Error checking push permissions -- make sure you entered the correct tag name, and that you are authenticated correctly; UNAUTHORIZED: authentication;

Question

I am trying to deploy application on K8s using skaffold, kaniko and desktop-docker. Getting below error msg

error checking push permissions -- make sure you entered the correct tag name, and that you are authenticated correctly, and try again: checking push permission for "index.docker.io/chandramgc/autodockerdeployer:6d5351a-dirty": UNAUTHORIZED: authentication required; [map[Action:pull Class: Name:chandramgc/autodockerdeployer Type:repository] map[Action:push Class: Name:chandramgc/autodockerdeployer Type:repository]] pod has failed

Looking of any guidance in resolving the issue. Any help is appreciated.
