`CmdAdd` is triggered when there is a new pod created. This runs on the node, in a chain of CNI plugins - Istio is
run after the main CNI sets up the pod IP and networking.

1. Check k8s pod namespace against exclusion list (plugin config)
    - Config must exclude namespace that Istio control-plane is installed in (TODO: this may change, exclude at pod level is sufficient and we may want Istiod and other istio components to use ambient too)

In the case of the sidecar injector, the namespace label `istio-env: <NAME_OF_ENV>` is used instead
of the conventional `istio-injected: true`. The name of the environment is defined as the namespace
where the corresponding control plane components (config, discovery, auto-injection) are running.
In the examples below, by default this is the `istio-control` namespace. Pod annotations can also
be used to select a different 'environment'.

index*       (string)             Elasticsearch index to store/update events, index is auto-created
format*      (namespace*|access)  'namespace' reflects current bucket/object list and 'access' reflects a journal of object operations, defaults to 'namespace'
queue_dir    (path)               staging dir for undelivered messages e.g. '/home/events'

The script below can handle this for you. Replace `RELEASE` and `NAMESPACE` with the name and namespace of the release:

```console
KINDS=(service deployment)
RELEASE=istio-ingressgateway
NAMESPACE=istio-system
for KIND in "${KINDS[@]}"; do
    kubectl --namespace $NAMESPACE --overwrite=true annotate $KIND $RELEASE meta.helm.sh/release-name=$RELEASE

This installs the controller into the cluster in the istio-operator namespace. The controller in turns installs
the Istio control plane into the istio-system namespace by default.

### Controller (running locally)

1. Set env $WATCH_NAMESPACE (default value is "istio-system") and $LEADER_ELECTION_NAMESPACE (default value is "istio-operator")

1. Create the `WATCH_NAMESPACE` and `LEADER_ELECTION_NAMESPACE` if they are not created yet.

```bash

Chroot allows user based namespace isolation on many standard Linux deployments.

## 1. Prerequisites

- Familiarity with [chroot](http://man7.org/linux/man-pages/man2/chroot.2.html)
- Chroot installed on your machine.

## 2. Install MinIO in Chroot

init files creation process and is subsequently stored in the wheel file after
the build. It also contains a few paths that cannot be directly imported. These
paths point to attributes or sub-modules within a module's namespace, but they
don't correspond to an actual file or directory on the filesystem. The list of
such paths is stored in the packages_for_skip variable and will be skipped
during the test.

##### How to Build

```

```
KEY:
etcd  federate multiple clusters for IAM and Bucket DNS

ARGS:
endpoints*       (csv)       comma separated list of etcd endpoints e.g. "http://localhost:2379"
path_prefix      (path)      namespace prefix to isolate tenants e.g. "customer1/"
coredns_path     (path)      shared bucket DNS records, default is "/skydns"
client_cert      (path)      client cert for mTLS authentication

and set `networkPolicy.enabled` to `true`.

For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting
the DefaultDeny namespace annotation. Note: this will enforce policy for *all* pods in the namespace:

```
kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
```

To install the chart with the release name `istiod`:

```console
kubectl create namespace istio-system
helm install istiod istio/istiod --namespace istio-system
```

## Uninstalling the Chart

To uninstall/delete the `istiod` deployment:

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