[BUG] Unable to add "resolver" directive to Reverse proxy settings

[gutleib]

What happened?

I have installed Bunkerweb 1.6.0 (BTW -- thank you for great software!) and is testing it right now.
We are running a Nomad+Consul on several hosts for fault-tolerance. Service discovery uses Consul dynamical DNS resolving for routing traffic.
To do so, we need to use "resolver" directive of Nginx. As I understand, additional settings go to " Reverse proxy includes" field in Reverse proxy plugin page in UI. But when I enter something like `"resolver 10.5.0.1 valid=5s;", field blocks saving and applying.
Now maybe I'm using it wrong, but this seems to be intuitive place for it.

How to reproduce?

Try to input a line of Nginx config in "Reverse proxy includes" field on "Reverse proxy － v1.0" page of Bunkerweb 1.6.0

Hi @gutleib,

Thank you for opening this issue! The REVERSE_PROXY_INCLUDES directive is specifically designed for configurations that require the include prefix. For your use case, you'll need to create a custom configuration to achieve the desired setup.

https://docs.bunkerweb.io/testing/advanced/#custom-configurations

Thank you!
Will "/configs/global/http" section be appended to every service, of am I understanding documentation wrong?

I'm trying to add resolver 10.5.0.1 valid=5s; to it, but getting "config wrong, rolling back". Or is such option make all gui-configuring impossible, and "custom config" needs to be complete nginx config altogether?

Hi @gutleib, that's because we already have a setting that sets it: DNS_RESOLVERS. Also when you're having a configuration issue BunkerWeb logs should tell you what happened when the test is done (we test the config before executing a reload so your server is still up and running).
