Zevrant
<p>Based on the <code>dig</code> output you shared <code>zevrant-oauth2-service-db</code> is resolving to <code>92.242.140.2</code> but it looks like the IP address of your K8s service is <code>10.97.75.171</code> (ClusterIP) (based on the output you shared too).</p>
<p>If you hit <code>10.97.75.171 5432</code> you should be able to access your Postgres database, provided that you don't have any Kubernetes Network Policy and/or firewall blocking access. Make sure you that in your Postgres config you are binding the server to <code>0.0.0.0</code> otherwise if it's something like <code>localhost</code> you will only be able to get to it from the pod.</p>
<p>So the question is what is <code>92.242.140.2</code>? Wny is coredns responding to a query to <code>zevrant-oauth2-service-db</code> with <code>92.242.140.2</code>? Is there a DNS forwarder configured in coredns? Is there a default domain configured that is not part of <code>svc.cluster.local</code>?</p>
