It's not clear to me why you're happy to generate an include file of
mappings in an external program, but not happy to generate an include
file of locations in an external program.
And if you have a large number of locations, you'll probably be happier
having no top-level regex locations.
But all that aside...
"map $var1 $var2" sets $var2 based on a string match of $var1.
You wish to match based on the first uri segment. So, do just that:
===
http {
map $first_segment $value {
default 127.0.0.1;
/abc 127.0.0.2;
/def 127.0.0.3;
}
server {
if ($uri ~* ^(/[^/]*) ) {
set $first_segment $1;
}
location / {
proxy_pass http://$value:8080/$uri ;
}
}
}
===
You may want to play with the proxy_pass line depending on exactly what
you want to do, but the above seems to work for me.
You can also add a $second_segment (or $part2) in the if{} block, if
you want a separate map for that.
Good luck with it,
