For the last few weeks, I’ve been working with the OpenShift Kube Descheduler and OpenShift Kube Descheduler Operator.
I posted some test-cases for the seven Descheduler Profiles to demonstrate how the Profiles operate under specific conditions. Note these are unsupported test cases.
The following examples are:
I hope this helps you adopt the OpenShift Kube Descheduler Operator.
- Evicting pods using the descheduler
- Kubernetes: Pod Topology Spread Constraints Use topology spread constraints to control how Pods are spread across your cluster among failure-domains such as regions, zones, nodes, and other user-defined topology domains. This can help to achieve high availability as well as efficient resource utilization.
- Kubernetes: Inter-pod affinity and anti-affinity Inter-pod affinity and anti-affinity allow you to constrain which nodes your Pods can be scheduled on based on the labels of Pods already running on that node, instead of the node labels.
- Kubernetes: Well-Known labels and taints
- Adding Labels to a Running Pod
- Label Selector for k8s.io
- Pod Affinity and AntiAffinity Examples
- Scheduling pods using a scheduler profile
