Overview
Workload resources exist to create and manage Pods, which should not usually be created directly. Various workload resources implement different pod utilization patterns.
The pod-managing resources described here are some times referred to as higher-level pod controllers or "templated controllers". These controllers are part of and supervised by the controller manager.

Workload Resource
Describe the relationship between pod, deployment, ReplicaSet and workload resources. Which one are controllers and which are not?
Controller
TODO: https://kubernetes.io/docs/concepts/workloads/pods/#pods-and-controllers
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
