Traefik 作为一个简单的 Http 反向代理不起作用

【中文标题】Traefik 作为一个简单的 Http 反向代理不起作用

【英文标题】：Traefik as a simple Http Reverse Proxy not working

【发布时间】：2018-08-29 08:19:54

【问题描述】：

我使用 Traefik 作为 HTTP 反向代理。我有两个使用 spring boot 创建的服务器。两台服务器都在端口8081 和8082 上正常工作

Traefik Web UI 在端口8080 中可见。

我想要的是将http://localhost:7070/ 重定向到http://localhost:8081/ 或http://localhost:8082/

traefik.toml 配置文件

loglevel="INFO"

defaultEntryPoints = ["http"]

[entryPoints]
 [entryPoints.http]
 address = ":7070"

[file]

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

[backends]
  [backends.backend1]
  [backends.backend1.LoadBalancer]
  method = "drr"
  [backends.backend1.healthcheck]
  path = "/app/health"
  interval = "60s"

[backends.backend1.servers.server1]
url = "http://127.0.0.1:8081"
weight = 1

[backends.backend1.servers.server2]
url = "http://127.0.0.1:8082"
weight = 1
[api]
[ping]
[docker]

控制台输出

当我从浏览器加载 http://localhost:7070/ 时，它会给出

服务不可用

当我转到 Traefik 健康仪表板时，它会显示

谁能告诉我我在这里做错了什么？我浏览了几篇文章，但找不到正确的答案。

【问题讨论】：

Traefik 文档纯属垃圾。我也想要一个简单的答案。

【参考方案1】：

我想你是在容器中运行 Træfik。

127.0.0.1 -> localhost 在容器内，而不是在本地机器中。

【讨论】：

没有。我在我的本地机器上运行它。我这里没有使用 docker。

为什么最后有一个[docker]，可能是混淆了Traefik？

@Almar 我认为它与--docker 相同，也与--api 相同。这个 TOML 在 traefik 集群中很混乱，应该没有 TOML 吧？

TOML 不是问题，也不会让 Traefik 感到困惑
