## Step 3. Update istioctl schema

Istioctl uses a [schema](../../operator/pkg/apis/istio/v1alpha1/values_types.proto) to validate the values. Any changes to
the schema must be added here, otherwise istioctl users will see errors.
Once the schema file is updated, run:

```bash
$ make operator-proto
```

This will regenerate the Go structs used for schema validation.

## Step 4. Update the generated manifests

  optional string patchType = 5;

  // AuditAnnotations is an unstructured key value map set by remote admission controller (e.g. error=image-blacklisted).
  // MutatingAdmissionWebhook and ValidatingAdmissionWebhook admission controller will prefix the keys with
  // admission webhook name (e.g. imagepolicy.example.com/error=image-blacklisted). AuditAnnotations will be provided by

  //   2. If ALL matchConditions evaluate to TRUE, the webhook is called.
  //   3. If any matchCondition evaluates to an error (but none are FALSE):
  //      - If failurePolicy=Fail, reject the request
  //      - If failurePolicy=Ignore, the error is ignored and the webhook is skipped
  //
  // This is an alpha feature and managed by the AdmissionWebhookMatchConditions feature gate.

The operator validates the configuration and automatically detects syntax errors. If you are
using Helm values that are incompatible, the schema validation used in the operator may reject input that is valid for
Helm.
