Link to the issue (please include a link to the specific documentation or example):
Most of the resources https://github.com/kubernetes-client, https://github.com/kubernetes-client/python/tree/master/examples are lacking one of the most needed examples: how to perform a kubectl apply -f file.yaml

Description of the issue (please include outputs or screenshots if possible):
Currently it seems the API has examples for how to create and delete resources, and most of its examples are around connectivity. An example on the apply -f should be given, especially since these closed tickets should have not been closed at all as no solution was given:
