Generators in kubectl are deprecated

[James Harmison]

Kubernetes has deprectated generators in kubectl run in version 1.18.

https://kubernetes.io/docs/setup/release/notes/#deprecation-4

Remove all the generators from kubectl run. It will now only create pods. Additionally, deprecates all the flags that are not relevant anymore.

This affects the sections:

• Intro

  • kubectl run nginx --image=nginx --replicas=3

• Validation and generators

  • To construct the HTTP request, kubectl uses something called generators which is an abstraction that takes care of serialization.

• API groups and version negotiation

  • After kubectl generates the runtime object

• etcd

  • (kinda like the inverse process of kubectl's generators)

And that's all I could find with some grokking.
