Add custom headers

  • proxy-set-headers for passing a custom list of headers to the upstream server

  • add-headers To pass the custom headers before sending response traffic to the client

Easier option

Harder option

Changes to the custom header config maps do not force a reload of the ingress-nginx-controllers.

Configure in the controller

In the ingress-nginx-controller configmap or similar, we indicate to the controller which is our configmap that will contain our custom headers. This can be done using 2 keys

Create the configmap

Restart the controller
