## Nebula Operator

Nebula Operator (Operator for short) is a tool to automate the deployment, operation, and maintenance of Nebula Graph clusters on Kubernetes. Building upon the excellent scalability mechanism of Kubernetes, Nebula Graph introduced its operation and maintenance knowledge into the Kubernetes system, which makes Nebula Graph a real cloud-native graph database.

- **Scale clusters**: Nebula Operator calls Nebula Graph's native scaling interfaces in a control loop to implement the scaling logic. You can simply perform scaling operations with YAML configurations and ensure the stability of data. For more information, see [Scale clusters with Kubectl](3.deploy-nebula-graph-cluster/3.1create-cluster-with-kubectl.md) or [Scale clusters with Helm](3.deploy-nebula-graph-cluster/3.2create-cluster-with-helm.md).

- **Cluster Upgrade**: Nebula Operator supports cluster upgrading from version {{operator.upgrade_from}} to version {{operator.upgrade_to}}.

- **Self-Healing**: Nebula Operator calls interfaces provided by Nebula Graph clusters to dynamically sense cluster service status. Once an exception is detected, Nebula Operator performs fault tolerance. For more information, see [Self-Healing](5.operator-failover.md).

| 1.0.0| 3.0.0 ~ 3.1.x |
| 0.9.0| 2.5.x ~ 2.6.x |
|0.8.0|2.5.x|

!!! Compatibility "Legacy version compatibility"

- The 1.x version Nebula Operator is not compatible with Nebula Graph of version below v3.x.
- Starting from Nebula Operator 0.9.0, logs and data are stored separately. Using Nebula Operator 0.9.0 or later versions to manage a Nebula Graph 2.5.x cluster created with Operator 0.8.0 can cause compatibility issues. You can backup the data of the Nebula Graph 2.5.x cluster and then create a 2.6.x cluster with Operator 0.9.0.

### Feature limitations

Nebula Operator currently only supports manual scaling of Nebula Graph clusters, and does not support automatic scaling of Nebula Graph clusters.

### Update Nebula Operator
After installing Nebula Operator, you can update it by modifying the parameter values in the `${HOME}/nebula-operator/charts/nebula-operator/values.yaml` file.
1. Clone the Nebula Operator repository to your local server.
1. Update the information of available charts locally from chart repositories.
```bash
git clone https://github.com/vesoft-inc/nebula-operator.git
```
helm repo update
```
2. Modify the parameter values in `${HOME}/nebula-operator/charts/nebula-operator/values.yaml`.
2. Update Nebula Operator by passing configuration parameters via `-set` or `-values` flag.
- `--set`：Overrides values using the command line.
- `--values` (or `-f`)：Overrides values using YAML files.
For configurable items, see the above-mentioned section **Customize Helm charts**.
For example, to disable the AdmissionWebhook ( AdmissionWebhook is enabled by default), run the following command:
3. Run the following command to update Nebula Operator.
```bash
helm upgrade nebula-operator nebula-operator/nebula-operator --namespace=<namespace_name> -f ${HOME}/nebula-operator/charts/nebula-operator/values.yaml
helm upgrade nebula-operator nebula-operator/nebula-operator --namespace=nebula-operator-system --version={{operator.release}} --set admissionWebhook.create=false
```
`<namespace_name>` is a user-created namespace name. Pods related to the nebula-operator repository are in this namespace.
For more information, see [Helm upgrade](https://helm.sh/docs/helm/helm_update/).
