Service

测试 Service

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  type: ClusterIP
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx

CLB 直连 Pod

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
  annotations:
    # 显式声明使用直连
    service.cloud.tencent.com/direct-access: "true"
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx

使用已有 CLB

使用已有 CLB

让 Service 使用指定已经创建好的 CLB:

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
  annotations:
    # 指定要已有的 CLB ID
    service.kubernetes.io/tke-existed-lbid: "lb-********"
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx

多个 Service 复用同一个 CLB

多个 Service 可以使用同一个 CLB (前提是端口不冲突):

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
  annotations:
    # 指定要已有的 CLB ID
    service.kubernetes.io/tke-existed-lbid: "lb-********"
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx

apiVersion: v1
kind: Service
metadata:
  name: nginx2
  labels:
    app: nginx2
  annotations:
    # 指定要已有的 CLB ID
    service.kubernetes.io/tke-existed-lbid: "lb-********"
spec:
  type: LoadBalancer
  ports:
    - port: 8080
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx2

指定 CLB 属性

内网 CLB

默认创建的 CLB 是公网类型，如果要内网类型，需传入子网 ID：

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
  annotations:
    # 指定子网 ID
    service.kubernetes.io/qcloud-loadbalancer-internal-subnetid: subnet-********
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx

多可用区

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
  annotations:
    # 指定主可用区和备可用区
    service.kubernetes.io/service.extensiveParameters: '{ "MasterZoneId": "ap-guangzhou-4", "SlaveZoneId": "ap-guangzhou-8" }'
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx

指定 VIP

指定 CLB 要使用的 VIP（误删恢复时很有用），前提是 VIP 还没有被占用:

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
  annotations:
    # 指定主可用区和备可用区
    service.kubernetes.io/service.extensiveParameters: '{ Vip: "1.1.1.1" }'
spec:
  type: LoadBalancer
  ports:
    - port: 80
      protocol: TCP
      targetPort: 80
  selector:
    app: nginx
