Linux Containers (LXC) is a powerful lightweight virtualization technology that can run multiple isolated Linux systems (containers) on a single host. It allows you to deploy applications and services in a more efficient, flexible, and secure environment without the overhead of traditional virtual machines.
Fedora CoreOS is a next-generation container-oriented operating system designed for running containerized workloads at scale. In this tutorial, we will show you how to install LXC on Fedora CoreOS latest.
Before we start, make sure you have the following:
The LXC package is available in the official Fedora CoreOS repositories. To install it, connect to your Fedora CoreOS instance and run the following command as a sudo user:
$ sudo dnf install lxc
This command will download and install the LXC package and all its dependencies.
By default, LXC stores container images and data in the /var/lib/lxc directory. To configure a different storage location, you need to edit the LXC storage configuration file:
$ sudo nano /etc/lxc/lxc.conf
In this file, you can set various parameters, but for now, we need to modify the lxc.lxcpath parameter. Uncomment the line by removing the # character at the beginning of the line, and change the storage path to your desired location. Here is an example:
lxc.lxcpath = /mnt/lxc
Save the changes and exit the editor.
Before you can start using LXC on Fedora CoreOS, you need to start the LXC service:
$ sudo systemctl start lxc.service
You can also enable the service to start automatically at boot time:
$ sudo systemctl enable lxc.service
To test that LXC is working correctly, you can create a new container using a pre-built template:
$ sudo lxc-create -t download -n fedora-container
This command will download a Fedora container image and create a new container named fedora-container. Once the command finishes, you can start the container:
$ sudo lxc-start -n fedora-container
You can access the container console by running:
$ sudo lxc-console -n fedora-container
To stop the container, run:
$ sudo lxc-stop -n fedora-container
In this tutorial, we have shown you how to install LXC on Fedora CoreOS latest. With LXC, you can create and manage lightweight virtual environments on your Fedora CoreOS instance, using minimal resources and without sacrificing performance. We hope you find this tutorial helpful, thank you for reading.
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!
