An application that monitors the availability of Kubernetes storage in end-to-end manner.
pie verifies that PVs are successfully provisioned on the specified nodes for the specified storage classes and that the PVs can be successfully accessed. It outputs the results as metrics.
- Kubernetes: 1.29, 1.28, 1.27
-
Create values.yaml. At least the following setting is mandatory.
controller: monitoringStorageClasses: [<storage_classes_to_be_monitored>]
-
Then you can install it using Helm.
helm repo add pie https://topolvm.github.io/pie helm install pie --values values.yaml
