Using Upstreams in DB less mode

Kong Version : 2.0
DB Less mode.
How can we use upstreams in DB less mode. I did not find any reference in the DOCs.

This is not explicltly documented but kong config init should generate a file which can help you understand how the file is designed.

Here is an example: https://github.com/hbagdi/deck/blob/741b215ebc3954151e362bbad7594b7c43e62d70/kong.yaml#L32
