带有 docker 后端的 Traefik 导致网关错误

Question

我设置了一个 debian 服务器，在其中安装了 docker 和 docker-compose。

我在 sudo 用户的家中创建了一个具有以下层次结构的文件夹：

~/docker-project
      - docker-compose.yml
      - /traefik/traefik.toml

我做了docker-compose up -d一切都开始了我可以访问 traefik.mydomain.com 与其他子域一样具有有效的 ssl 证书。但是，如果我转到我的任何子域以访问我的 dockerized Web 服务，我会在浏览器中收到一条错误的网关消息。如果我转到我的服务器 IP 地址并输入正确的端口，我会看到我的网络服务运行良好。

所以我想我在配置 docker / traefik 关系时犯了一个错误，但我找不到在哪里。

这是我的traefik.toml：

defaultEntryPoints = ["http", "https"]

################################################################
# Web configuration backend
################################################################
[web]
address = ":8080"
[web.auth.basic]
# User: user | Password: password
users = ["user:hashedpassword"]

################################################################
# Entry-points configuration
################################################################
[entryPoints]
  [entryPoints.http]
    address = ":80"
    [entryPoints.http.redirect]
      entryPoint = "https"
  [entryPoints.https]
    address = ":443"
    [entryPoints.https.tls]

################################################################
# Docker configuration backend
################################################################
[docker]
domain = "mydomain.com"
watch = true
exposedbydefault = false

################################################################
# Let's encrypt
################################################################
[acme]
email = "my-email@mail.com"
storageFile = "/etc/traefik/acme.json"
onDemand = false
onHostRule = true
entryPoint = "https"

这是我的docker-compose.yml：

Answer 1

因此，由于出色的 traefik 松弛频道，我设法得到了答案！

所以我的容器都在同一个 docker 网络中，包括我的 traefik 容器。

问题是我将所有容器端口映射为可从主机访问。

相反，我应该只将 traefik 端口映射到主机，并且只公开我的 Web 服务容器的端口，以便 traefik 可以在它们所在的 docker 网络中监听它们。

更改： -添加公开 -更改traefik.port

我只需要在我的 docker-compose.yml 中做这个改变：

version: '2'
services:

  traefik:
    restart: always
    image: traefik
    container_name: traefik
    ports:

      - '8080:8080'
    labels:
      - 'traefik.enable=true'
      - 'traefik.docker.network=dockerplatform_default'
      - 'traefik.port=8080'
      - 'traefik.frontend.rule=Host:traefik.mydomain.com'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
