弹性网卡​

如果集群网络模式是 Global Router，且启用了 VPC-CNI (两种模式混用)，Pod 调度到普通节点默认使用 Global Router 模式，如需要 Pod 用 VPC-CNI (弹性网卡)，需显式指定：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
      annotations:
        tke.cloud.tencent.com/networks: tke-route-eni
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          resources:
            requests:
              tke.cloud.tencent.com/eni-ip: "1"
            limits:
              tke.cloud.tencent.com/eni-ip: "1"

EIP​

更详细的说明请参考 Pod 绑 EIP。

声明使用 EIP​

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
      annotations:
        tke.cloud.tencent.com/networks: "tke-route-eni" # 如果集群网络是 GlobalRouter + VPC-CNI 混用，用此注解需要显式指定 Pod 使用 VPC-CNI
        # 指定 EIP 属性，具体字段参考 CLB 的 AllocateAddresses 接口文档：https://cloud.tencent.com/document/api/215/16699#2.-.E8.BE.93.E5.85.A5.E5.8F.82.E6.95.B0
        tke.cloud.tencent.com/eip-attributes: '{"Bandwidth":"100", "ISP":"BGP", "InternetMaxBandwidthOut":50, "InternetChargeType":"TRAFFIC_POSTPAID_BY_HOUR"}'
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          resources: # 声明 EIP 资源，用于调度 (节点能绑定的 EIP 数量有限)
            limits:
              tke.cloud.tencent.com/eni-ip: "1"
              tke.cloud.tencent.com/eip: "1"
            requests:
              tke.cloud.tencent.com/eni-ip: "1"
              tke.cloud.tencent.com/eip: "1"
