The feature that allows you to revert to a previous version of a container in Kubernetes is automated rollbacks. This is a functionality associated with Kubernetes deployments, which enables you to manage updates to your applications. When you deploy a new version of an application, Kubernetes keeps a history of previous versions. If the new version fails or does not perform as expected, you can quickly revert back to a stable previous version using the rollback feature.

This process is integral to maintaining application reliability and ensuring that any faults introduced by new deployments can be addressed swiftly, minimizing downtime or disruption. Automated rollbacks improve the overall efficiency of managing application lifecycles within Kubernetes by streamlining the return to a known good state without manual intervention.

The other options, while related to container management and infrastructure, do not provide the specific capability to revert to prior versions of deployed applications effectively. Automated rollbacks specifically focus on the deployment process, making it the right choice for managing application versioning in Kubernetes.
