docker with path for reverse proxy https://example.com/somepath/

[chrismaster]

Is it possible for docker to set a path with docker for a reverse proxy?
Didn't find any environment variables, or env.file to set https://example.com/PATH/

What works is mount index.html Volume=%h/tmailDATA/index.html:/usr/share/nginx/html/index.html:Z (for podman with quadlet)
and edit <base href="/"> to eg <base href="/tmail/">
Maybe not an elegant solution, but it works.
Some environment variables would be a great addition. e.g. path, port, ...
for changing port i had to mount nginx.conf
Volume=%h/tmailDATA/nginx.conf:/etc/nginx/nginx.conf:Z
and change listen 80; to eg listen 3000;
Thx for this cool project....
