The code automatically detects the proxyUID and proxyGID from RunAsUser/RunAsGroup and exclude them from interception, defaulting to 1337

### 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.

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.

Warning: unlike the `IstioOperator` profiles, these profiles cannot enable or disable certain components.

a set of control plane settings and components. While the entire mesh respects the same APIs and config,
apps may target different 'environments' which contain different instances and variants of Istio.

- Better security: separate Istio components reside in different namespaces, allowing different teams or
roles to manage different parts of Istio. For example, a security team would maintain the

1. Start debugging process and verify it is working. For example, try adding a breakpoint at Reconcile logic and apply a new CR.

### Relationship between the CLI and controller

The CLI and controller share the same API and codebase for generating manifests from the API. You can think of the
controller as the CLI command `istioctl install` running in a loop in a pod in the cluster and using the config

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

## Uninstalling the Chart

To uninstall/delete the chart:

```console
helm delete ztunnel
```

## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/ztunnel
```

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.

## Uninstalling the Chart

To uninstall/delete the `istiod` deployment:

```console
helm delete istiod --namespace istio-system
```

## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/istiod
```

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.

`priorityClassName` can be used. You can install in other namespace only on K8S clusters that allow
'system-node-critical' outside of kube-system.

## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/istio-cni
```

### Profiles

* Utilizes Gateway injection, simplifying upgrades, allowing gateways to run in any namespace, and avoiding repeating config for sidecars and gateways.
* Published to official Istio Helm repository.
* Single chart for all gateways (Ingress, Egress, East West).

#### General concerns

For a smooth migration, the resource names and `Deployment.spec.selector` labels must match.

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.

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.
