### Optional: feature-gate

| `DaemonWatchingPod`    | Should each `kruise-daemon` watch pods on the same node      | `true`  | For in-place update with same imageID or env from labels/annotations |
| `CloneSetShortHash`    | Enables CloneSet controller only set revision hash name to pod label | `false` | CloneSet name can not be longer than 54 characters |
| `KruisePodReadinessGate` | Enables Kruise webhook to inject 'KruisePodReady' readiness-gate to all Pods during creation | `false` | The readiness-gate will only be injected to Pods created by Kruise workloads |
| `PreDownloadImageForInPlaceUpdate` | Enables CloneSet controller to create ImagePullJobs to pre-download images for in-place update | `false` | No image pre-download for in-place update |
| `CloneSetPartitionRollback` | Enables CloneSet controller to rollback Pods to currentRevision when number of updateRevision pods is bigger than (replicas - partition) | `false` | CloneSet will only update Pods to updateRevision |
| `ResourcesDeletionProtection` | Enables protection for resources deletion              | `false` | No protection for resources deletion |
| `TemplateNoDefaults` | Whether to disable defaults injection for pod/pvc template in workloads | `false` | Should not close this feature if it has open |
| `PodUnavailableBudgetDeleteGate` | Enables PodUnavailableBudget for pod deletion, eviction           | `false` | No protection for pod deletion, eviction |
| `PodUnavailableBudgetUpdateGate` | Enables PodUnavailableBudget for pod.Spec update                  | `false` | No protection for in-place update |
| `WorkloadSpread`                 | Enables WorkloadSpread to manage multi-domain and elastic deploy  | `false` | WorkloadSpread disabled |

| `StatefulSetAutoDeletePVC`       | Enables policies controlling deletion of PVCs created by a StatefulSet  | `false` | No deletion of PVCs by StatefulSet |

If you want to configure the feature-gate, just set the parameter when install or upgrade. Such as:

```bash
$ helm install kruise https://... --set featureGates="ResourcesDeletionProtection=true\,PreDownloadImageForInPlaceUpdate=true"
...
```

If you want to enable all feature-gates, set the parameter as `featureGates=AllAlpha=true`.

### Optional: the local image for China

If you are in China and have problem to pull image from official DockerHub, you can use the registry hosted on Alibaba Cloud:

```bash
$ helm install kruise https://... --set  manager.image.repository=openkruise-registry.cn-hangzhou.cr.aliyuncs.com/openkruise/kruise-manager
...
```
