This article introduces how to use ShenYu Ingress Controller.

## Construct

It is recommended to refer to [Custom Deployment](../../deployment/deployment-custom.md) to build a custom gateway, add the shenyu-kubernetes-controller dependency to the Maven dependency of the gateway, and the gateway can integrate the kubernetes controller.

```xml
         <dependency>
             <groupId>org.apache.shenyu</groupId>
             <artifactId>shenyu-spring-boot-starter-k8s</artifactId>
             <version>${project.version}</version>
         </dependency>
```

You can also directly use the officially built docker image (TODO, unfinished)

## deployment

K8s deployment files can refer to:

```yaml

Among them, Service can be changed to `LoadBalancer` type according to the actual situation.
