kubectl run with stdin not working in k8s.RunKubectl method

Open developer-guy opened this issue 4 years ago • 3 comments

This is my code below : output2, _ := k8s.RunKubectlAndGetOutputE(t, kubectlOptions, "run", "netshoot", "--generator=run-pod/v1", "--image=nicolaka/netshoot", "-i", "--", podCommand)

And the output of that command here is : command.go:87: Running command kubectl with args [run netshoot --generator=run-pod/v1 --image=nicolaka/netshoot -i -- curl http://172.17.0.5:8200/v1]

but after that nothing happens and process stucks here.

I believe you also need the -t flag, but in general I believe interactive commands don't quite work when going through terratest because of the way the logging infrastructure works.

I added -t flag also, but nothing changed @yorinasub17

Running command kubectl with args [run netshoot --generator=run-pod/v1 -it --image=nicolaka/netshoot curl http://172.17.0.5:8200/v1]

Hi, not sure if the issue is still actual, I tested this code, and got results from curl execution:

	curlOutput, _ := k8s.RunKubectlAndGetOutputE(t, options, "run", "netshoot", "--image=nicolaka/netshoot", "-i", "--", "curl", "google.com")
	fmt.Printf("\n%s\n", curlOutput)

Output:
