[Pods](/docs/user-guide/pods) in Kubernetes 1.8 and later can have priority. Priority
indicates the importance of a Pod relative to other Pods. When a Pod cannot be scheduled,
the scheduler tries to preempt (evict) lower priority Pods to make scheduling of the
pending Pod possible. In Kubernetes 1.9 and later, Priority also affects scheduling
order of Pods and out-of-resource eviction ordering on the Node.
[Pods](/docs/user-guide/pods) can have _priority_. Priority indicates the
importance of a Pod relative to other Pods. When a Pod cannot be scheduled,
the scheduler tries to preempt (evict) lower priority Pods so that the pending
Pod can be scheduled. In Kubernetes 1.9 and later, Priority also affects
scheduling order of Pods and out-of-resource eviction ordering on the Node.

Pod priority and preemption are moved to beta since Kubernetes 1.11 and are enabled by default in
this release and later.

Please note that these features were not enabled by default in Kubernetes 1.10 or older.
If you want to use these features in those versions, please follow the instructions given in
documents of those versions on how to enable the feature.

**Note**: Pod priority and preemption are enabled by default in Kubernetes 1.11
and higher. To use these features in Kubernetes 1.8 through 1.10, follow the
instructions in the documentation for your Kubernetes version.
