What is the purpose and main features of Helm in the Kubernetes ecosystem?

Helm is a package manager for Kubernetes that simplifies deploying and managing applications in a cluster.

Key features of Helm:

• Templates: Allow creating parameterized Kubernetes manifests, making reuse and customization easier.
• Charts: Helm packages are called charts — a set of files describing Kubernetes resources for an application.
• Version management: Helm allows managing application versions and rolling back to previous versions.
• Dependency management: Charts can depend on other charts, simplifying complex deployments.

Example usage:

helm install myapp ./mychart

This will deploy the application described in the chart with the name "myapp" in Kubernetes.
