Default installation with manifests

To obtain a default installation without Prometheus alerting interlock or Slack notifications:

latest=$(curl -s | jq -r '.[0].tag_name')
kubectl apply -f "$latest/kured-$latest-dockerhub.yaml"

If you want to customise the installation, download the manifest and edit it in accordance with the following section before application.

Using the Helm-Chart

Kured also provides its own helm-chart. Detailed instructions and documentation can be found here.
