Pods
ReplicaSets
ReplicaControllers
Deployments
StatefulSets
DaemonSets
Jobs
CronJobs

This list shows the standard or default resources that are allowed on every Kubernetes installation, but we can create custom resources to implement any non-standard or more specific application behavior. In this section, we are going to learn about these standard resources so that we can decide which one will fit our application’s needs.

The following applies to all the containers running inside a Pod by default:
