- [istio/istio](README.md). This is the main code repository. It hosts Istio's
core components, install artifacts, and sample programs. It includes:

    - [istioctl](istioctl/). This directory contains code for the
[_istioctl_](https://istio.io/latest/docs/reference/commands/istioctl/) command line utility.

    - [operator](operator/). This directory contains code for the
[Istio Operator](https://istio.io/latest/docs/setup/install/operator/).

workloads can talk with each other and obey the Istio configuration resources, but each environment
can use different Istio versions and different configuration defaults.

`istioctl kube-inject` or the automatic sidecar injector are used to select the environment.
In the case of the sidecar injector, the namespace label `istio-env: <NAME_OF_ENV>` is used instead

        - Pod has `istio-init` initContainer - this indicates a pod running its own injection setup.

## Troubleshooting

### Collecting Logs

#### Using `istioctl`/helm

- Set: `values.global.logging.level="cni:debug,ambient:debug"`
- Inspect the pod logs of a `istio-cni` Daemonset pod on a specific node.

#### From a specific node syslog

```yaml
networkGateway: network-1
```

### Migrating from other installation methods

Installations from other installation methods (such as istioctl, Istio Operator, other helm charts, etc) can be migrated to use the new Helm charts
following the guidance below.
