Root URL

[Andrius]

Is it possible to add client root URL with something like ${IP}:8080?

If I add to root url: ${authBaseUrl} and Home url: /dcm4chee-arc/ui2/

The whole URL looks like this: 

http://10.0.2.15:8082/dcm4chee-arc/ui2/ 

The problem that port 8082 is keycloak's port, I need to to use dcm4chee port (8080) and URL must look like this"

http://10.0.2.15:8080/dcm4chee-arc/ui2/ 

I cannot simply put IP, because it will vary. It has to be automatic. Is there something like ${IP}? Or any other solution?
