How to know the optional or must required parameters in the kubernetes object manifest file?

Kubernetes
#1

Is there any command or something like that to get to know about the optional and required parameters instead of referring to the documentation ?

HI @dnpuneeth3

Not really. There’s 2 ways

  1. The documentation
  2. kubectl explain
kubectl explain pod.spec.containers

Fields that can come beneath the requested field (pod.spec.containers) are listed, and any that are required are listed as such, e.g.

   name <string> -required-
     Name of the container specified as a DNS_LABEL. Each container in a pod
     must have a unique name (DNS_LABEL). Cannot be updated.

I actually raised a ticket a while ago to ask them to include in the explain output whether a field is mutable, i.e. can be edited on a running container, and to put -mutable- on the description.

For instance, for a pod, there are very few mutable properties. image is one that can be changed.
