Description
When using an include file with the map directive, it would be ideal if nginx automatically reloaded its configuration when the include file is modified.
Use-case: currently I use the map functionality to rewrite a 'current' URL for downloads to the latest version as produced by buildbot. As nginx is running in a docker container, there isn't any way to reload the nginx configuration without root privileges (at least that I'm aware of).
E.g. buildbot runs a script to generate currentImages.map.nginx:
/nightly-images/x86_64/current-anyboot /nightly-images/x86_64/haiku-nightly-hrev51366-x86_64-anyboot.zip;
If instead, I use a symlink in /nightly-images/x86_64, ln -s haiku-nightly-hrev51366-x86_64-anyboot.zip current-anyboot, then when downloading the file using the current link, the downloaded file has the name of the symlink, rather than the target.
My configuration is along the lines of:
http {
map $uri $new {
include /haiku-files/nightly-images/currentImages.map.nginx;
}
server {
if ($new) {
return 302 $new;
}
}
}
With Apache2 and RewriteMap, it automatically reloads the map configuration when the include file is modified. I can't see any way to achieve the same with nginx, which will hamper moving away from Apache2.
