How to add a unique request ID header to Traefik

Question

In Traefik, is it possible to add a unique Request ID header to requests? I'd like to be able to correlate access logs with logs from backend services.

Answer 1

AFAIK there is no support for it, however here is a funcional workaround in Traefik 2.3.6:

# static config

    samplingParam = 0
    traceContextHeaderName = "X-Correlation-Id"
