Z. B. `pip install email-validator`
oder `pip install pydantic[email]`.

### Step 3. Update istioctl schema

Istioctl uses a [schema](../../operator/pkg/apis/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
```
