Traefik 不保留真实 IP

2024-6-1 • tag-icon

我在使用 Traefik 时遇到问题，我想使用 syslog-ng（docker）从服务器进行日志记录。我有日志，但我有 reverse_proxy 名称，我想要源 IP 而不是 traefik 的名称。我希望保留主机的源 IP。traefik.yml：

global:
  sendAnonymousUsage: false

api:
  dashboard: true
  insecure: true

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    watch: true
    useBindPortIP: true
    exposedByDefault: false

  file:
    filename: /etc/traefik/config.yml
    watch: true

log:
  level: INFO
  format: common

entryPoints:
  http:
    address: ":80"
    http:
      redirections:
        entryPoint:
          to: https
          scheme: https

  https:
    address: ":443"

  udp:
    address: ":514/udp"

  tcp:
    address: ":514"

udp:
  services:
    syslog-ng:
      loadBalancer:
        servers:
        - address: ":514/udp"
tcp:
  services:
    syslog-ng:
      loadBalancer:
        servers:
        - address: ":514"
        forwardedHeaders: true

certificatesResolvers:
  le:
    acme:
      email: [email protected]
      storage: acme.json
      httpChallenge:
        # used during the challenge
        entryPoint: http

syslog-ng.conf：

它就像 NAT 反向，但我不知道在这里我是否可以在 traefik 中找到配置。

谢谢你读我问候

如果我没理解错的话，你只需要在 YML 文件中添加一行：

目标：514
发布：1514
协议：udp
模式：主机<-----
