How can I `kubectl explain` the entire structure of a custom resource?

February 2, 2023

I have a CR in the cluster. I know that there is a filed specialField somewhere in this CRD. I do not know where it is. Right now I am randomly exploring the CRD using kubectl explain path.to.some.filed to try to fiend the filed. Is there some way to explain the entire nested structure using kubectl explain?

What I am looking for is something like this

kubectl explain-magic my-crd

my-crd
 a
  b
   c
 other
  field 
 more
  fields
 very 
  nested
   field

or as an alternative

my-crd
a
a.b
a.b.c
other
other.field
more
more.fields
very
very.nested
very.nested.field

>Solution :

Add the –recursive flag to display all of the fields at once without descriptions. Information about each field is
retrieved from the server in OpenAPI format.

from kubectl help explain.

Just do: kubectl explain --recursive my-crd
