Install LXC makina-states on ubuntu with upstart¶
Install lxc¶
Official doc: https://help.ubuntu.com/lts/serverguide/lxc.html
First install LXC
sudo apt-get install lxc bridge-utils
Prepare network connectivity¶
In makina-states, our images are known to use a network bridge called
lxcbr1.
They use the 10.5/16 network and 10.5.0.1 as the default gateway.
For this to work, you have plenty of solutions.
Network bridge¶
The first thing you ll have to do is to persist the network bridge. For this, on ubuntu, the simpliest thing is to inspire ourselves from the default lxc-net configuration and create the following configuration file
First, create as root this upstart job /etc/init/lxc-net-makina.conf & helpers:
for i in /etc/init/lxc-net-makina\
/usr/bin/magicbridge.sh /etc/reset-net-bridges;do
curl --silent \
"https://raw.githubusercontent.com/makinacorpus/makina-states/stable/files${i}" \
> "${i}"
done
chmod 644 /etc/init/lxc-net-makina
chmod 755 /usr/bin/magicbridge.sh /etc/reset-net-bridges
cp /usr/bin/magicbridge.sh /usr/bin/lxc-net-makina.sh
Don’t forget that you can read the upstart job but basically, it creates the bridge and then masquerade the outband traffic.
Then reload it with:
service lxc-net-makina restart
You will see you newly created bridge with:
# ip addr show dev lxcbr1

Activate kernel forwarding¶
Please follow Network route forwarding.
Install the image on ubuntu¶
You can now read and proceed with the following section, Install the base LXC container.
Note about firewalling on ubuntu¶
Last but not least, if you use a firewall, and we hope you do so, please refer to the firewalling section for further configuration. Please read Network firewalling and masquerating a makina-states LXC based image.
On ubuntu you may be using:
Install a new container¶
