Spot config webhook

This chart will install a mutating admission webhook, that annotates pods in a deployment with a specific annotation that works with BanzaiCloud's spot-scheduler. Pods are annotated based on a specific configmap that's updated by Pipeline. The webhook also sets "spot-scheduler" as schedulerName for these pods.

Installing the Chart

$ helm repo add banzaicloud-stable http://kubernetes-charts.banzaicloud.com/branch/master
$ helm repo update

$ helm install --name <name> banzaicloud-stable/spot-config-webhook
