Show HN: Noe, a mutating webhook to make multi-arch simpler in Kubernetes

Hi folks!

Our team provides a multi-cluster, multi-region, multi-tenant, Kubernetes cluster as a service to the rest of the company [1].

Recently, we worked on adding ARM-nodes support and we found out that people usually rely on annotations to get the job done. Then, we realized that this is double work. You need to:

1. Build the image for multi-architecture

2. Annotate your deployment with the correct architecture

Isn't there a better way? So, Noe was born. Noe is a Kubernetes mutating webhook that dynamically assigns node architectures to match the requirements of container images within a Pod. It simplifies mixed-architecture deployments (e.g. ARM and x86) by ensuring that Pods are scheduled on nodes capable of executing all their images.

You can see more in the Github project.
