自定义路由¶

可以在创建 Pod 时通过 Annotations 来指定需要配置的路由，如下所示：

apiVersion: v1
kind: Pod
metadata:
  name: custom-routes
  annotations:
    ovn.kubernetes.io/routes: |
      [{
        "dst": "192.168.0.101/24",
        "gw": "10.16.0.254"
      }, {
        "gw": "10.16.0.254"
      }]
spec:
  containers:
  - name: nginx
    image: docker.io/library/nginx:alpine

dst 字段为空表示修改默认路由。

如果工作负载为 Deployment、DaemonSet 或 StatefulSet，对应的 Annotation 需要配置在资源的 .spec.template.metadata.annotations 中，示例如下：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: custom-routes
  labels:
    app: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
      annotations:
        ovn.kubernetes.io/routes: |
          [{
            "dst": "192.168.0.101/24",
            "gw": "10.16.0.254"
          }, {
            "gw": "10.16.0.254"
          }]
    spec:
      containers:
      - name: nginx
        image: docker.io/library/nginx:alpine
