###share host tty device to containers , run X server inside docker , run startx and X11 3d application and desktop with nvidia-docker2
#screenshots
##firefox
this project is linkage with centos7-xfce4
- most article says run X server on host machine and mount X11 socket to container, but when you mount to many containers , host machine screen will becomes chaos
- I don't want to run X server on host machine, I want to run X server inside docker to keep my screen clean
- run 3d application (gaming , renderer )
- try using matlab in desktop environment
- my workmates think it's interesting
- I can't find a way how to make Xvfb using nvidia-driver and /etc/X11/xorg.conf
- I can't find a way to create a valid VT inside docker by using same command ( mknod -m 0620 /dev/tty99 c 4 0 )
- X11 server need /dev/tty0 for I/O
##what this plugin will make changes to your host machine
- it will automatically create a tty device on host machine, adrees is /opt/k8s-tty-device/tty99
- centos 7 host machine
- install X11 server on host, then install nvidia driver, (I guees must install x11 server before install nvidia driver,then nvidia will output /usr/lib64/xorg/modules/extensions) yum -y install xorg-x11-server-Xorg
- nvidia-docker2 installed
- privileged is required if run in container
- kubernetes 1.9 (warning kubernetes 1.10 is deferent,api has changed,1.10 code has been written will push later)
- an centos-xfce4 x11 desktop (will document this in later few days)
kubectl apply -f https://raw.githubusercontent.com/hakur/k8s-tty-device/master/k8s-tty-device.yml
-
master branch code version is kubernetes 1.9
-
xrog-glx is conflict with nvidia-glx (I hate this war)
-
if you want to install nvidia driver, you must diable nouveau kernel module try search blacklist nouveau on google or using very dangerious way ( modprobe -r nouveau )
-
nvidia driver seems no binary version, it's manual build with gcc and kmod (yum -y install gcc kmod pkgconfig),here is a simple command to build nvidia driver NVIDIA-Linux-x86_64-396.18.run -a -N --no-x-check --ui=none -s -q -no-nouveau-check --no-cc-version-check
