问题

可以更改Traefik仪表板的默认API路径从/api到其他路径吗？我找到了这个链接，但不幸的是它不再可用。

在我的情况下，Traefik充当Kubernetes Ingress控制器，并且我正在使用基于路径的路由。问题是现在我不能使用/api来供我的微服务使用，因为仪表板已经使用了这个路径（这些端点）。

仪表板的Ingress配置：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-web-ui
  annotations:
    kubernetes.io/ingress.class: traefik 
    traefik.ingress.kubernetes.io/priority: "2"
spec:
  rules:
  - http:
      paths:
      - path: /dashboard
        backend:
          serviceName: traefik-web-ui
          servicePort: http
      - path: /api <-- 需要使仪表板的API可用
        backend:
          serviceName: traefik-web-ui
          servicePort: http 

一个微服务的Ingress配置：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: backend
  annotations:
    kubernetes.io.ingress.class: traefik 
    traefik.ingress.kubernetes.io/priority: "999"
spec:
  rules:
  - http:
      paths:
      - path: /apis/ <-- 我更愿意在这里使用/api
        backend:
          serviceName: {{ include "my-backend.fullname" . }}
          servicePort: http 

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: traefik-web-ui
  annotations:
    kubernetes.io/ingress.class: traefik 
    traefik.ingress.kubernetes.io/priority: "2"
spec:
  rules:
  - http:
      paths:
      - path: /dashboard
        backend:
          serviceName: traefik-web-ui
          servicePort: http
      - path: /api <-- needed to make dashboard's api available
        backend:
          serviceName: traefik-web-ui
          servicePort: http 

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: backend
  annotations:
    kubernetes.io/ingress.class: traefik 
    traefik.ingress.kubernetes.io/priority: "999"
spec:
  rules:
  - http:
      paths:
      - path: /apis/ <-- i'd rather use /api here
        backend:
          serviceName: {{ include "my-backend.fullname" . }}
          servicePort: http

以下是翻译好的部分：

你可以按照以下方式进行自定义：

defaultEntryPoints = ["http"]

[entryPoints]
  [entryPoints.http]
  address = ":80"

  [entryPoints.foo]
  address = ":8080"

  [entryPoints.bar]
  address = ":8081"

# 激活 API 和仪表板
[api]
entryPoint = "bar"
dashboard = true

  [backends]
    [backends.backend1]
      [backends.backend1.servers.server1]
      url = "http://127.0.0.1:8081"

  [frontends]
    [frontends.frontend1]
    entryPoints = ["foo"]
    backend = "backend1"
      [frontends.frontend1.routes.test_1]
      rule = "PathPrefixStrip:/yourprefix;PathPrefix:/yourprefix"

You can customize it as below 

    defaultEntryPoints = [&quot;http&quot;]
    
    [entryPoints]
      [entryPoints.http]
      address = &quot;:80&quot;
    
      [entryPoints.foo]
      address = &quot;:8080&quot;
    
      [entryPoints.bar]
      address = &quot;:8081&quot;
    
    # Activate API and Dashboard
    [api]
    entryPoint = &quot;bar&quot;
    dashboard = true
