PriorityClass

Jan 1, 0001

Definition

PriorityClass is a Kubernetes resource used to define the importance of a pod relative to other pods. It assigns a priority value to pods, which the scheduler uses to make decisions about pod preemption and scheduling order. Higher priority pods can preempt lower priority ones, ensuring critical workloads are scheduled first, especially in resource-constrained environments.

Secure Settings Example

apiVersion: scheduling.k8s.io/v1
kind: PriorityClass
metadata:
  name: high-priority
value: 1000
globalDefault: false
description: "This priority class is for critical system pods."

Insecure Settings Example

apiVersion: scheduling.k8s.io/v1
kind: PriorityClass
metadata:
  name: default-priority
value: 1000
globalDefault: true
description: "This priority class is set as the default for all pods."
