I found a solution in this thread [here](https://meta.discourse.org/t/afatal-unable-to-access-https-github-com-samsaffron-pups-git-could-not-resolve-host-github-com/18611/5).

I looked up my DNS servers in resolv.conf, and put that in the configuration file for docker.  
I don’t know why docker doesn’t use the same dns as the rest of the system by default?  
What am I not understanding here?
