tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Get boot2docker working with nfs instead of vboxsf.

$ docker run --privileged --pid=host -it alpine:3.8 \
nsenter -t 1 -m -u -n -i sh

--rm : removes the container after it is stopped
-ti (or -t -i) : adds a tty and leaves the standard input opened
--privileged : grants additional permissions to the container, it allows the container to gain access to the devices of the host (/dev)
--pid=host : use the host's Process ID Namespace. Allows the container to use the process tree of the Docker host (the machine in which the Docker daemon is running)
