How can i get the traefik controller config and some question about ingress path

Question

My ingress controller is traefik, I want to configure a domain name in ingress with multiple paths for different services.but When I configured and reapply it. I can only access the service corresponding to the root of the domain name, while the other services corresponding to the path are all 404 there is my ingress config:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: web-ingress
  namespace: runsdata
  annotations:
    kubernetes.io/ingress.class: "traefik"
spec:
  tls:
  - secretName: traefik-cert
  rules:
  - host: testenv.runsdata.com
    http:
      paths:
      - backend:
          serviceName: nginx-svc
          servicePort: 8088
  - host: testenv.runsdata.com
    http:
      paths:
      - backend:
          serviceName: traefik-web-ui
          servicePort: 8006
        path: /traefik

I can access the nginx-svc by the url：https://testenv.runsdata.com:12840/ . But I can't access the traefik-web-ui service by the url: https://testenv.runsdata.com:12840/traefik. Is there anything wrong with my configuration. Another question is how can I see the rules that ingress maps to traefik.I want to see if the mapping is correct. I exec the command kubectl exec -it traefik-ingress-controller-5c5dc68dd4-jxk84 /bin/bash. I wanted to go inside the container and have a look.But it seems that there is no command installed, the command does not exist

Since traefik USES the host route by default, So we just only need to specify it use the path route in annotations like below

annotations:
    kubernetes.io/ingress.class: "traefik"
    traefik.ingress.kubernetes.io/rule-type: PathPrefixStrip
