Manage Helm applications

The container management module supports interface-based management of Helm, including creating Helm instances using Helm templates, customizing Helm instance parameters, and managing the full lifecycle of Helm instances.

This section will take cert-manager as an example to introduce how to create and manage Helm applications through the container management interface.
