Why
Having a single source for Helm chart makes it easier to test and deploy the product and reduces the complexity of installing backend/frontend/utility applications separately.
Description
A "Product Helm Chart" is a released helm chart that contains all the components of a product ready to deploy. This can either be achieved by creating a single Helm chart for the product or by combining the Helm charts of the different components into a single chart using dependencies.
Product Helm Chart rules
- name of the Chart should be just the
product-namewithout prefix or suffix (similar to the leading product repository) - values file should contain all available variables (even from subcharts) with default values and comments about what they do
- helm install command should successfully install the chart to any supported Kubernetes version cluster (without overwriting default values)
- helm test runs without errors (see TRG 5.09 - Helm test)
- create a single helm chart for the whole product or combine charts into a single one using dependencies feature
