<h1 id="configuring-externaldns-to-use-the-openshift-route-source">Configuring ExternalDNS to use the OpenShift Route Source<a class="headerlink" href="#configuring-externaldns-to-use-the-openshift-route-source" title="Permanent link">&para;</a></h1>
<p>This tutorial describes how to configure ExternalDNS to use the OpenShift Route source.<br />
It is meant to supplement the other provider-specific setup tutorials.</p>
<h3 id="for-ocp-4x">For OCP 4.x<a class="headerlink" href="#for-ocp-4x" title="Permanent link">&para;</a></h3>
<p>In OCP 4.x, if you have multiple <a href="https://docs.openshift.com/container-platform/4.9/networking/ingress-operator.html">OpenShift ingress controllers</a> then you must specify an ingress controller name (also called router name), you can get it from the route&rsquo;s <code>status.ingress[*].routerName</code> field.<br />
If you don&rsquo;t specify a router name when you have multiple ingress controllers in your cluster then the first router from the route&rsquo;s <code>status.ingress</code> will be used. Note that the router must have admitted the route in order to be selected.<br />
Once the router is known, ExternalDNS will use this router&rsquo;s canonical hostname as the target for the CNAME record.</p>
<p>Starting from OCP 4.10 you can use <a href="https://github.com/openshift/external-dns-operator">ExternalDNS Operator</a> to manage ExternalDNS instances. Example of its custom resource for AWS provider:<br />
