# Priority Classes The AWX and Postgres pods can be assigned a custom PriorityClass to rank their importance compared to other pods in your cluster, which determines which pods get evicted first if resources are running low. First, [create your PriorityClass](https://kubernetes.io/docs/concepts/scheduling-eviction/pod-priority-preemption/#priorityclass) if needed. Then set the name of your priority class to the control plane and postgres pods as shown below. ```yaml spec: ... control_plane_priority_class: awx-demo-high-priority postgres_priority_class: awx-demo-medium-priority ```
