K8s cluster in peered VPC can't reach RDS cluster
For my Peering Connection, I went to:
&quot;Actions&quot; -&gt; &quot;Edit DNS Settings&quot; -&gt; &quot;Allow accepter VPC (vpc-&lt;id&gt;) to resolve DNS of requester VPC (vpc-&lt;id-default&gt;) hosts to private IP&quot;
and checked it. (It was unchecked before). I had to wait a little while before this took effect.
