## Step 2. Update the istioctl/Operator values

If you are modifying the `gateway` chart, you can stop here.
All other charts, however, are exposed by `istioctl` and need to follow the steps below.

The charts in the `manifests` directory are used in istioctl to generate an installation manifest.

  # `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
  #

```console
kubectl create namespace istio-system
```

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:

  // interpreted in the context of the specific consumer.
  optional int32 port = 3;

  // appProtocol represents the application protocol for this port.
  // This field follows standard Kubernetes label syntax.
  // Un-prefixed names are reserved for IANA standard service names (as per
  // RFC-6335 and https://www.iana.org/assignments/service-names).
