A KRM function to enable Helm on Kustomize with Glob support
The motivation for this project is quite simple. While Helm integration in Kustomize is already available, it falls short in scenarios where dynamic use of Glob is required to fetch all necessary values.yaml files. In such cases, it lacks support. With the likelihood of glob support being added to Kustomize remaining uncertain for the foreseeable future, this project was initiated to address this limitation.
