# While enabled, this will add the scheduler to the default scheduler plugins,
# this will make it affect all pods in the cluster.
addToDefaultScheduler: true
# If addToDefaultScheduler if false, this will be the name of the scheduler,
# and it will only affect pods with: [schedulerName: kube-arch-scheduler].
nonDefaultSchedulerName: kube-arch-scheduler
# The weight of each architecture,
# if a pod can sit on both, it will prefer the one with the higher weight.
# The default weight of undefined architectures is 0, meaning none will have
# any particular preference.

Development
Use this command to run the scheduler locally while connected to your Kubernetes cluster’s context:
go run main.go --authentication-kubeconfig ~/.kube/config --authorization-kubeconfig ~/.kube/config --config=./example/scheduler-config.yaml --v=2
You can use the example deployment in order to test the scheduler on a live pod:
kubectl deploy -f example/busybox.yaml
