This means that instead of the normal process of your users sending requests to your API, it's **your API** (or your app) that could **send requests to their system** (to their API, their app).

This is normally called a **webhook**.

## Webhooks steps

The process normally is that **you define** in your code what is the message that you will send, the **body of the request**.

  // The set of valid time zone names and the time zone offset is loaded from the system-wide time zone
  // database by the API server during CronJob validation and the controller manager during execution.
  // If no system-wide time zone database can be found a bundled version of the database is used instead.

kubectl create ns istio-system
kubectl apply -f operator/samples/default-install.yaml
```

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.
