Preface

I want to start out by saying I know there are at least 200 different SO posts on this exact issue, i've been over every one of them, to summarize for anyone else who stumbles upon this.

Issue

I have a NGINX container (Nginx01) that is acting as the front end to a php-fpm server. I want the NGINX server to respond to http://.com/wiki/ but strip the /wiki/ part of the URL before sending it to the backend server. I want to do this specifically to avoid making unnecessary changes to the mediawiki container although I am starting to feel that would be easier at this point...

Background Information

A single volume is shared between both containers hosting the website files. PHP files are hosted through the php-fpm container, all static files should be hosted through NGINX.

Key Tips I've Found

Be mindful of the slashes (/)

Remember that proxy pass + whats captured in the "(.*)" gets combined and thats your final URL. Ensure that you are not adding too many or too little slashes. (Ex1. http://localhost//subdir | Ex2; http://localhostsubdir)

rewrite ^/wiki/(.*)$ $1 break;

Ensure you have break in the command.

Ensure that the break command is located at the end of the rewrite command to ensure it stops processing.

rewrite ^/wiki/(.*)$ $1 break;
