Setup lxd cluster for megatest
I setup 3 container "boxes" - pablo, ruby, ash
- shared disk space at /lxd-shared
- picked pablo to serve vnc
- put containers on home network to make things easy
install lxd - loosely followed this
put containers on home LAN- followed this procedure
host# lxc 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
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 pablo sharedtmp disk path=/lxd-shared source=/lxd-shared
Setup containers
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
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
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 [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic &
mtuser% echo "vncserver -geometry 1366x746 -depth 24" > ./vncgo mtuser% chmod +x ./vncgo; ./vncgo
fix consternating issue breaking tab completion working in any term:
- edit ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml
find the line
<property name="<Super>Tab" type="string" value="switch_window_key"/>
and change it to
<property name="<Super>Tab" type="empty"/>
restart vnc (
vncserver -stop :1 ; ./vncgo
)
start a vnc session (so iup works)
from home network, use vnc client to connect to container:1
setup shop in /lxd-share, eg:
% cd /lxd-share % fossil clone http://kiatoa.com/fossils/megatest megatest.fossil .....
