# Kubernetes ReplicationController

A Kubernetes ReplicationController ensures that a specified number of identical pod replicas are running at all times. It monitors existing pods and automatically creates or removes them to maintain the desired count. This helps keep applications available and resilient, even if pods fail or nodes go down.

```
gcp.k8s_replication_controller
```
