Roshan Ranasinghe:
thanks @Apaar Sharma … why those are coming in that way?

#4

Apaar Sharma:
these are the managed fields, they are suppressed in the output in the newer versions.

These additional fields in the new version of Kubernetes.
You can only exclude some of these fields using grep command to decrease the file:

kubectl get pod nginx -o yaml | grep -v “f:” > pod.yaml
