Traefik 的 access.log 中缺少用户代理

问题描述

我已将 Traefik 2.3.1 配置为将访问日志写入文件。但是日志缺少用户代理（浏览器、操作系统信息）。

它是否可以配置？

Traefik 从 docker-compose.yml 运行：

version: '3.4'

services:
  proxy:
    image: traefik:2.3.1 
    command:
      - "--providers.docker=true"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - ./traefik/traefik.toml:/traefik.toml:ro
      - ./logs/traefik:/logs/traefik
    ports:
      - "80:80" 
      - "443:443"
    restart: unless-stopped

来自 traefik.toml 的一些行：

[accessLog]
  filePath = "/logs/traefik/access.log"
  bufferingSize = 100 

日志如下所示：

3.22.235.211 - - [01/Feb/2021:15:42:41 +0000] "GET /.env HTTP/1.1" 404 555 "-" "-" 367 "site@docker" "http://172.18.0.4:8000" 1ms

nginx 在 Traefik 后面运行的日志：

谢谢

解决方法

默认情况下，traefik 不会在其访问日志中记录标头。你必须添加它们。查看文档的 this part。

我改变了 traefik.toml 作为 tetram 指出它开始工作：

[accessLog]
  filePath = "/logs/traefik/access.log"
  bufferingSize = 100  
  [accessLog.fields.headers.names]
    "User-Agent" = "keep"
