- ====== Set up and use an LXC container  ====== +====== 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 
 +  * NetModule Software [[https://share.netmodule.com/public/system-software/4.8/4.8.0.103/|4.8.0.103]] or newer 
 +  * A license is required for the LXC container 
 +  * Not available for legacy products NB1600, NB2700, NB3700, NB3710 
 + 
 +===== - Set up the LXC Contianer ===== 
 + 
 +Activate the LXC container on the router  
 + 
 +{{:pictures:lxc_aktiv.png?800|}} 
 + 
 +In the second step the image of the LXC container in this case Debian. 
 + 
 +{{:pictures:lxc_install.png?800|}} 
 + 
 +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 image-debian / [[https://jenkins.linuxcontainers.org/view/Images/job/image-debian/|Link]] 
 + 
 +The "''armhf''" tab is important here 
 + 
 +Here you can get a Debina image for ''buster, bullseye or bookworm''. 
 + 
 +{{:pictures:lxc_jenkins.png?800|}} 
 + 
 +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. 
 + 
 +{{:pictures:lxc_link.png?800|}} 
 + 
 +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. 
 + 
 +===== Other LXC container images ===== 
 + 
 +Two more LXC images are currently being offered on the Jenkins server.  
 +You can use an Alpine or Ubuntu image for the container. 
 + 
 +* Jenkins Server Page image-alpine / [[https://jenkins.linuxcontainers.org/view/Images/job/image-alpine/|Link]] 
 + 
 +* Jenkins Server Page image-ubuntu / [[https://jenkins.linuxcontainers.org/view/Images/job/image-ubuntu/|Link]] 
 + 
 + 
 +===== - Test LXC installation and set up further ===== 
 + 
 +Under the console you can first check whether the installation has been carried out.

 + 
 +Set up the LXC container further. A network interface is enabled here.  
 + 
 +{{:pictures:lxc_netzwerk.png?800|}} 
 + 
 +The container has now also been assigned an IP address.

 + 
 +Always assign a fixed IP address for the LXC container via the DHCP server. 
 + 
 +{{:pictures:lxc_ip_adresse.png?800|}} 
 + 
 +Log in to the LXC container and test whether it can access the Internet.

 +<konsole> 
 +~ $ lxc-attach guest0

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