How to get dev.*.domain.com to work on nginx

Question

I'm trying to make nginx accept websites in this format: dev.*.domain.com. I've read the docs and I understand that I have to use a regex for that.

A wildcard name may contain an asterisk only on the name's start or end, and only on a dot border. The names “www..example.org” and “w.example.org” are invalid. However, these names can be specified using regular expressions, for example, “~^www..+.example.org$” and “~^w..example.org$”. An asterisk can match several name parts. The name “.example.org” matches not only www.example.org but www.sub.example.org as well.

So I have:

server { listen 80; server_name ~^dev\..+\.domain\.com\.br$ dev.domain.com.br; access_log /var/log/nginx/dev.domain.com.br.access.log; error_log /var/log/nginx/dev.domain.com.br.error.log; location / { proxy_pass http://127.0.0.1:68319/; include /etc/nginx/proxy.conf; } location /media/ { alias /my/folder/to/media/; expires 15d; } location /favicon.ico { alias /my/folder/to/favicon.ico; expires 15d; } } 

Somehow it ends being catched by this rule (which is the last one):

server { listen 80; server_name *.domain.com.br domain.com.br; access_log /var/log/nginx/domain.com.br.access.log; error_log /var/log/nginx/domain.com.br.error.log; location / { proxy_pass http://127.0.0.1:8080/; include /etc/nginx/proxy.conf; } location /media/ { alias /my/path/to/media/; expires 15d; } location /favicon.ico { alias /my/path/to/favicon.ico; expires 15d; } } 

Any ideas? Many thanks in advance.

PS: I think it's being catched by *.domain.com because of the order nginx tests for matches. Is there anyway I can rewrite *.domain.com to only test for 1 subdomain level? i.e. test.domain.com matches *.domain.com, but sub.test.domain.com doesn't.

*.domain.com is just a simple suffix match, there's no way to limit it to a single subdomain level. To accomplish what you want, you'll have to convert your suffix check to also be a regex:

server { server_name ~^dev\..+\.domain\.com\.br$ dev.domain.com.br; ... } server { server_name ~^[^.]+\.domain\.com\.br$ domain.com.br; ... } 

with both checks being regex, the order of the server blocks matters.
