Pod Priority

Kubernetes allows you to associate a priority with a Pod. If there are resource constraints, if a new Pod with high priority is requested to be scheduled, the Kubernetes scheduler may evict the Pods with lower priority in order to make room for the new high-priority Pod.

Consider an example where you are a cluster administrator and you run both critical and non-critical workloads in the cluster. An example is a Kubernetes cluster for a bank. In this case, you would have a payment service as well as the bank's website. You may decide that processing payments are of higher importance than running the website. By configuring Pod priority, you can prevent lower-priority workloads from impacting critical workloads in your cluster, especially in cases where the cluster starts to reach its resource capacity. This technique of evicting lower-priority Pods to schedule more critical Pods could be faster than adding additional nodes and would help you better manage traffic...
