Contents
Setup variables
ARCH="i386" export DIST="precise" export NAME="ubuntu1204" export COUNTRY="de" TMPL="12.04-x86"
Prepare directory
apt-get -y install debootstrap debootstrap --arch $ARCH $DIST /var/lib/vz/template/$NAME http://$COUNTRY.archive.ubuntu.com/ubuntu chroot /var/lib/vz/template/$NAME
Steps in chroot
Configure locales:
locale-gen ru_RU.UTF-8 locale-gen en_US.UTF-8
Configure packages:
echo " deb http://$COUNTRY.archive.ubuntu.com/ubuntu $DIST main restricted universe multiverse deb http://$COUNTRY.archive.ubuntu.com/ubuntu $DIST-updates main restricted universe multiverse deb http://$COUNTRY.archive.ubuntu.com/ubuntu $DIST-security main restricted universe multiverse #eb http://$COUNTRY.archive.ubuntu.com/ubuntu $DIST-backports main restricted universe multiverse " > /etc/apt/sources.list : dpkg --remove ubuntu-minimal isc-dhcp-client isc-dhcp-common ntpdate resolvconf dpkg --purge ubuntu-minimal isc-dhcp-client isc-dhcp-common ntpdate resolvconf : apt-get update apt-get -y dist-upgrade
Configure mail system (consider 192.0.2.2 is IP of venet0 on HN, or put here your own SMTP relay if needed):
mkdir /etc/dma echo $NAME > /etc/mailname echo ' SMARTHOST 192.0.2.2 DBOUNCEPROG dbounce-simple-safecat MAILNAMEFILE /etc/mailname ' > /etc/dma/dma.conf : DEBIAN_FRONTEND=noninteractive apt-get -y install --no-install-recommends dma bsd-mailx safecat
Disable hardware-related configs:
sed -i.orig -e 's,^#!.*,#!/bin/true,' /etc/init.d/ondemand sed -i.orig -e 's,\(.* | \)\(sysctl .*\),\1 /bin/true \2,' /etc/init/procps.conf sed -i.orig -e 's,^console output,, ; s,^env INIT_VERBOSE,,' /etc/init/rc.conf sed -i.orig -e 's/^\$ModLoad imklog/## \$ModLoad imklog/g' /etc/rsyslog.conf sed -i.orig -e 's,^\([^#].*/dev/xconsole\),## \1,' /etc/rsyslog.d/50-default.conf : mkdir /root/etc_init_console_tty mv /etc/init/console* /etc/init/tty* /root/etc_init_console_tty
Cleanup and leave chroot:
find /var/cache/apt /var/lib/apt/lists -type f -delete apt-get clean exit
Create template archive
rm -f /var/lib/vz/template/cache/ubuntu-$TMPL.tar.gz && tar czf /var/lib/vz/template/cache/ubuntu-$TMPL.tar.gz --numeric-owner -C /var/lib/vz/template/$NAME .
How to create CT from template
ID=123 vzctl create $ID --ostemplate ubuntu-12.04-x86 --hostname … --name … --layout simfs vzctl set $ID --save --onboot yes --nameserver 192.0.2.2 --ipadd 192.0.2.$ID
Trusty notes
Debootstrap can miss Trusty profile (as in Debian Wheezy), so create it manually (and adopt DIST,NAME,TMPL):
... export DIST="trusty" export NAME="ubuntu1404" TMPL="14.04-x86" ... apt-get install -y debootstrap cd /usr/share/debootstrap/scripts && ln -s gutsy trusty debootstrap ...
