nginx dynamic virtual hosts

Question

With nginx is there a method to setup mass dynamic virtual hosts similar to the way apache2 can be configured? I'm setting up an saas application each user will have their own subdomain and i'd like to use nginx over apache2.

Thanks

Code below should be how to configure

map $http_host $subdir {
hostnames;
default "default";
.foo.bar.com "foo";
.baz.bar.com "baz";
}

server {
root /path/to/$subdir;

}

Yes, setting up virtual hosts is definitely possible, please check Nginx documentation on server configuration directive and default config samples. The easiest way is to put server config sections in separate files under /etc/nginx/conf.d and to include them by a pattern, like include /etc/nginx/conf.d/*.conf; in the main nginx config file.
