Traefik 向除仪表板以外的所有地方显示 404 - Metallb

Question

我尝试使用 traefik 设置入口，但没有成功。我不会仅仅使用 TLS 端口 80。我有一个端口为 8080 的服务。如果我从集群内部 curl 到该服务，它运行良好。我得到 HTTP/200。但如果我从外部连接到他的路径，它就不起作用了。 Traefik 仪表板在端口 8080

上运行良好

我正在使用以下设置

Traefik：1.7.7

我在端口 8080 上有一个运行服务，我为它创建了一个入口规则。这是一个测试服务

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: webmust-ing
  namespace: default
  annotations:
    kubernetes.io/ingress.class: traefik
spec:
  rules:
    - http:
        paths:
        - path: /helloservice
          backend:
            serviceName: hellok8s-service
            servicePort: 8080

我通过 curl 到 /helloservice 或尝试从浏览器打开得到 404

curl -v http://10.24.33.32/helloservice
curl -v http://10.24.33.32:8080/helloservice

我如果直接在集群内 curl 到服务的 ip 地址，我得到 200/OK

curl -v http://10.100.168.2:8080

NAME                      TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                       AGE

最后，我通过以下入口更改解决了问题。

annotations: 
    ingress.kubernetes.io/protocol: http 
    traefik.ingress.kubernetes.io/rule-type: PathPrefixStrip
