DEPRECATED This repository has moved

With upcoming deprecation of helm/charts repository, the Node Problem Detector Helm Chart has moved to Delivery Hero’s Helm Repository: https://github.com/deliveryhero/helm-charts

You can use this new Helm repository by doing:

helm install --name <RELEASE_NAME> deliveryhero/node-problem-detector
# Upgrade existing installation
helm upgrade --name <RELEASE_NAME> deliveryhero/node-problem-detector
