How to configure sub domain name IIS

Question

I work in a organization that has a certificate *.mycompany.com

I developed a ASP.NET CORE API and hosting my endpoints as windows servic e. How can i set the host name for my API like myapi.mycompany.com ? I can able to browse with servername:port.mycompany.com

There are already some sites configured on the same server which i deployed my application on port 7788

I gave a try and searching all articles in google and stack overflow but none of them understandable to fix that.

Answer 1

servername:port.mycompany.com is not a standard host name format. If you means that you can access the site via servername.mycompany.com:port. Then you should already have a local active domain and DNS forward lookup zone mycompany.com .

So please create an alias(CNAME) api for your host(A) servername.mycompany.com. Then its FQDN should be api.mycompany.com. Once you register DNS.

You should run ipconfig /flushdns and access the website via myapi.mycompany.com. If you don't want to expose port number. Please set your port number ASPNETCORE_URLS to 80.
