```

_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._

## Installing the Chart

Before installing, ensure CRDs are installed in the cluster (from the `istio/base` chart).

For consistency, the same profiles are used across each chart, even if they do not impact a given chart.

Explicitly set values have highest priority, then profile settings, then chart defaults.

As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
When configuring the chart, you should not include this.

## Uninstalling the Chart

However, we can workaround this by placing all of (1) under a specific key (.Values.defaults).
We can then merge the profile onto the defaults, then the user settings onto that.
Finally, we can set all of that under .Values so the chart behaves without awareness.

1) `base` chart creates cluster-wide CRDs, cluster bindings and cluster resources. It is possible to change the namespace from `istio-system` but it is not recommended.

```console
helm install istio-base -n istio-system manifests/charts/base --set profile=openshift
```
