How can we configure subdomain in spring-boot?

How can we configure subdomain in spring-boot? We use the embedded Tomcat server. Any idea of how to go ahead with it. I was told that we cannot use ngnix in spring-boot embedded tomcat.

Solution

  • Subdomain is on the DNS level and has nothing to do with Spring Boot.

    You have to have a web server in front of the Spring Boot app like nginx or Apache that will act as a reverse proxy.

    With nginx this could look like this:

    server {
  listen 80 default_server;
  server_name subdomain.domain.com;
  location / {
      proxy_pass http://localhost:8080;
      proxy_set_header Host      $host;
      proxy_set_header X-Real-IP $remote_addr;
  }
}

    Edit

    If you only want to pass to one page:

    proxy_pass http://localhost:8080/the_one_and_only_page.html;
