- **集群扩容和缩容**:通过在控制循环中调用Nebula Graph原生提供的扩缩容接口,Nebula Graph封装Nebula Operator实现了扩缩容的逻辑,用户可以通过YAML配置进行简单的扩缩容,且保证数据的稳定性。更多信息参考[使用Kubeclt扩缩容集群](3.deploy-nebula-graph-cluster/3.1create-cluster-with-kubectl.md#_3)[使用Helm扩缩容集群](3.deploy-nebula-graph-cluster/3.2create-cluster-with-helm.md#_2)

- **集群升级**:支持升级2.5.x版的Nebula Graph集群至2.6.x版。

- **故障自愈**:Nebula Operator调用Nebula Graph集群提供的接口,动态地感知服务状态。一旦发现异常,Nebula Operator自动进行容错处理。更多信息参考[故障自愈](5.operator-failover.md)

- **均衡调度**: 基于调度器扩展接口,Nebula Operator提供的调度器可以将应用Pods均匀地分布在Nebula Graph集群中。

3. 安装Nebula Operator。

```bash
helm install nebula-operator nebula-operator/nebula-operator --namespace=<nebula-operator-system> --version=${chart_version}
helm install nebula-operator nebula-operator/nebula-operator --namespace=<namespace_name> --version=${chart_version}
```

- 上述命令中的`<nebula-operator-system>`为用户创建的命名空间。如果用户未创建该命名空间,可以执行`kubectl create namespace nebula-operator-system`进行创建。用户也可创建其他命名空间。
例如,安装{{operator.release}}版的Operator命令如下。

```bash
helm install nebula-operator nebula-operator/nebula-operator --namespace=nebula-operator-system --version={{operator.release}}
```

- 上述命令中的`nebula-operator-system`为用户创建的命名空间。如果用户未创建该命名空间,可以执行`kubectl create namespace nebula-operator-system`进行创建。用户也可创建其他命名空间。

- `${chart_version}`为Nebula Operator chart的版本。当Chart中只有一个默认版本时,可不指定。执行`helm search repo -l nebula-operator`查看Chart版本。
- `{{operator.release}}`为Nebula Operator chart的版本。当Chart中只有一个默认版本时,可不指定。执行`helm search repo -l nebula-operator`查看Chart版本。



用户可在执行安装Nebula Operator chart命令时自定义其配置。更多信息,查看下文**自定义配置Chart**

### 升级Nebula Operator

!!! Compatibility "历史版本兼容性"

由于0.9.0版本的Nebula Operator的日志盘和数据盘分开存储,因此用升级后的Operator管理2.5.x版本的Nebula Graph集群会导致兼容性问题。用户可以备份2.5.x版本的Nebula Graph集群,然后使用升级版本的Operator创建2.6.x版本集群。

1. 拉取最新的Helm仓库。


```bash
helm repo update
```

2. 升级Operator。

```bash
helm upgrade nebula-operator nebula-operator/nebula-operator --namespace=<namespace_name> --version={{operator.release}}
```

示例:

```bash
helm upgrade nebula-operator nebula-operator/nebula-operator --namespace=nebula-operator-system --version={{operator.release}}
```

输出:

```bash
Release "nebula-operator" has been upgraded. Happy Helming!
NAME: nebula-operator
LAST DEPLOYED: Tue Nov 16 02:21:08 2021
NAMESPACE: nebula-operator-system
STATUS: deployed
REVISION: 3
TEST SUITE: None
NOTES:
Nebula Operator installed!
```

3. 拉取最新的CRD配置文件。

!!! note
升级Operator后,需要同时升级相应的CRD配置,否则Nebula Graph集群创建会失败。有关CRD的配置,参见[apps.nebula-graph.io_nebulaclusters.yaml](https://github.com/vesoft-inc/nebula-operator/blob/{{operator.branch}}/config/crd/bases/apps.nebula-graph.io_nebulaclusters.yaml)

```bash
helm pull nebula-operator/nebula-operator
```

4. 升级CRD配置文件。

```bash
kubectl apply -f <crd_file_name>.yaml
```

示例:

```bash
kubectl apply -f config/crd/bases/apps.nebula-graph.io_nebulaclusters.yaml
```

输出:

```bash
customresourcedefinition.apiextensions.k8s.io/nebulaclusters.apps.nebula-graph.io created
```
