traefik 不会将请求转发到“正常”（非 docker）后端答案

【问题标题】：traefik does not forward requests to a "normal" (non-docker) backendtraefik 不会将请求转发到“正常”（非 docker）后端
【发布时间】：2018-01-12 09:34:20
【问题描述】：

在 docker 模式下测试 traefik - 一切正常。现在我需要使用“普通”后端，即从 traefik 控制的端口 88 将请求转发到端口 8080。但它没有按预期工作。

curl -v -H Host:myhost 127.0.0.1:88（未找到，预期 whoami 答案）

$ curl -v -H Host:myhost  127.0.0.1:88
* Rebuilt URL to: 127.0.0.1:88/
*   Trying 127.0.0.1...
* Connected to 127.0.0.1 (127.0.0.1) port 88 (#0)
> GET / HTTP/1.1
> Host:myhost
> User-Agent: curl/7.47.0
> Accept: */*

traefik 被执行为./traefik2 --logLevel=DEBUG --debug -c traefik.toml
后端是sudo docker service create -d --name whoami --constraint=node.role==manager --publish 8080:80 --replicas 1 emilevauge/whoami

有什么想法吗？

traefik.toml

debug=true
logLevel = "DEBUG"

[traefikLog]
filePath = "tl.txt"

[accessLog]
filePath = "al.txt"

[entryPoints]
  [entryPoints.http]
  address = ":88"

[frontends]
  [frontends.frontend1]
  backend = "backend1"
  [frontends.frontend1.routes.backend1]
  rule = "Host:myhost"

[backends]
  [backends.backend1]
    [backends.backend1.servers.server1]
    url = "http://127.0.0.1:8080"

curl 127.0.0.1:8080（docker emilevauge/whoami，按预期工作）

$ curl 127.0.0.1:8080

请solved by Idez。配置必须是这样的（[file] 部分丢失）：

defaultEntryPoints = ["http"]

debug=true
logLevel = "DEBUG"

[traefikLog]
filePath = "tl.txt"

[accessLog]
filePath = "al.txt"

[entryPoints]
  [entryPoints.http]
  address = ":88"

[file]

[backends]
  [backends.backend1]
    [backends.backend1.servers.server1]
    url = "http://127.0.0.1:8080"


[frontends]
  [frontends.frontend1]
  backend = "backend1"
    [frontends.frontend1.routes.test_1]
    rule = "Host:myhost"
