What is Helm in Kubernetes?

Helm is a package manager specifically designed for Kubernetes applications, which makes it easier to manage complex applications within the Kubernetes environment. It provides a streamlined way to define, install, upgrade, and manage Kubernetes applications by utilizing a packaging format known as charts. A chart contains all the necessary resources and configurations required to deploy an application or service in Kubernetes.

Using Helm, developers can manage application versions and dependencies efficiently, enabling them to easily roll back to previous versions if needed. This simplifies the deployment and maintenance processes, making it particularly valuable in dynamic environments where applications might require frequent changes or updates. Additionally, Helm can facilitate the sharing of applications and configurations within a team or across the broader Kubernetes community.

Other options refer to different functionalities not associated with Helm. For instance, while visualizing cluster performance is important, it is not something Helm does. Similarly, managing network policies pertains to configuring security measures for communication between pods, which is outside Helm's scope. Lastly, securing container images relates to image scanning and vulnerability management, also not a function of Helm. Thus, option B accurately describes Helm's role within the Kubernetes ecosystem.
