16 Update environment variables on a pod template.
17 List environment variable definitions in one or more pods, pod tem‐
20 plates. Add, update, or remove container environment variable defini‐

22 deployment configurations). View or modify the environment variable
23 definitions on all containers in the specified pods or pod templates,
24 or just those that match a wildcard.
25 If "--env -" is passed, environment variables can be read from STDIN
28 using the standard env syntax.
