Does anyone know the way to do this on a client-go or the API resources that kubectl describe pod us-CodePudding

I cannot find the appropriate method to do this.

Does anyone know the way to do this on a client-go or the API resources that kubectl describe pod uses?

CodePudding user response：

you can see it on the code of the kubectl describe command

Here is an example code of getting pod with client-go:

/*
A demonstration of get pod using client-go
Based on client-go examples: https://github.com/kubernetes/client-go/tree/master/examples
To demonstrate, run this file with `go run <filename> --help` to see usage

package main
