Kaniko produces " UNAUTHORIZED: authentication required" error when building an integration route with Dockerhub

[omarsmak]

If we setup camel-k with docker registry enabled and publish strategy Kaniko, e.g:

kamel install --registry docker.io --organization<user-id> --registry-secret my-docker-hub-pass --force --build-publish-strategy=Kaniko

Building a sample integration using the command kamel run Sample.java --dev , will produce the following error in Kaniko container:

If I use Spectrum publish strategy, everything works fine.

Please note, I am using Azure Kubernetes Cloud (AKS)
