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.
