Nginx. Just Nginx

I like to have a web server on my filer to serve files on my local network. You see, EVERYTHING supports http.

And I do not want access outside of my LAN.

So I went for a custom app and selected the standard nginx container.

The problem is user and group ids. Nginx needs to start up as root and then lowers to a non privleged user, which defaults to 101. Which is good practice. The problem is that TrueNAS has a user id for containers, 568, which is not the same as 101.

In the config template, it reads:

ARG UID=101
ARG GID=101

I would like to override these values to 568, but I can’t figure out how to do that with the GUI, despite them being called “ARG”s.

Thanks in advance, folks.
