 A list of vhost definitions (server blocks) for Nginx virtual hosts. Each entry will create a separate config file named by `server_name`. If left empty, you will need to supply your own virtual host configuration. See the commented example in `defaults/main.yml` for available server options. If you have a large number of customizations required for your server definition(s), you're likely better off managing the vhost configuration file yourself, leaving this variable set to `[]`.
