Nginx support specific wildcard server_name (regex) with fallback

Question

Im looking to do the following match:
*-server.*.* for example - dev-server.anydomain.anytld

in the same file, another server:
*-cloud.*.* for example - dev-cloud.anydomain.anytld

fallback - in the same file - if non of the above were NOT matched:
*.*.* for example - dev.anydomain.anytld or somethingelse.anydomain.anytld

This is what I have now which is not working:

server {
 listen       80;
 server_name  ~(server)*$;
}

server {
 listen       80;
 server_name  ~(cloud)*$;
}

server {
 listen       80;
 server_name  *.*.*$;
}

you can use this tool to handle it https://nginx.viraptor.info/

Thanks

Your regular expressions are not valid.

To match *-server.*.* use:

server_name ~-server\.[^.]+\.[^.]+$;

To match *-cloud.*.* use:

server_name ~-cloud\.[^.]+\.[^.]+$;

You do not need a server_name statement to match anything else, just use:

listen 80 default_server;

Also, Nginx has a wildcard syntax and a regular expression syntax for server_name directives. They have different evaluation rules. The above examples use regular expressions, which are evaluated in order until a matching expression is found. See this document for details.

Hi, the first config answers to both domains: demo-server.domain.com and demo.domain.com

It doesn't match the regex so it must be using that server block as the default_server. Have you defined a default_server?

yes. this server_name ~-server\.[^.]+\.[^.]+$; and default_server. it always goes to the server...
