Configure this tutorial
Set the example values for your environment; related explanations and copy panels update together. Never enter passwords, private keys or tokens. Values stay in this tab and are not sent to the server or share links. Check actual DNS, certificates and network policy before running commands.
Different IP addresses, domains or ports? Open the settings below, change the values and select “Apply to tutorial”, then copy the updated commands.

Finish with a bounded evidence record
Keep the source Pod UID, resolver configuration, exact query/status, DNS/Service endpoint observations, policy finding and final application response. This guide is documented, not a claim of executed cluster tests. Debug containers and temporary query logging, if separately approved, must be removed through their owning lifecycle after review; never erase the incident evidence or delete cluster DNS resources.
