Bug: Node-local-dns broken #1425

Open bernardhalas opened 1 week ago

bernardhalas commented 1 week ago

Current Behaviour

Deploying dnsutils and running dig www.google.com takes too long (20 ms), which indicates that node-local-dns is broken. After deploying node-local-dns manually, I get resolution time down to 1-2 ms.

Expected Behaviour

node-local-dns is not used, whereas it should be.

Steps To Reproduce

  1. deploy dnsutils
  2. execute dig www.google.com
  3. observe resolution speed

By following the setup guide, I was able to fix the deployment.

@JKBGIT1 found a likely solution, inspired from https://www.alibabacloud.com/help/en/ack/ack-managed-and-ack-dedicated/user-guide/configure-nodelocal-dnscache
