Answer 1

1. Running Docker on OS X : running the following eval has worked for me.

eval "$(docker-machine env default)"

2 If you do not want to run this eval statement on every terminal session then you can add this to your bash_profile:

#Docker
eval "$(docker-machine env default)"

3. Please make sure to restart the terminal session or run source on bash_profile for the changes to take effect.
