How to check if a given version of Kubernetes supports the api version for a pod object?

Question

Kubernetes

Hello everyone,

in the yaml manifest there is a line,

apiVersion: apps/v1beta1
kind: Deployment

is there some command will the api be backwards compatible with the current version of the cube without running the manifest?

kubectl explain deployment | grep -e "VERSION:" produces a completely different version ( extensions/v1beta1 ) , but nevertheless kubectl apply -f manifest.yaml works fine,

all the best,
Vadim

It is best to look at the API Reference
https://kubernetes.io/docs/reference/generated/kub...
https://kubernetes.io/docs/reference/generated/kub...

In the Release Notes, you can see that in 1.18 they left only apps/v1 for Deployment
