A workload resource that manages a replicated application, ensuring that
a specific number of instances of a {{< glossary_tooltip text="Pod" term_id="pod" >}} are running.

Will automatically add or remove running instances of a pod, based on a set value for that pod. Allows the pod to return to the defined number of instances if pods are deleted or if too many are started by mistake.
The control plane ensures that the defined number of Pods are running, even if some
Pods fail, if you delete Pods manually, or if too many are started by mistake.
{{< note >}}
ReplicationController is deprecated. See
{{< glossary_tooltip text="Deployment" term_id="deployment" >}}, which is similar.
