Why is it that almost every time I do the:
kubectl get pod <podname> -o yaml > filename.yaml command I get a bunch of random managed feilds?

This is the full definition of an object, with all default fields that exist in k8s, these are often not used or used for more thorough pods definitions. You can reduce output adding:
-o yaml | grep -v {}

Mohamed Ayman:
Also, it is recommend to use yaml file to create ur object instead of the kubectl.

@Ethan Benedict kubectl v1.21 does not have managedfields enabled by default, but can be added using --show-managed-fields
