- put containers on home network to make things easy
## install lxd - loosely followed [this](https://stgraber.org/2015/04/21/lxd-getting-started/)<a id="orgheadline2"></a>
## put containers on home LAN- followed [this](https://insights.ubuntu.com/2015/11/10/converting-eth0-to-br0-and-getting-all-your-lxc-or-lxd-onto-your-lan/) procedure<a id="orgheadline3"></a>
host# mkdir /lxd-shared
host# chown 100000:100000 /lxd-shared
host# chmod 777 /lxd-shared
host# xc remote add images images.linuxcontainers.org
host# lxc launch images:ubuntu/xenial/amd64 ruby
host# lxc launch images:ubuntu/xenial/amd64 pablo
host# lxc launch images:ubuntu/xenial/amd64 ash
## setup shared space across containers, mounted from host fs<a id="orgheadline4"></a>
mkdir /lxd-shared
- my root disk is bigly
chmod 777 /lxd-shared
host# lxc config device add ruby sharedtmp disk path=/lxd-shared source=/lxd-shared
host# lxc config device add ash sharedtmp disk path=/lxd-shared source=/lxd-shared
host# lxc config device add ruby sharedtmp disk path=/lxd-shared source=/lxd-shared
host# lxc config device add ash sharedtmp disk path=/lxd-shared source=/lxd-shared
host# lxc config device add pablo sharedtmp disk path=/lxd-shared source=/lxd-shared
## Setup containers<a id="orgheadline5"></a>
- Foreach container :
host# lxc exec container /bin/bash
container# apt update
container# apt upgrade
container# apt-get install -y openssh-server htop ncurses-term fossil make
container# service ssh start
container# addgroup megatest
container# adduser --ingroup megatest mtuser
container# apt-get install -y libreadline-dev
container# apt-get install -y libwebkitgtk-dev libfreetype6-dev libx11-dev libxpm-dev libxmu-dev libxft-dev libgtk2.0-dev \
container# libgl1-mesa-dev libglu1-mesa-dev libpangox-1.0-dev \
container# bison libwebkitgtk-3.0-dev
container# apt-get install -y libmotif-common
container# apt-get install -y uuid-dev
## setup ssh host keys across mtuser<a id="orgheadline6"></a>
host# lxc exec container1 /bin/bash
container1# su - mtuser
% ssh-keygen
- leave password blank, take all defaults
% cat .ssh/id\_rsa.pub > .ssh/authorized\_keys
% chmod go= .ssh/authorized\_keys
% tar czvf /lxd-shared/mtuser-ssh.tgz .ssh
% ssh container2 tar xzvf /lxd-shared/mtuser-ssh.tgz
% ssh container3 tar xzvf /lxd-shared/mtuser-ssh.tgz
- ssh between all pairs to initialize host keys. should be passwordless now.
## pick a container and setup X / vnc<a id="orgheadline7"></a>
container# apt-install vnc4server xfce4
container# su -c mtuser
% vncpasswd
put following in .vnc/xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION\_MANAGER
# exec /etc/X11/xinit/xinitrc
#[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
#[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
#xsetroot -solid grey
#vncconfig -iconic &
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
#!/bin/sh
unset SESSION\_MANAGER
unset DBUS\_SESSION\_BUS\_ADDRESS
startxfce4 &
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
