StackState Self-hosted v5.0.x
StackState doesn't specify a specific storage class on its PVC's (persistent volume claims) by default, for cloud providers like EKS and AKS this means the default storage class will be used.
The defaults for those storage classes are typically to delete the PV (persistent volume) when the PVC is deleted. Note that even when running
helm deleteto remove a stackstate release the PVC's will remain present within the namespace and will be reused if a
helm installis run in the same namespace with the same release name.
To remove the PVC's either remove them manually with
kubectl delete pvcor delete the entire namespace.
You can customize the
sizesettings for different volumes in the Helm chart. The example values.yaml files provided in the GitHub Helm chart repo show how you can customize the
sizeof volumes. The
storageClasscan be added in a similar fashion.
In the example below, all services that store data are switched to rely on the storageClass named
standardand not use the default storageClass configured for the Kubernetes cluster:
# size of volume for each Elasticsearch pod
# size of volume for HDFS data nodes
# size of volume for HDFS name nodes
# size of persistent volume for each Kafka pod
# size of persistent volume for each Zookeeper pod
