LXC ArchLinux Tutorial

TurnToJPG -->

Installation

Install lxc, bridge-utils, netctl from the official repository.

$ sudo pacman -S lxc bridge-utils netctl

For creating ArchLinux Container, install arch-install-scripts:

$ sudo pacman -S arch-install-scripts

Check Configurations:

$ lxc-checkconfig

Network Configuration

Since I use systemd for bridged network, so this step remains blank, the official Arch Wiki use netctl.

Creating Container Using Template

List all of the available templates:

$ ls /usr/share/lxc/templates 
lxc-alpine     lxc-centos    lxc-fedora        lxc-oracle  lxc-ubuntu-cloud
lxc-altlinux   lxc-cirros    lxc-gentoo        lxc-plamo
lxc-archlinux  lxc-debian    lxc-openmandriva  lxc-sshd
lxc-busybox    lxc-download  lxc-opensuse      lxc-ubuntu

Now using the template for creating the Linux Container:

$ sudo lxc-create -n Arch_Container -t /usr/share/lxc/templates/lxc-archlinux

If the container is created successfully, it will indicates that you could use it from now.

Start the Container

List the installed Containers:

$ sudo lxc-ls
Arch_Container  

Start the installed Container:

$ sudo lxc-start -n Arch_Container

The default username is root, and you will got a terminal window, now check the network configuration:

[root@Arch_Container ~]# ip link show dev eth0
5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff

Simply use dhcpcd we could get the ip address currently, and surely we can see this network configuration is OK now.
Enable the automatically dhcpcd at startup

$ dhcpcd
$ systemctl enable dhcpcd.service

Now reboot you will notice the ip address has been configurated automatically.

Create Other Distributions

First you should install yum and debootstrap from AUR repository.

$ yaourt -S yum
$ yaourt -S debootstrap

Fedora

Install Fedora or CentOS will failed, I don’t know why.

Debian

Install rxync first via:

pacman -S rsync

Some packages failed to download, so won’t install.

After installed rsync, install debian container via:

sudo lxc-create -n Debian_Container -t /usr/share/lxc/templates/lxc-debian

Start the container via:

 sudo lxc-start -n Debian_Container

The default username/password are root, In Debian network is not configured.
