Definition

A Kubee Helmet Chart:

is a Chart
- that installs only one application
- with the name of the app installed (ie grafana, not grafana operator)
- that depends on:
  - the kubee Cluster Library Chart to share cluster and installation wide
    - values.yaml file
    - and library
  - and optionally:
    - cross dependency Charts:
      - to bring cross values to create cross conditional expression. Example:
        
        conditional: if cert_manager.enabled then create_certificate_request
        
        cross: if prometheus.enabled then create_grafana_data_source with promtheus.name
      - with a mandatory false condition kubee_internal.dont_install_dependency: false
    - direct/wrapped dependency Chart (for instance, kubee-external-secrets wraps the external-secret Chart)
- with optional:
  - Jsonnet
  - or kustomize
installs only one application as kubee is a platform.
- For instance, installing an application such as grafana can be done via:
  - a raw deployment manifest
  - or the grafana operator
- Only one chart is going to supports this 2 methods.

Each values.yaml file should contain at least the following properties:

The values file should contain different nodes for:

the chart itself
the external services (new relic, grafana cloud, …) - making clear what the parameters are for.

a app charts - a chart that installs an application
a CRD charts - a chart that installs CRDS
a Cluster Chart - a chart that drives the installation of kubernetes distribution
a library chart - a chart that shares values and function
