I have nginx setup to create the upstream on the fly.
if ($request_uri ~* “^/(.*)/resource”)
set $user $1;
so here if the url is
nginx will send that to nginx.resource.domain.com:7600
I have setup bind on the same machine (with zone files) and have the
resolver set to 127.0.0.1;
Local digs (dig @127.0.0.1 nginx.resource.domain.com +short) take ms.
When I include the upstream with the ip, the passing is instant, when I
don’t have the upstream which forces the use of the resolver it take
over 30 seconds.
Has anyone seen this behavior ? I didn’t find much info on the resolver
Also how do I tell the resolver to use the systems resolver method ?
So I want nginx to use whatever the OS uses (dns entries in resolv.conf
or hardcoded ips in /etc/hosts.
