In this tutorial, we will explain how to install and set up systemd-nspawn on Ubuntu Server Latest. systemd-nspawn is a tool that allows administrators to create lightweight, secure containers that run specialized applications, isolated from the host system.
Before installing systemd-nspawn, we must first update the system to ensure that we have the latest packages and security updates:
sudo apt update
sudo apt upgrade
Once the system is up-to-date, we can proceed to install systemd-nspawn using the apt package manager:
sudo apt install systemd-container
This will install systemd-nspawn and all the required dependencies.
To verify that systemd-nspawn has been installed correctly, we can run the following command to check the version:
systemd-nspawn --version
To start a new container for a particular distribution, we need to create a directory to store the container, and then use the debootstrap tool to create the initial filesystem:
sudo mkdir /var/lib/container
sudo debootstrap ubuntu /var/lib/container
Once the container has been created, we can start it with the following command:
sudo systemd-nspawn -b -D /var/lib/container
This will start the container and drop us into a shell inside the container. We can use this shell to install packages or run applications.
In this tutorial, we have shown you how to install systemd-nspawn on Ubuntu Server Latest and how to create and start a container. With systemd-nspawn, you can easily create and manage secure, lightweight containers that can run specialized applications.
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!
