some useful kubectl customisations

nodes.py

# run like this:
# kubectl get nodes -o json | python nodes.py

import json
import sys


format = "%-45s %-12s %6s"
print format % ("NAME", "IP", "IMAGES")

for item in json.load(sys.stdin)["items"]:
    print format % (item["metadata"]["name"],
                    item["status"]["addresses"][0]["address"],
                    sum([len(x["names"]) for x in item["status"]["images"]]))

this could probably be done with jq...
