<p>This tutorial describes how to setup ExternalDNS for usage within a Kubernetes cluster using Civo DNS Manager.</p>
<p>Make sure to use <strong>&gt;0.12.2</strong> version of ExternalDNS for this tutorial.</p>
<h2 id="managing-dns-with-civo">Managing DNS with Civo<a class="headerlink" href="#managing-dns-with-civo" title="Permanent link">&para;</a></h2>
<p>If you want to learn about how to use Civo DNS Manager read the following tutorials:</p>
<p><a href="https://www.civo.com/learn/configure-dns">An Introduction to Managing DNS</a></p>
<h2 id="get-civo-token">Get Civo Token<a class="headerlink" href="#get-civo-token" title="Permanent link">&para;</a></h2>
<p>Copy the token in the settings fo your account</p>
<p>The environment variable <code>CIVO_TOKEN</code> will be needed to run ExternalDNS with Civo.</p>
<h2 id="deploy-externaldns">Deploy ExternalDNS<a class="headerlink" href="#deploy-externaldns" title="Permanent link">&para;</a></h2>
<p>Connect your <code>kubectl</code> client to the cluster you want to test ExternalDNS with.<br />
Then apply one of the following manifests file to deploy ExternalDNS.</p>

<p>Note the annotation on the service; use the same hostname as the Civo DNS zone created above.</p>
<p>ExternalDNS uses this annotation to determine what services should be registered with DNS. Removing the annotation will cause ExternalDNS to remove the corresponding DNS records.</p>
<p>Create the deployment and service:</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-3-1" name="__codelineno-3-1" href="#__codelineno-3-1"></a><span class="gp">$ </span>kubectl<span class="w"> </span>create<span class="w"> </span>-f<span class="w"> </span>nginx.yaml
</code></pre></div>
<p>Depending where you run your service it can take a little while for your cloud provider to create an external IP for the service.</p>
<p>Once the service has an external IP assigned, ExternalDNS will notice the new service IP address and synchronize the Civo DNS records.</p>
<h2 id="verifying-civo-dns-records">Verifying Civo DNS records<a class="headerlink" href="#verifying-civo-dns-records" title="Permanent link">&para;</a></h2>
<p>Check your <a href="https://www.civo.com/account/dns">Civo UI</a> to view the records for your Civo DNS zone.</p>
<p>Click on the zone for the one created above if a different domain was used.</p>
<p>This should show the external IP address of the service as the A record for your domain.</p>
<h2 id="cleanup">Cleanup<a class="headerlink" href="#cleanup" title="Permanent link">&para;</a></h2>
<p>Now that we have verified that ExternalDNS will automatically manage Civo DNS records, we can delete the tutorial&rsquo;s example:</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-4-1" name="__codelineno-4-1" href="#__codelineno-4-1"></a>$ kubectl delete service -f nginx.yaml
<a id="__codelineno-4-2" name="__codelineno-4-2" href="#__codelineno-4-2"></a>$ kubectl delete service -f externaldns.yaml
