Add HTTP headers while running Traefik as Ingress controller

3/8/2018

I have an application running in K8S, with Traefik as load balancer as an Ingress controller. While I ca setup easily Traefik for redirection, I need to add specific HTTP headers to all queries going through Traefik.

Is there any way to do this with Traefik?

Cheers, Olivier

Yes. You need to add specific annotation from K8S in the YAML for Ingress:

ingress.kubernetes.io/custom-request-headers: X-ProxyScheme:HERE_IS_MY_SCHEME||X-ProxyHost:HERE_IS_MY_HOST
ingress.kubernetes.io/proxy-headers: X-ProxyScheme,X-ProxyHost,X-ProxyPort

As shown, if you need multiple custom headers, you must pipe them with ||. And you need to "enable" them with annotation ingress.kubernetes.io/proxy-headers
