like manipulating the state directly, try setting the KUBE_CONFIG_PATH variable:</p>
<pre><code>export KUBE_CONFIG_PATH=/path/to/.kube/config
</code></pre>
<p>After this rerun the <code>plan</code> or <code>apply</code> command.
This has fixed the issue for me.</p>
