Lab 8.3 Delete works with --all-namespaces

jdnovick

There is a mistake in the lab. The lab says

1. Try to delete all Pods with the app=nginx label, in all namespaces. You should receive an error as this function must be
   narrowed to a particular namespace. Then delete using the appropriate namespace.
   student@lfs458-node-1a0a:~$ kubectl delete pods -l app=nginx \
--all-namespaces
Error: unknown flag: --all-namespaces
   

but it works for me. This is a mistake in the lab. Maybe this functionality didn't exist previously but it works now. kubectl delete --help shows --all-namespaces as an option.

Hi @jdnovick,

Thanks for bringing this to our attention. You are correct, this behavior has recently changed.
The lab exercise will be corrected in a future course update release.
