quadit

A gitops tool to deploy systemd managed containers on linux. A.K.A quadlets.

Introduction

quadit is focused on managing quadlets and running containers in rootless mode using a gitops model.

The quadit' core usecase is a remote edge scenario enforcing a pure pull model that ensures no inbound access to the device.

It is written in rust to minimise the overall footprint and improve the power consumption of running a gitops service on low resourced systems.

For more detail on quadlet see this article.

features

quadit is a very opinionated reimplementation of the fantastic fetchit podman management system.

Please evaluate the following matrix to understand which one would better suit your needs.

fetchit quadit notes
simple file transfer yes no May be considered as a feature if required
ansible yes no Not a quadit goal
kube yes no Raw yaml files are not a quadit goal
raw yes no Not a quadit goal
plain systemd files yes no May be considered as a feature if required
user quadlet no yes Not available in fetchit See fetchit issue
root quadlet no no May be considered as a feature if required
systemd stop no yes Code exists in fetchit but not surfaced in config
systemd start no yes Not implemented in fetchit
auto-update yes no quadit is targeting auto configuration but work is yet to commence
.kube no yes Standard quadlet file type
.volume no yes Standard quadlet file type
.network no yes Standard quadlet file type
.pod no yes Standard quadlet file type
.container no yes Standard quadlet file type

install

From the edge device running a systemd based distro with the latest podman the following commands:

sudo setsebool -P container_manage_cgroup true
mkdir ~/.quadit
curl -o ~/.quadit/config.yaml https://raw.githubusercontent.com/ubiquitous-factory/quadit/main/samples/config.yaml
mkdir -p ~/.config/containers/systemd
curl -o ~/.config/containers/systemd/quadit.container https://raw.githubusercontent.com/ubiquitous-factory/quadit/main/deploy/quadit.container
loginctl enable-linger $USER
systemctl --user daemon-reload
systemctl --user start quadit

environment variables

None of these environment variables should need tweaking but the options are documented as they are available.

Name Default Description
BOOT_URL Bootstrap the service from remote config.yaml hosted at a url. Overrides the local config.yaml
LOCAL 'no' If set to a 'yes' then the exe will assume it's not in a container and run with the local users configuration from $HOME and not use /opt locations
PODMAN_UNIT_PATH $HOME/.config/containers/systemd The location where the container files should be written on the host machine
JOB_PATH Left empty for testing but set to /tmp in the quadit.container file
JOB_FOLDER jobs The name of the folder to save jobs.
XDG_RUNTIME_DIR /run/user/%U Used by systemd to find a user-specific directory in which it can store small temporary files
HOME %u Set by systemd parameter %u but can be overridden in the quadit.container file
PODMAN_SYSTEMD_UNIT %n Set by systemd - the name of the unit
LOG_LEVEL info Can be error, warn, info, debug, trace
SYSTEMCTL_PATH /usr/bin/systemctl Path to the systemctl binary
