调度

调度到超级节点

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      # 使用 nodeSelector 显式指定调度到超级节点
      nodeSelector:
        node.kubernetes.io/instance-type: eklet
      containers:
        - name: nginx
          image: nginx:latest

调度指定机型

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      # 使用  nodeSelector 显式指定调度到 SA2.MEDIUM8 机型的节点
      nodeSelector:
        node.kubernetes.io/instance-type: SA2.MEDIUM8
      containers:
        - name: nginx
          image: nginx:latest

网卡和 IP

声明弹性网卡(VPC-CNI)

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，如需使用 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"

声明使用EIP(弹性公网IP)

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
      annotations:
        # 指定 EIP 属性(仅在超级节点支持)，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
        eks.tke.cloud.tencent.com/eip-attributes: '{"InternetMaxBandwidthOut":100, "InternetChargeType":"TRAFFIC_POSTPAID_BY_HOUR"}'
    spec:
      containers:
        - name: nginx
          image: nginx:latest

保留EIP

apiVersion: apps/v1
kind: StatefulSet
metadata:
  labels:
    app: nginx
  name: nginx
spec:
  serviceName: ""
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      annotations:
        eks.tke.cloud.tencent.com/eip-attributes: '{"InternetMaxBandwidthOut":50, "InternetChargeType":"TRAFFIC_POSTPAID_BY_HOUR"}'
        eks.tke.cloud.tencent.com/eip-claim-delete-policy: "Never" # 声明要保留 EIP（Pod 重建后保持 EIP 不变），仅支持 StatefulSet
      labels:
        app: nginx
    spec:
      nodeSelector:
        node.kubernetes.io/instance-type: eklet
      containers:
        - name: nginx
          image: nginx:latest
          command:
            - sleep
            - infinity
