Can you share your code?

It's hard to guess without that, but solely from the error, it sounds like you may have invalid YAML in pod.yaml. E.g., Extra or missing whitespace somewhere.

@brikis98 I just cloned this repo and deleted two files which i do not need, no other changes.

Ah this is a bug in terratest, where it is returning both stdout and stderr and the warnings are leaking in to the output. As a workaround, you can resolve this by addressing the warnings that the command is returning to you:

WARNING: Kubernetes configuration file is group-readable. This is insecure. Location: /home/nikhil/.kube/config
WARNING: Kubernetes configuration file is world-readable. This is insecure. Location: /home/nikhil/.kube/config

@yorinasub17 thanks, updating the .kube/config file permission resolved the issue.

[nik9839]

@yorinasub17 should i close the issue or wait till you PR on terratest is approved ?

[yorinasub17]

Thanks for closing the loop! PR in terratest is released and merged so closed issue.
