[wswv]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I tried to use the nginx as PHP runtime enviroument, I put the mybb in ngix docker directory "www", everything is fine, but when I tried to access dababase(used mariadb in a same docker network) following mybb installation process, it reports can't connect to database. there is no guidance or document how to configure the nginx docker to access database which outside the nginx docker. I'm not sure this is a right place to talk it here. but hope someone could help to support to solve it.

Expected Behavior

the PHP application below nginx docker could access docker database in a same docker network.

Nothing to do with nginx. You'll be telling the web app to either use to help container name or your servers host IP.
