The `values.yaml` API is intended to maintain a *minimal core set of configuration* that most users will use.
For bespoke use cases, [Helm Chart Customization](https://istio.io/latest/docs/setup/additional-setup/customize-installation-helm/#advanced-helm-chart-customization) can be used
to allow arbitrary customizations.

# Helm Profiles

This folder provides a variety of "profiles" for helm installation.
While a user can just explicitly pass this with `--values/-f`.

However, Istio also provides a feature to bundle these with the charts, which is convenient when installing from remote charts.
For details, see `copy-templates` Makefile target, and `manifests/zzz_profile.yaml`.

Any changes to this folder should have a `make copy-templates` applied afterwards.
