Thanks @vrkshetty for this issue.

What does kaniko-secret or docker-config config map look like?

Basically, Kaniko expects a file in /kaniko/.docker/config.json as

{
	"auths": {
		"https://index.docker.io/v1/": {
			"auth": "xxxxxxxxxxxxxxx"
		}
	}
}

Can you try these steps and let us know.

1. create a config.json as mentioned here
2. Create a config map

kubectl create configmap docker-config --from-file=config.json

3. Run kubectl describe configmaps docker-config should give you the contents of config.json
   4 finally volume mount the configmap docker-config at /kaniko/.docker like you have done.

Let me know if that fixes your issue.
