It is too bad that you require vagrant (docker would be a better choice in my opinion). I do not want to install vagrant on my linux box. I want to run mongod directly on my machine.
I can do the assignments but I cannot run your validation scripts.
How hard would it be for you to have an option on your validation scripts to attach to ip 127.0.0.1 instead of requiring the vagrant ip address of 192.168.103.100 (or whatever it is)?
