+Add `EXTERNAL-IP` for puppet, puppetca services to `/etc/hosts` on the
+external agent you want to register to this stack. IPs can change, so
+check output of `kubectl get services -A -o wide` to get correct IPs.
+
+```
+# /etc/hosts
+10.100.87.56 puppet.default.svc.cluster.local
+10.111.47.194 puppetca.default.svc.cluster.local
+```
 
 You can verify dns is working with:
