I have successfully installed StarlingX, I need some help to proceed further.

• We have controller-0 which will act as a master. Is it possible to add worker node inside controller-0? Since we can't deploy the application on the master node(controller-0).
• I have to create an application which has to be deployed inside StarlingX. Is there any other way to do it?
• Since sanity test is failing, Is there any other way in which I can check if StarlingX is working properly?
