The feature of Kubernetes that allows users to control the transition from the current state of a container to a desired state is automated rollouts and rollbacks. This functionality enables Kubernetes to manage updates to applications in a controlled manner, ensuring that users can specify the desired state of their applications, and Kubernetes will automatically work to transition to that state.

With automated rollouts, Kubernetes incrementally updates containers, which minimizes downtime and reduces the risk of failure. If an issue arises during the update, the rollback capability allows the system to revert to a previous stable version seamlessly. This dynamic adjustment between states ensures that the system maintains operational integrity while adapting to changes.

While self-healing refers to Kubernetes' ability to automatically replace or restart containers that fail or become unresponsive, and manual scaling allows users to explicitly adjust the number of running instances, these features do not provide the same level of control over gradual state transition as automated rollouts and rollbacks do. Replication primarily focuses on maintaining the desired number of container instances running, rather than the process of transitioning between states.
