To regenerate the manifests, run:

```bash
$ make copy-templates update-golden
```

## Step 5. Create a PR using outputs from Steps 1 to 4

  // Example: when this is set to 30%, the old ReplicaSet can be scaled down to 70% of desired pods
  // immediately when the rolling update starts. Once new pods are ready, old ReplicaSet
  // can be scaled down further, followed by scaling up the new ReplicaSet, ensuring
  // that the total number of pods available at all times during the update is at
  // least 70% of desired pods.

Istio's helm charts come with a common `openshift` profile that can be used during installation.

The installation process using the Helm charts is as follows:

  #
  # To enable the PodDisruptionBudget, configure it by specifying the
  # `minAvailable` or `maxUnavailable`. For example, to set the
  # minimum number of available replicas to 1, you can update this value as follows:
  #
  # podDisruptionBudget:
  #   minAvailable: 1
  #
  # Or, to allow a maximum of 1 unavailable replica, you can set:
  #
  # podDisruptionBudget:
  #   maxUnavailable: 1
  #

  // it never skips the webhook.
  //
  // For example, to run the webhook on any objects whose namespace is not
  // associated with "runlevel" of "0" or "1";  you will set the selector as
  // follows:
  // "namespaceSelector": {
  //   "matchExpressions": [
  //     {
  //       "key": "runlevel",
  //       "operator": "NotIn",
  //       "values": [
