Update environment variables on a pod template.
List environment variable definitions in one or more pods, pod templates. Add, update, or remove container environment variable definitions in one or more pod templates (within replication controllers or deployment configurations). View or modify the environment variable definitions on all containers in the specified pods or pod templates, or just those that match a wildcard.
If "--env -" is passed, environment variables can be read from STDIN using the standard env syntax.
Possible resources include (case insensitive):
pod (po), replicationcontroller (rc), deployment (deploy), daemonset (ds), statefulset (sts), cronjob (cj), replicaset (rs)

3 - kubectl set resources
Synopsis
Specify compute resource requirements (CPU, memory) for any resource that defines a pod template. If a pod is successfully scheduled, it is guaranteed the amount of resource requested, but may burst up to its specified limits.
For each compute resource, if a limit is specified and a request is omitted, the request will default to the limit.
Possible resources include (case insensitive): Use "kubectl api-resources" for a complete list of supported resources..

4 - kubectl set selector
Synopsis
Set the selector on a resource. Note that the new selector will overwrite the old selector if the resource had one prior to the invocation of 'set selector'.
A selector must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used. Note: currently selectors can only be set on Service objects.
