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.

### Overview

- [istio-cni Helm chart](../manifests/charts/istio-cni/templates)
    - `install-cni` daemonset - main function is to install and help the node CNI, but it is also a proper server and interacts with K8S, watching Pods for recovery.

# Istio Ztunnel Helm Chart

This chart installs an Istio ztunnel.

## Setup Repo Info

```console
helm repo add istio https://istio-release.storage.googleapis.com/charts
helm repo update
```

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

## Installing the Chart

To install the chart:

```console
helm install ztunnel istio/ztunnel
```

## Uninstalling the Chart

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
```

	warning=$$(cat manifests/helm-profiles/warning-edit.txt | sed ':a;N;$$!ba;s/\n/\\n/g') ; \
	for chart in $(CHARTS) ; do \
		for profile in manifests/helm-profiles/*.yaml ; do \
			sed "1s|^|$${warning}\n\n|" $$profile > manifests/charts/$$chart/files/profile-$$(basename $$profile) ; \
		done; \
		cp manifests/zzz_profile.yaml manifests/charts/$$chart/templates ; \
	done

# Istiod Helm Chart

This chart installs an Istiod deployment.

## Setup Repo Info

```console
helm repo add istio https://istio-release.storage.googleapis.com/charts
helm repo update
```

_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.
