q - when i run below command, i get lots of extra cluster information.? I think the --export works in my local but not in the lab. Believe thats depricated already, What could be an alternative?

kubectl get pods <pod_name> -o yaml

kubectl get pods <pod_name> --export -o yaml

this command errors out as --export is not recognised as valid param

Yes Anurag - it has been deprecated in 1.18 and removed in 1.19 - see this PR : https://github.com/kubernetes/kubernetes/pull/88649

You will have to do (as you have already hinted in your post)

kubectl get pods <pod_name> -o yaml

And remove metadata.managedFields and status fields from YAML and use it for future reuse .

From exam perceptive sometime you can getaway by not removing above two fields - for example if they ask you to add resource request/limit to existing pod - you can export yaml add/update/modify needed additional fields . Then just do kubectl replace --force --grace-period=0 -f <manifest.yaml> that should just do it . This is just to save time during exam . In real life cleanup above mention two fields just keep your files tidy .
