How do you understand the term deployment in the context of Kubernetes and what is it used for?

In Kubernetes, a Deployment is an object that manages the creation and updating of a set of Pods. It provides a declarative description of the desired state of the application, such as how many replicas of Pods should be running, and automatically maintains this state.

Main tasks of Deployment:

• Automatic launching of the required number of Pods.
• Updating the application without downtime (rolling update).
• Rollback to a previous version in case of errors.

Using Deployment allows easy scaling of the application and managing its versions without manual intervention.
