Anchore policy validator

This chart deploys an admission-server that is used as a ValidatingWebhook in a k8s cluster. If it's working, kubernetes will send requests to the admission server when a Pod creation is initiated. The server checks the image, which is defined in PodSpec, against configured Anchore-engine API. If the API responds with an error, that the image is not valid according to defined policy, k8s will reject the Pod creation request.

Installing the Chart

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