Which version of Helm was used and how does Helm 3 differ from Helm 2?

The project used Helm 3.

Main differences between Helm 3 and Helm 2:

• No Tiller: Helm 2 used a server component called Tiller to manage releases, which ran in the Kubernetes cluster. Helm 3 removed Tiller, improving security and simplifying architecture.

• Enhanced security: Helm 3 uses Kubernetes RBAC directly, allowing better access control.

• CRD support: Improved handling of Custom Resource Definitions, now managed more flexibly.

• Kubernetes compatibility: Helm 3 better supports newer Kubernetes versions and their features.

• New commands and improved CLI: Some commands were changed or enhanced for ease of use.

Example command to install a chart in Helm 3:

helm install my-release my-chart/
