Kubernetes configuration file is world-readable. This is insecure

[alvarolop]

Everytime that we run a helm command we get the following output

helm repo add tl500 https://rht-labs.com/todolist/

WARNING: Kubernetes configuration file is group-readable. This is insecure. Location: /home/developer/.kube/config
WARNING: Kubernetes configuration file is world-readable. This is insecure. Location: /home/developer/.kube/config
"tl500" has been added to your repositories

The command works, but it is disturbing for participants.

The problem is with the folder, not with the file, I'm not applying any change yet because I don't know if it may have some implications for other parts of the code:

ls -la /home/developer/.kube
