ADR-MB-008: Helm chart standard

Status​

Accepted

Context​

To improve maintainability, consistency, and scalability of our Helmfile-based infrastructure, we want to standardize the Helm charts used across our projects. Currently, charts may be created ad-hoc using helm create or by copying various example templates, leading to inconsistencies and increased maintenance overhead.

Decision​

We will adopt the Bitnami Helm chart template as the standard for creating new Helm charts within our infrastructure. The Bitnami template offers several advantages, including:

  • Best practices for chart structure and configuration
  • Features such as automatic detection of OpenShift environments
  • Built-in support for resource presets and other common patterns
  • Strong community support and regular updates

All new product integrations and internal charts will be based on the Bitnami template, unless there is a strong justification for an exception.git s

Consequences​

Pros:

  • ✅ Consistent and maintainable Helm charts across the organization
  • ✅ Leverage community best practices and features
  • ✅ Easier onboarding for new team members

Cons:

  • ❌ Slightly more initial effort required to adapt to the Bitnami template structure
  • ❌ May require migration or refactoring of existing charts to align with the new standard
