Windows Node Support

Kubecost can run on clusters with mixed Linux and Windows nodes. The Kubecost pods must run on a Linux node.
Deployment
When using a Helm install, this can be done simply with:
helm install kubecost \
--repo https://kubecost.github.io/cost-analyzer/ cost-analyzer \
--namespace kubecost --create-namespace \
-f https://raw.githubusercontent.com/kubecost/cost-analyzer-helm-chart/develop/cost-analyzer/values-windows-node-affinity.yaml
Detail
The cluster must have at least 1 Linux node for the Kubecost pods to run on:
Use a nodeSelector for all Kubecost deployments:
spec:
  nodeSelector:
    kubernetes.io/os: linux
  containers:
For DaemonSets, set the affinity to only allow scheduling on Windows nodes:
  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: kubernetes.io/os
            operator: In
            values:
            - linux
See the list of all deployments and DaemonSets here.
Metrics
Collecting data about Windows nodes is supported by Kubecost as of v1.93.0.
Accurate node and pod data exists by default, since they come from the Kubernetes API.
Kubecost requires cAdvisor for pod utilization data to determine costs at the container level.
Currently, for pods on Windows nodes: pods will be billed based on request size.
