### Enable MultiClusterService in karmada-controller-manager

To enable the MultiClusterService feature in the karmada-controller-manager, run the following command:

```shell
$ kubectl --context karmada-host get deploy karmada-controller-manager -n karmada-system -o yaml | sed '/- --v=4/i \ - --feature-gates=MultiClusterService=true' | kubectl --context karmada-host replace -f -
```

Please note that the MultiClusterService feature is disabled by default and can be enabled using the `--feature-gates=MultiClusterService=true` flag.

If you prefer a more cautious approach, follow these steps:

1. Run `kubectl --context karmada-host edit deploy karmada-controller-manager -n karmada-system`
2. Check if `--feature-gates=MultiClusterService=true` is present in the `spec.template.spec.containers[0].command` field.
3. If not, add `--feature-gates=MultiClusterService=true` to enable the feature.
