Traefik v2：将 http:///servername/foo 重定向到 http://servername:port

Question

我的家庭网络中的 raspberrypi 上有 traefik（2.3.5 版）和其他服务运行。每个服务在同一台机器上的不同端口上运行。我希望 traefik 将调用从子路径重定向到不同的 url。像这样：

http:///myServer/omv --> http://myServer:8000
http:///myServer/heimdall --> http://myServer:8003

但是我无法让它工作。我的路由器没有提供 domain/subdomains 所以我不得不使用子路径。

OMV 在本地安装，因此我创建了一个文件提供程序，这是唯一可用的文件提供程序。我无法找出我的 docker-compose 文件有什么问题，例如海姆达尔

这是 traefik docker-compose.yml:

version: '2'

services:
        traefik:
                image: traefik:latest
                container_name: traefik
                restart: unless-stopped
                security_opt:
                        - no-new-privileges:true
                ports:
                        - 80:80

                        - "traefik.http.routers.traefik.entrypoints=http"
                        - "traefik.http.routers.traefik.rule=PathPrefix(`/api`) || PathPrefix(`/traefik`)" 
                        - "traefik.http.middlewares.traefik-auth.basicauth.users=XXXX:YYYYYYYYYYYYYYYYY"
                        - "traefik.http.routers.traefik.middlewares=traefik-auth,traefik-strip-prefix"

                        - "traefik.http.routers.traefik.service=api@internal"

Traefik.yml:

海姆达尔docker-compose.yml:

version: "2"
services:
        heimdall:
                image: ghcr.io/linuxserver/heimdall
                container_name: heimdall
                environment:
                        - PUID=1000
                        - PGID=1000
                        - TZ=Europe/Berlin
                volumes:
                        - /root/myDockers/heimdall/appdata/config:/config
                ports:
                        - 8003:80
                restart: unless-stopped
                labels:
                        - "traefik.enable=true"
                        - "traefik.hppt.routers.heimdall.entrypoints=http"
                        - "traefik.http.routers.heimdall.rule=PathPrefix(`/heimdall`)"
                        - "traefik.http.routers.heimdall.middlewares=heimdall-redirect"
                        - "traefik.http.middlewares.heimdall-redirect.redirectregex.regex=`^http://myServer/heimdall(.*)`"
                        - "traefik.http.middlewares.heimdall-redirect.redirectregex.replacement=`http://myServer:8003`"
                        - "traefik.http.middlewares.heimdall-redirect.redirectregex.permanent=true"
                        - "traefik.http.services.heimdall.loadbalancer.server.url=`http://myServer:8003`"

当我调用 http:///myServer/heimdall 时没有任何反应，一段时间后我超时了。我认为原因是，traefik 正试图转发到 heimdall 172.31.0.2:80 的 docker 内部网络地址，当然我的客户端无法访问该地址。在 traefik 日志中它指出：特雷菲克 | {"entryPointName":"http","level":"debug","msg":"正在创建服务器 0 http://172.31.0.2:80","routerName":"heimdall@docker","serverName":0,"serviceName":"heimdall","time":"2020-12-13T21:55:02+01:00"}

谁能给我指出正确的方向？

Answer 1

你能勾选“traefik.http.routers.heimdall.rule”的“主机”吗

也许需要这样，

"traefik.http.routers.heimdall.rule=Host(`myServer`) && PathPrefix(`/heimdall`)"

Answer 2

经过进一步 google 的工作，我想我在这个论坛 post 中找到了答案：https://community.traefik.io/t/traefik-v2-1-4-how-to-create-a-static-route-and-redirect-to-a-specific-host-and-port/4637

他们说的是，如果您使用 docker 标签来配置 traefik，则只能路由到 docker 容器本身。对于 docker 容器之外的路由，您需要使用 docker 文件提供程序。这也解释了为什么它对我适用于 OMV 但不适用于 heimdall。
