Unable to build a binary or compile the example files

[sanjiths]

I am trying to build a binary for https://github.com/vladimirvivien/k8s-client-examples/blob/master/go/podlist/maing.go
I have imported the required packages and facing the below issue:

[sansampa@localhost podlist]$ go build maing.go 
import cycle not allowed
package main
	imports k8s.io/apimachinery/pkg/apis/meta/v1
	imports k8s.io/apimachinery/pkg/labels
	imports k8s.io/apimachinery/pkg/util/validation
	imports net
	imports internal/nettrace
	imports net/http/httptrace
	imports crypto/tls
	imports crypto/tls
import cycle not allowed
package main
	imports k8s.io/apimachinery/pkg/apis/meta/v1
	imports k8s.io/apimachinery/pkg/labels
	imports k8s.io/apimachinery/pkg/util/validation
	imports net
	imports internal/nettrace
	imports net/http/httptrace
	imports internal/nettrace
/usr/local/go/src/net/dnsclient.go:12:8: non-standard import "golang.org/x/net/dns/dnsmessage" in standard package "net"
/usr/local/go/src/net/http/h2_bundle.go:47:9: non-standard import "golang.org/x/net/http/httpguts" in standard package "net/http"

Could you pls tell me how to proceed?

@sanjiths I updated the Go example with support for Go modules. Take a look to see if that helps.

Hi @vladimirvivien! It really helped :) thank you so much (y)
Now, I have one more problem! How can i use this binary from inside a container or a pod?

I am facing below issue:

./podlist tree
2021/01/26 10:42:39 stat /home/vault/.kube/config: no such file or directory
[vault@vaultagent-0 tmp]$ vi /home/vault/.kube/config:

Thanks,
Sanjith S

@sanjiths the code in this example is written to be used outside of a cluster.
But it's easy to change your code to make it work from within a cluster.
Checkout the link below (from the client-go project), it shows what to change to fix your issue:
