如何向Traefik添加唯一的请求ID标头

Question

在Traefik中，是否可以向请求添加唯一的请求ID标头？我希望能够将访问日志与后端服务的日志相关联。

Answer 1

AFAIK 不支持它，但这是 Traefik 2.3.6 中的一个功能性解决方法：

# static config

...

[tracing]
  # Workaround for the non support of Correlation/Request Id Header

  [tracing.jaeger]
    samplingParam = 0
    traceContextHeaderName = "X-Correlation-Id"
