[nginx] configmap config server-tokens=false only removes version

[stp-ip]

The configmap configuration for nginx "server-tokens" is only removing the version instead of the whole nginx Server header. I would expect it to actually remove it completely.

Actually this is a behaviour of NGINX, not Ingress or nginx.conf itself.

What you can do is use 'more_set_headers' to change your 'Server' value, as the following:

more_set_headers 'Server: BlaServer';

Change this in your nginx.tmpl and it will work as expected.
Probably there's also another way to do this, using something in ConfigMap as described here

Take a look to see if this is what you're looking for.

Seems like a good enough workaround and we shouldn't go another way, when nginx upstream is using it like that. Thanks for the workaround.

@stp-ip The ingress-nginx controller is built with the headers-more-nginx-module so you can use the more_clear_headers directive to completely remove the server output header:

more_clear_headers Server;
