Hi Team,
Does anyone know if we export yamls in CKAD exam , do we get metadata.managedFields as well ? if yes how can we get the neat and clean k8’s object yamls exported , please advise

Mohamed Ayman:
Yes, you will need to use imperative commands and export YAML to save time in the exam. These additional fields in the new version of kubernetes.

#3

Mohamed Ayman:
You can only exclude using grep command to decrease the file:
kubectl get pod nginx -o yaml | grep -v "f:" > pod.yaml

#4

Basavraj Nilkanthe:
@Mohamed Ayman I dont see much difference between this approach and i have get YAML file without using grep -v “f:” and with using grep -v “f:”

HITESH RATHOD:
Thanks for the response @Mohamed Ayman ill try to use as much as possible imperative commands but in some cases we may need to export yaml and this addtional metadata makes yaml too long
