Noe: Kubernetes Mutating Webhook for Node Architecture Selection

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.

Features

• Automatically adjusts node affinities based on container images' supported architectures
• Improves deployment efficiency by removing the need for manual node selector configuration
• Facilitates seamless mixed-architecture deployments by ensuring compatibility between ARM and x86 nodes

Running Tests

Run all tests using the following command:

go test ./...
