Kubernetes Ingress之traefik版本更新异同点

一、相同点

• 1、与IngressRoute不同命名空间的service依然不能为其查询后端服务

---

二、差异点

• 1、traefik 2.0取消annotations方式进行路径路由

annotations:
  traefik.frontend.rule.type:pathprefixstrip

• 2、traefik 2.0在没有定义中间件Middleware，而直接使用match.PathPrefix()是不能直接提供路径路由功能的

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: stripprefix
  namespace: foo

spec:
  stripPrefix:
    prefixes:
      - /stripit

---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: ingressroutebar

spec:
  entryPoints:
    - web
  routes:
  - match: Host(`bar.com`) && PathPrefix(`/stripit`)
    kind: Rule
    services:
    - name: whoami
      port: 80
    middlewares:
    - name: stripprefix
      namespace: foo
