Set up and use an LXC container
Goal
Installing an LXC container. Images for the routers are available from the Jenkins website.
Prerequisites
NetModule Wireless Router with wireless connection
-
A license is required for the LXC container
Not available for legacy products NB1600, NB2700, NB3700, NB3710
1. Set up the LXC Contianer
Activate the LXC container on the router
In the second step the image of the LXC container in this case Debian.
The easiest way to do this is to install the whole thing over the Internet. However, the router requires a mobile connection to the Internet.
From a Jenkins server you get the current image for the container
* Jenkins Server Page / Link
The “armhf
” tab is important here
Here you can get a Debina image for buster, bullseye or bookworm
.
If you click on the circle with the green rakes, you will be taken to the software. What else is important is that the circle and rakes must be green.
The image is the “rootfs.tar.xz
” which is required. With a right click you can copy the link.
It would be structured like this:
https://jenkins.linuxcontainers.org/view/Images/job/image-debian/architecture=armhf,release=bookworm,variant=default/lastSuccessfulBuild/artifact/rootfs.tar.xz
When the “Apply” button is pressed, Debian will be installed.
2. Test LXC installation and set up further
Under the console you can first check whether the installation has been carried out.
USER
~ $ cd /mnt/storage0/lxc/guest0
/mnt/storage0/lxc/guest0 $ ls
bin dev home media opt root sbin sys usr
boot etc lib mnt proc run srv tmp var
/mnt/storage0/lxc/guest0 $
This file must be available under this directory structur
USER
~ $ lxc-info guest0
Name: guest0
State: RUNNING
PID: 20493
CPU use: 1.49 seconds
BlkIO use: 20.00 KiB
Memory use: 7.22 MiB
KMem use: 1.20 MiB
~ $
The LXC container is set up and already started.
Set up the LXC container further. A network interface is enabled here.
The container has now also been assigned an IP address.
USER
~ $ lxc-info guest0
Name: guest0
State: RUNNING
PID: 2255
IP: 192.168.1.149
CPU use: 1.57 seconds
BlkIO use: 4.00 KiB
Memory use: 6.29 MiB
KMem use: 1.18 MiB
Link: virt0
TX bytes: 2.28 KiB
RX bytes: 853 bytes
Total bytes: 3.11 KiB
~ $
Always assign a fixed IP address for the LXC container via the DHCP server.
Log in to the LXC container and test whether it can access the Internet.
USER
~ $ lxc-attach guest0

The container is installed and set up. Now you can set up further tools on the container.
