Is your feature request related to a problem? Please describe.
I have deployed a NPM in docker to proxy the web services in other containers. Most of the backend services are work well entil I added a Guacamole, which was written in java with servlet.
The homepage of guacamole was http://guacamole.host/guacamole, whose suffix guacamole was unavoidable when using offical images. When I added a proxy host in NPM with domain rdp.example.com, I found I need to access the guacamole with http://rdp.example.com/guacamole and http://rdp.example.com displayed as a 404 page.
Although I can remove the suffix by repacking guacamole's image, I will loss the automatic update feature provided by watchtower which can update docker image from official repository.
Describe the solution you'd like
The nginx supports add a path on proxy_pass:
location / {
proxy_pass ${proto}://${server}:${port}/${path}
... other configurations.
}
I'll appreciate if NPM can add a text box and support to append path suffix for proxy_pass.
Describe alternatives you've considered
I have tried to add some advanced custom configuration, but the location / is always overwrite by NPM and lead my custom configuration into a crash.
