[yocto] Running Docker

[Jakob Hasse]

Hello Bruce,

Thank you for the advice with the morty branch, this worked perfectly.

Now, however, docker is installed on my Yocto-system but I can't run it:

~# docker
-sh: /usr/bin/docker: No such file or directory

Is "docker" the client to control and run containers (e.g. "docker run 
hello-world")?
On my Ubuntu machine, this works, I installed docker and docker.io via 
apt, then I could run "docker run hello-world".

All the Best and many thanks in advance!
Jakob
