I am building a cluster of servers in which new virtual machines will spin up as resources are needed. Is it possible in the apache config file to use a variable that will detect the servers ip address and assign it to a virtualhost instead of me having to specify it manually?

<VirtualHost 192.168.1.35:8080>
    ServerName whatever.com
    ServerAlias whatever.com
</VirtualHost>

Chef/Ansible/Puppet/Salt can do this exactly how you want using a configuration template.

Since I've used puppet the most, their documentation shows how to do this.
