Question

我有一个Kubernetes集群，目前可与haproxy入口控制器配合使用（并且工作正常）。我正在尝试将traefik作为入口控制器，但即使对于使用haproxy入口控制器时未返回404的请求，它也始终返回404。

traefik config -- 
[entryPoints]
[entryPoints.http]
    address = "S.S.S.S:80"
[entryPoints.https]
    address = "S.S.S.S:443"

（简化的）Ingress对象如下所示：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
    annotations:
    kubernetes.io/ingress.class: nginx
spec:
    rules:
    - host: apifrontend.example.com
    http:
        paths:
        - backend:
            serviceName: apifrontend-web
            servicePort: 80
        path: /

感谢您的任何指示。

Answer 1

您的Ingress对象包含一个指定Nginx的Ingress类注释：

kubernetes.io/ingress.class: nginx

这会导致Traefik忽略此类对象。您需要做的是将nginx替换为traefik或完全删除注释。另请参阅Traefik documentation in this regard。

Traefik作为入口控制器始终返回404
