3.x to 4.x

Starting from version 4.0.0, the node exporter chart is using the Kubernetes recommended labels. Therefore you have to delete the daemonset before you upgrade.

kubectl delete daemonset -l app=prometheus-node-exporter
helm upgrade -i prometheus-node-exporter prometheus-community/prometheus-node-exporter

If you use your own custom ServiceMonitor or PodMonitor, please ensure to upgrade their selector fields accordingly to the new labels.

From 2.x to 3.x

Change the following:

hostRootFsMount: true

to:

hostRootFsMount:
  enabled: true
  mountPropagation: HostToContainer
