Helm installation requirements and included components
Harness recommends Helm package manager for the installation and deployment of Self-Managed Enterprise Edition. Helm offers benefits including:
- Declarative and dynamic application management
- Built-in scalability
- Chart reuse across environments
- Repeatable results you can automate
The Harness Helm chart packages the core modules and components that are required to operate Harness at scale.
