Share your X11 socket/cookie, and now everything you input (keyboard/mouse,etc.) is readable by a so called "contained" application; this is not a secure solution, but more of a comfort solution, and it should be used as such. On a side note, I've been doing this with chroot/debootstrap for years, but lxc/docker provide a nice "engineered" solution.
