To create a most basic Debian Jessie container, you can follow these steps:
mkdir jessie cd jessie mkdir rootfs cd rootfs/ debootstrap jessie . http://ftp.de.debian.org/debian/ chroot . passwd
You should not forget to set the root password as it is good to have a known value later.
Now that we are within the container, we can configure the most basic settings that we will need for all containers:
tasksel --task-packages standard | xargs apt-get install -y dpkg-reconfigure locales
Here I am usually generating
de_DE.ISO-8859-1 de_DE.UTF-8 de_DE.ISO-8859-15@euro en_US.ISO-8859-1 en_US.ISO-8859-15 en_US.UTF-8
and set the default to en_US.UTF-8 .
To get the full repository contents, you should change your repository sources to look as below:
deb http://ftp.de.debian.org/debian jessie main contrib non-free deb http://ftp.de.debian.org/debian-security jessie/updates main contrib non-free
and then do an
aptitude update .
You should also install an SSH server by entering
aptitude install openssh-server
Enable root logins via SSH by changing one line in its configuration:
Unfortunately systemd is not yet working easily with LXC, so it should be replaced by the old sysvinit:
aptitude install sysvinit-core dpkg -P systemd
Edit initial DNS resolver configuration so it looks like this:
search yourdomain.com nameserver ip.of.your.namserver
Then also configure the main network interface configuration:
auto eth0 iface eth0 inet static address 192.168.168.100 netmask 255.255.255.255 gateway 192.168.168.1 iface eth0 inet6 static address 2001:aaaa:bbbb:0168::2 netmask 64 gateway 2001:aaaa:bbbb:0168::1
Replace /etc/inittab with the following short version which is enough for a container:
id:2:initdefault: si::sysinit:/etc/init.d/rcS ~~:S:wait:/sbin/sulogin l0:0:wait:/etc/init.d/rc 0 l1:1:wait:/etc/init.d/rc 1 l2:2:wait:/etc/init.d/rc 2 l3:3:wait:/etc/init.d/rc 3 l4:4:wait:/etc/init.d/rc 4 l5:5:wait:/etc/init.d/rc 5 l6:6:wait:/etc/init.d/rc 6 z6:6:respawn:/sbin/sulogin 1:2345:respawn:/sbin/getty --noclear 38400 console p0::powerfail:/sbin/init 0 p6::ctrlaltdel:/sbin/init 6
Should the network not come up automatically, you can set the IP address in the config file of the container:
After a first start, you should also configure the mail server so it can send all system mail to your main mail server:
and answer all the questions.
Shut the machine down again, cleanup all the log files and make a copy which you can then use as your template for further containers.
