New to docker.
Installed docker from software management tool in
When I run
docker run hello-world I receive:
FATA Error response from daemon: Cannot start container a6bcc1ede2c38cb6b020cf5ab35ebd51b64535af57fa44f5966c37bdf89c8781:  System error: mountpoint for devices not found
When I look at the service logs (
/var/log/upstart/docker.log) I see:
ERRO Couldn't run auplink before unmount: exec: "auplink": executable file not found in $PATH ERRO Couldn't run auplink before unmount: exec: "auplink": executable file not found in $PATH

sudo apt-get install aufs-tools, restarted docker service. I no longer see the following error:
ERRO Couldn't run auplink before unmount: exec: "auplink": executable file not found in $PATH
However, in the logs I see that when docker is starting it is warning me about memory mount point:
INFO -job init_networkdriver() = OK (0) /var/run/docker.sock is up WARN mountpoint for memory not found INFO Loading containers: start.
I have a feeling it has to do with cgroup...but i don't know anything about that technology (yet)...
