构建和部署 Kubernetes 控制器

本篇介绍如何使用 ShenYu Kubernetes Controller。

构建

建议参考自定义部署构建自定义网关，在网关的 Maven 依赖中加入 shenyu-kubernetes-controller 的依赖，网关即可集成 kubernetes 控制器。

  1.         <dependency>
  2.             <groupId>org.apache.shenyu</groupId>
  3.             <artifactId>shenyu-spring-boot-starter-k8s</artifactId>
  4.             <version>${project.version}</version>
  5.         </dependency>

也可以直接使用官方构建的 docker 镜像（TODO，未完成）

部署

K8s 部署文件可参考：

  50.       targetPort: 9195
  51.       nodePort: 30095
  52. ---
  53. apiVersion: rbac.authorization.k8s.io/v1
  54. kind: ClusterRole
  55. metadata:
  56.   name: shenyu-ingress-controller
  57. rules:
  58. - apiGroups:
  59.   - ""
  60.   resources:

  64.   - secrets
  65.   - pods
  66.   verbs:
  67.   - get
  68.   - list
  69.   - watch
  70. - apiGroups:
  71.   - networking.k8s.io
  72.   resources:
  73.   - ingresses
  74.   verbs:

  76.   - list
  77.   - watch

  79. apiVersion: rbac.authorization.k8s.io/v1
  80. kind: ClusterRoleBinding
  81. metadata:
  82.   name: shenyu-ingress-controller
  83.   namespace: shenyu-ingress
  84. roleRef:
  85.   apiGroup: rbac.authorization.k8s.io
  86.   kind: ClusterRole
  87.   name: shenyu-ingress-controller
  88. subjects:
  89. - kind: ServiceAccount
  90.   name: shenyu-ingress-controller
  91.   namespace: shenyu-ingress

其中，Service 可以根据实际情况改成 LoadBalancer 类型。
