17.3.5. 通过路由标签（label）配置 Ingress Controller 分片

流程

1. 编辑 router-internal.yaml 文件：

   # cat router-internal.yaml
   apiVersion: v1
   items:
   - apiVersion: operator.openshift.io/v1
     kind: IngressController
     metadata:
       name: sharded
       namespace: openshift-ingress-operator
     spec:
       domain: <apps-sharded.basedomain.example.net>
       nodePlacement:
         nodeSelector:
           matchLabels:
             node-role.kubernetes.io/worker: ""
       routeSelector:
         matchLabels:
           type: sharded
     status: {}
   kind: List
   metadata:
     resourceVersion: ""
     selfLink: ""

   Copy to Clipboard Toggle word wrap

2. 应用 Ingress Controller router-internal.yaml 文件：

   # oc apply -f router-internal.yaml

   Copy to Clipboard Toggle word wrap

   Ingress Controller 选择具有 type: sharded 标签的任意命名空间中的路由。
