traefik 返回 404 无条件转发到后端

Question

我想无条件地将所有请求转发到后端，但是当我尝试访问它时，我一直收到 404。这是我的配置。

docker-compose.yml

version: '3.3'
services:
  load-balancer:
    image: traefik:1.5-alpine
    ports:
      - 8080:80
    volumes:
      - ./traefik:/etc/traefik
  server1:
    build: server1
    ports:
      - 8081:80

traefik.toml

defaultEntryPoints = ["http"]
debug = true
logLevel = "DEBUG"
[accessLog]

[entryPoints.http]
address = ":80"

[frontends.dummy]
backend = "dummy"
entrypoints = ["http"]
[frontends.dummy.routes.all]
rule = "PathPrefix:/"

[backends.dummy.servers.server1]
url = "http://server1:80"

我可以从 localhost:8081 和 load-balancer 容器内的 http://server1 毫无问题地访问 server1。但是 localhost:8080 一直返回 404

最后的访问日志来自命令

curl localhost:8080                                                                                                                                                                                                                                               

它返回了

404 page not found

我不想使用 docker 后端，只想让 traefik 从容器中执行常规的循环。我想知道这是否可能？

好的，在加入 slack 之后，Machael Matul 指出您将需要[文件] 在入口点后某处声明

[file]

为了让后端工作，它必须在前端的路由声明之前。示例:

[frontends]
  [frontends.frontend1]
  backend = "buffalo"
    [frontends.frontend1.routes.web]
    rule = "Host:xyz.com"
  entrypoints = ["http","https"]

完整示例:

debug = true
logLevel = "DEBUG"
defaultEntryPoints = ["https","http"]

[accessLog]

[web]
address = ":8080"
  [web.auth.basic]
  users = ["admin:md5hashedpassword"]

[acme]
  email = "info@xyz.com"
  storage = "/acme.json"
  entryPoint = "https"
  OnHostRule = true
  [acme.httpChallenge]
    entryPoint = "http"

[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"

  [entryPoints.https]
  address = ":443"
  [entryPoints.https.tls]

[file]
watch = true

[backends]
  [backends.buffalo]
    [backends.buffalo.loadbalancer.stickiness]
    [backends.buffalo.servers.server1]
    url = "http://node1:3000"

    [backends.buffalo.servers.server2]
    url = "http://node2:3000"

  [backends.backendNginx]
    [backends.backendNginx.loadbalancer.stickiness]
    [backends.backendNginx.servers.server1]
    url = "http://nginx1:8080"

    [backends.backendNginx.servers.server2]
    url = "http://nginx2:8080"

  [backends.ai6forum]
    [backends.ai6forum.loadbalancer.stickiness]
    [backends.ai6forum.servers.server1]
    url = "http://10.140.0.9:80"

[frontends]
  [frontends.frontend1]
  backend = "buffalo"
    [frontends.frontend1.routes.web]
    rule = "Host:xyz.com"
  entrypoints = ["http","https"]
  passHostHeader = true
  passTLSCert = true
  priority = 10

  [frontends.nginx]
  backend = "backendNginx"
    [frontends.nginx.routes.web]
