Namespace Node Affinity (1.0.0)

Namespace Node Affinity 1.0.0

Namespace Node Affinity is a Kubernetes mutating webhook which provides the ability to define node affinity for pods on a namespace level. It is a replacement for the PodNodeSelector admission controller and it is useful when using a managed k8s control plane such as GKE or EKS where you do not have the ability to enable additional admission controller plugins and the PodNodeSelector might not be available. The only admission controller plugin required to run the namespace-node-affinity mutating webhook is the MutatingAdmissionWebhook which is already enabled on most managed Kubernetes services such as EKS. It might still be useful on AKS where the PodNodeSelector admission controller is readily available as using namespace-node-affinity allows a litte bit more flexibility than the node selector by allowing you to set node affinity (only requiredDuringSchedulingIgnoredDuringExecution is supported for now) for all pods in the namespace.
