k8s中ingress-nginx的rewrite用法其一

目的是访问www.dev.com自动跳转到www.dev.com/login这样的访问写法如下：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: www.dev.com 
  annotations:
    nginx.ingress.kubernetes.io/app-root: /login
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  rules:
  - host: www.dev.com
    http:
      paths:
      - path: /login(/|$)(.*)
        backend:
          serviceName: myapp-v1-svc
          servicePort: 80
