Overview

Workload resources exist to create and manage Pods, which should not usually be created directly. Various workload resources implement different pod utilization patterns.

A workload resource has an associated controller. The controller handles replication, rollout and automatic healing in case of pod failure. For example if a node fails, a controller notices that the pods on that node have stopped working and creates replacement pods, which are scheduled on healthy nodes.

Workload resources:

  • Deployment
  • StatefulSet
  • DaemonSet
  • Jobs
  • CronJob
