<p>I don't even know if this is possible, but would it be wise?  I don't know, but I think that the master node would not have to handle as much as the worker nodes.  With that assumption I wanted to make my master as energy efficient as possible by moving it to my RPiV4 (has 4GB ram).</p>

<p>The building of a hybrid architecture cluster required some improvements from the main Kubernetes distribution provided since version 1.12. Kubernetes had AMD64 and ARM64 images for a while but to be able to transparently create the hybrid cluster, it required that Docker Manifests were pushed to the repositories where the main image tag pointed to the tagged architecture images.
I really recommend you to to look for those articles: </p>
