- Install dependencies
apt-get install lxc debootstrap libpasswd-unix-perl libfile-slurp-perl \
libmoose-perl libpath-class-perl libconfig-inifiles-perl
- Set up networking
Your containers need a way to talk to the interweb. One way is a bridge.
A bridge is basically like a switch. You can plug your eth0 into it, and
also each container. Then they can all talk to each other and the outside
world.
Put something like this in /etc/network/interfaces:
auto lo
iface lo inet loopback
iface eth0 inet manual
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
post-up /usr/sbin/brctl setfd br0 0
If you have a static lease, configure br0 with that information instead of the dhcp line::
iface br0 inet static
address [your ip]
netmask [your netmask]
broadcast [your broadcast]
gateway [your gateway]
bridge_ports eth0
bridge_stp off
post-up /usr/sbin/brctl setfd br0 0
- Put info about networking setup in a file for later use
When containers are created, we need to tell them how to access the network.
Put this in /etc/lxc/lxc.conf:
lxc.network.type=veth
lxc.network.link=br0
lxc.network.flags=up
- You're ready!
# Summary of commands
lxc --help
# Create a container called 'test'
lxc test create
# Start the container
lxc test start
# Enter it
lxc test enter
# Stop the container
lxc test stop
# Destroy it (you'll be asked to confirm)
lxc test destroy
- Starting containers automatically on boot
On ubuntu, install the upstart jobs:
cp upstart/lxc-* /etc/init
And when you create your containers, use -a to flag them as ones that should be automatically started on boot.
If you have a container you already made that you want to start on boot:
touch /var/lib/lxc/[name]/autostart
