For security vulnerabilities, please don't report a bug (which is public) and instead follow

    * Risk should be assessed in the PR.
        * Have installs and upgrades affected by this feature?
        * Is the feature still being worked on?
        * Is the default behavior altered?
        * Is this turned on by default?
        * How many users are affected by this change?

## Feature implementation

# 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.
