This is a helm chart author who also wants to make their chart available as a bundle for people to try out. For example, the author of the MySQL or MongoDB charts.
They only run their bundle locally, or on a single cloud environment, just to make sure that it works.
They only run their bundle on their own cloud, it’s not super configurable or portable.
They need to be able to work with the bundle in their local development environment, and then hand it off to another person to deploy it in the test and production environments.
They need to configure and deploy the same bundle into different environments which run on different platforms and use different underlying service providers. For example, their test environment uses an on-premise Kubernetes cluster and a mega shared MS SQL server, while their production environment uses AKS and Azure SQL Server.
