Install Docker on course VM

[pablomguevara]

Docker is not pre installed on course VM.

If you try to install Docker on course VM (Ubuntu 14.04), you can follow these instructions:

https://docs.docker.com/installation/ubuntulinux/

But this updates the kernel, and after words the shared folders no longer work; to fix, you need to reinstall guest additions, and do:

vagrant up
vagrant reload

This should be verified.

Suggestions for improvements:

• pre Install docker on course VM so everybody is running on the same kernel and people can play with docker on the VM
• ship the VM as is, but provide working instructions to install docker (not the prefered choice if you ask me)

Can you include the steps needed for "reinstall guest additions"? I think the best thing for us to do is to simply ship a VM with Docker in the future.

Yes, I'll do that.
