Traefik 权重分流

不同于 Istio，Traefik需要每个dep对应各自的 service

这里我们分别创建3个不同的 service 使用clusterip

创建 traefik service

apiVersion: traefik.containo.us/v1alpha1
kind: TraefikService
metadata:
  name: lizhets
  namespace: version
spec:
  weighted:
    services:
      - name: ver1
        weight: 3  # 定义权重
        port: 80
        kind: Service  # 可选，默认就是 Service
      - name: ver2
        weight: 1
        port: 80

创建 IngressRoute

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: lizheingressroute
  namespace: version
spec:
  entryPoints:
    - web
  routes:
  - match: Host(`ts.lizhe.com`)
    kind: Rule
    services:
    - name: lizhets
      kind: TraefikService

for i in `seq 20`; do curl http://ts.lizhe.com:8000/helloworld.html;echo "" ;done
