In this tutorial, we will set up a user level systemd unit for an unprivileged user. There are times when it's helpful to launch a user-level https://www.freedesktop.org/software/systemd/man/systemd.unit.html[systemd unit] without having to log in. For example, you may wish to launch a container that provides a network service or run an HPC job. Below is an example .fcc file that can be converted to ignition for the purpose of launching a systemd service for the user "sleeper".For this setup, we will add the following to a Butane config:

Launching a user-level systemd unit on boot
 
Complete all the steps described in the xref:tutorial-setup.adoc[initial setup page] before starting this tutorial. Make sure you have create file `ssh-key.pub` following the instructions provided in the https://docs.fedoraproject.org/en-US/fedora-coreos/tutorial-setup/#_ssh_public_key[prerequisites] for the tutorial. We will use this key in the Butane configuration file that we are about to write.

Hay veces que es útil lanzar un https://www.freedesktop.org/software/systemd/man/systemd.unit.html[systemd unit] a nivel de usuario sin tener que acceder. Por ejemplo, desea lanzar un contenedor que suministra un servicio de red o ejecutar un trabajo HPC. Lo de abajo es un ejemplo de un fichero .fcc que se puede convertir a ignición con el propósito de lanzar un servicio systemd para el usuario "sleeper".
A user level systemd unit: `/home/sleeper/.config/systemd/user/linger-example.service`.
 
Enable it as a user level systemd service.
 
Setting up the systemd unit
 
In this example, we will launch a systemd service for the user `sleeper`. First, let's create a user:
 
variant: fcos
version: {butane-latest-stable-spec}
passwd:
users:
- name: sleeper
 
This will also create the home directory for the `sleeper` user. Then we can add the systemd unit:
 
variant: fcos
version: {butane-latest-stable-spec}
storage:
files:
- path: /home/sleeper/.config/systemd/user/linger-example.service
mode: 0644
contents:
inline: |
[Unit]
Description=A systemd user unit demo
[Service]
ExecStart=/usr/bin/sleep infinity
user:
name: sleeper
group:
name: sleeper
 
System services can be directly enabled in Butane configs but user level services have to be manually enabled for now:
 
variant: fcos
version: {butane-latest-stable-spec}
storage:
directories:
- path: /home/sleeper/.config/systemd/user/default.target.wants
mode: 0755
user:
name: sleeper
group:
name: sleeper
links:
- path: /home/sleeper/.config/systemd/user/default.target.wants/linger-example.service
user:
name: sleeper
group:
name: sleeper
target: /home/sleeper/.config/systemd/user/linger-example.service
hard: false
 
We set up lingering for the systemd user level instance so that it gets started directly on boot and stays running:
 
variant: fcos
version: {butane-latest-stable-spec}
storage:
files:
- path: /var/lib/systemd/linger/sleeper
mode: 0644
 
As the following directories do not exist yet, we will have to create them to tell Ignition to set the right ownership and permissions:
 
variant: fcos
version: {butane-latest-stable-spec}
storage:
directories:
- path: /home/sleeper/.config
mode: 0755
user:
name: sleeper
group:
name: sleeper
- path: /home/sleeper/.config/systemd
mode: 0755
user:
name: sleeper
group:
name: sleeper
- path: /home/sleeper/.config/systemd/user
mode: 0755
user:
name: sleeper
group:
name: sleeper
- path: /home/sleeper/.config/systemd/user/default.target.wants
mode: 0755
user:
name: sleeper
group:
name: sleeper
