Using Environment Variables in AEMaaCS

Hi AEM Community,

I have the below code configured in my dispatcher_vhost.conf - 

# Allow ingressroute checks through on /systemready (regardless of dispatcher filters)
<Location "/systemready">
   ProxyPass http://${AEM_HOST}:${AEM_PORT}/systemready
   RewriteEngine Off
</Location>

# Allow access to CRXDE on dev environment
<IfDefine ENVIRONMENT_DEV>
    <LocationMatch "/crx/(de|server)/">
        ProxyPassMatch http://${AEM_HOST}:${AEM_PORT}
        RewriteEngine Off
    </LocationMatch>
</IfDefine>

We have not defined any Environment Variables for AEM_HOST and AEM_PORT as referenced above.

In AEMaaCS the CRXDE access is disabled by default. Hence, the above configuration doesn't make sense to include in dispatcher_vhost.conf.

Query 1 - Do we need to configure these parameters  ? I checked the WKND codebase but was unable to find these parameters defined in the /conf.d/variables folder.

Query 2 - In AEMaaCS should these parameter be configured ? If yes, then how should these parameters be defined ?

We usually have only Program ID and Environment ID.
