All in one BigFix Server

Hi,

I am pretty new to BigFix, my question might be a basic one.

I wanted to know if I can have One server which can act as my all in one server. I want to use this machine for BigFix, Relay, BareMetal. Is it possible to do that as I have installed MDT Bundle Creators and Windows Media but when I try to click on the server my Create MDT Bundle stays greyed out link below:

Also, I have uploaded CentOS7 Image and created a Profile but when I try to send I get below error:
There are no valid servers to send profiles to, check server status in the server management dashboard.

When I check on Server Management, I do not see any machine listed there.

When I click on install I get below error:

No Applicable Computers

There are no applicable machines. Machines must be relays, encrypted using the Enable Encryption for Clients fixlet, and the same architecture as the uploaded installers.

Need help and your expert advise on this.

Thanks,
