Example Usage

Based on the number of Pods & Nodes in a cluster, the resource usage differs. Below some values we identified by testing with the clusterloader tool.


As each user cluster contains an etcd StatefulSet with 3 pods, it requires 3 5GB volumes. 5GB might be for some scenarios too big, therefore the size can be configured cluster-wide via the values.yaml.
