Prerequisites for the tutorials
The following tutorials are focused on helping you get started with Fedora CoreOS by learning how to automatically configure (or provision) an instance on first boot. Each tutorial has its roots in the previous one thus it is recommended to follow them sequentially.
If you don't know what Fedora CoreOS is, you can refer to the xref:faq.adoc[FAQ] for more information.
If you need any help or need to ask any questions while going through those tutorials, please join the link:https://chat.fedoraproject.org/#/room/#fedora:fedoraproject.org[Matrix room], or join our https://discussion.fedoraproject.org/tag/coreos[discussion board]. If you find any issue in the tutorial, please report them in the https://github.com/coreos/fedora-coreos-docs/issues[fedora-coreos-docs issue tracker].
You should start with the setup instructions from this page as they must be completed first to be able to follow the tutorials.
xref:tutorial-autologin.adoc[Enabling autologin and custom hostname]
In this tutorial, you will write your first Ignition config and start a Fedora CoreOS instance with it.
xref:tutorial-services.adoc[Starting a service on first boot]
In this tutorial, you will learn how to start a custom script via a systemd unit on the first boot of a Fedora CoreOS instance.
xref:tutorial-containers.adoc[SSH access and starting containers]
In this tutorial, you will learn how to start a container at first boot with podman.
xref:tutorial-user-systemd-unit-on-boot.adoc[Launching a user-level systemd unit on boot]
There are times when it’s helpful to launch a user-level systemd unit without having to log in. This tutorial demonstrates creating a user-level systemd unit that launches on boot.
xref:tutorial-updates.adoc[Testing Fedora CoreOS updates]
In this tutorial, you will learn how automatic updates are handled in Fedora CoreOS and how to rollback in case of failures.
Virtualization with `libvirt`
These tutorials are written targeting a Linux environment with a working `libvirt` setup and hardware virtualization support via `KVM`. There is, however, nothing specific to the `libvirt` environment in those tutorials and you can thus try the same configurations on any platform where you have console access (or you can skip to the SSH access tutorial to get remote access).
For instructions to set up `libvirt` and `KVM` you may refer to the https://docs.fedoraproject.org/en-US/quick-docs/getting-started-with-virtualization/[Getting started with virtualization] guide from Fedora. Although this setup guide is focused on Fedora, the tutorials should work on any distribution with `libvirt` installed and running.
Local working directory
To keep all configuration files and Fedora CoreOS images in the same place, we will create a new directory to work from:
mkdir ~/coreos
cd ~/coreos
SSH public key
Some of the tutorials add an SSH public key to the instances to allow for SSH access as opposed to serial console access. Please place a public key in your current working directory under the filename `ssh-key.pub`. For example, for a RSA keypair the default location would be in `~/.ssh/id_rsa.pub`:
cp ~/.ssh/id_rsa.pub ssh-key.pub
