Systemd-nspawn is a lightweight tool that creates and manages lightweight virtualized containers. As a containerization tool, it enables users to create a sandbox where applications or processes can run with their dependencies isolated from the host system. This tutorial will guide you through the installation of systemd-nspawn on OpenSUSE latest version.
Before installing any new package, it's advisable to update the existing package repositories. To do that, run the following command:
sudo zypper update
With the package repository updated, install the latest Systemd-nspawn package by running the command below.
sudo zypper install systemd-container
Once installed, verify that the package is up and running by checking its version.
systemd-nspawn --version
With the systemd-nspawn package installed, the next step will be creating the first container. To create a container, run the command:
sudo systemd-nspawn --directory=/var/lib/machines/<container-name> --machine=<container-name> --network-bridge=<bridge-interface-name>
Replace <container-name> with the desired name you wish to give for your new container. Also, replace <bridge-interface-name> with the name of your main network interface. In most cases, the interface name should be either br0 or virbr0. After executing the command above, wait for the container to be created.
After a successful container creation, start the container using the following command:
sudo systemd-nspawn -D /var/lib/machines/<container-name> --machine=<container-name>
Replace <container-name> with the name you created in step 3.
In this tutorial, we have demonstrated how to install systemd-nspawn on OpenSUSE and create a new container. At this point, the container is ready, and you can now start running applications in it. Systemd-nspawn is a lightweight and reliable tool for containerization, and it's easy to use, making it a worthy tool for your software deployment needs.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
