### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.
For example, the `demo` profile offers a preset configuration to try out Istio in a test environment, with additional features enabled and lowered resource requirements.

                && (profile.getDependencyManagement() == null
                        || profile.getDependencyManagement().getDependencies().isEmpty())
                && profile.getDistributionManagement() == null
                && profile.getModules().isEmpty()
                && profile.getSubprojects().isEmpty()
                && profile.getProperties().isEmpty()
