To run Uptime Kuma on Fedora as a systemd-managed service, place a Quadlet .container file in the directory for your chosen mode, publish host port 3001 to container port 3001, and persist /app/data on local storage. Quadlet turns that file into an ordinary systemd service, so you start, stop, and inspect Uptime Kuma with systemctl rather than with manual podman run commands.
The Uptime Kuma project documents the container image and core runtime settings, and Podman documents how Quadlet generates services. The project does not publish a Quadlet file, so the unit in this guide is an adaptation of those documented settings. Validate it on your Fedora release before relying on it.

What you need before you start
- A Fedora host with Podman installed and a user with
sudorights (for rootful) or a dedicated service account (for rootless). - cgroup v2. Quadlet requires it. Check with
podman info --format {{.Host.CgroupsVersion}}; the output should bev2. - Local storage for the database. Uptime Kuma stores its SQLite database in
/app/data. The project states that POSIX file-lock support is required to avoid SQLite database corruption, and it warns about locking problems commonly seen with NFS. Use a directory on a local filesystem or a Podman volume. Do not place the database on NFS. - Port 3001 free on the host, or a different host port you are prepared to map.
You do not need Node.js, Git, or PM2. The project’s documentation lists those for its native, non-container installation path, which also names Fedora among supported distributions. The container path in this guide does not use them.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
Choose rootful or rootless
Both modes use the same unit file. They differ in where the file lives, which systemd manager runs it, and which account owns the container.

| Aspect | Rootful (system service) | Rootless (user service) |
|---|---|---|
| Quadlet location | /etc/containers/systemd/ |
~/.config/containers/systemd/ of the service user |
| Reload and control | sudo systemctl daemon-reload, sudo systemctl start uptime-kuma.service |
systemctl --user daemon-reload, systemctl --user start uptime-kuma.service |
| Best fit | Host-level administration of the service | Keeping the container under a dedicated account’s service manager |
| Boot behavior | Managed by the system manager | Depends on the account’s user-manager setup (see the rootless steps below) |
| Volume path in the file | An absolute path such as /srv/uptime-kuma/data |
An absolute path inside the service user’s home, such as /home/kuma/uptime-kuma/data |
Write the Quadlet unit
Create uptime-kuma.container with the following content. Adjust only the volume path if your layout differs.
[Unit]
Description=Uptime Kuma monitoring
After=network-online.target
Wants=network-online.target
[Container]
Image=docker.io/louislam/uptime-kuma:2
ContainerName=uptime-kuma
PublishPort=3001:3001
Volume=/srv/uptime-kuma/data:/app/data:Z
[Service]
Restart=always
TimeoutStartSec=900
[Install]
WantedBy=default.targetWhat each part does:
Image=uses the project’s documentedlouislam/uptime-kuma:2image, written with its fully qualified registry name so Podman does not need to choose a registry. Check the project’s installation page at deployment time, because the recommended tag can change.PublishPort=3001:3001maps host port 3001 to container port 3001, the port the project documents. To use another host port, change only the left side, for examplePublishPort=8080:3001.Volume=binds a host directory to/app/data. The:Zoption relabels the directory for SELinux, which Fedora enforces by default. Use it only on a directory dedicated to Uptime Kuma, because the relabel applies to everything in that directory.TimeoutStartSec=900in the[Service]section gives the first start enough time to pull the image. The default systemd startup limit is 90 seconds.[Install]withWantedBy=default.targetis the documented Quadlet pattern for startup. Quadlet units are generated rather than enabled like ordinary static service files, so usestartand verify boot behavior after a reboot.
Rootful setup
- Create the data directory:
sudo mkdir -p /srv/uptime-kuma/data. - Create the unit:
sudo nano /etc/containers/systemd/uptime-kuma.containerand paste the file above. - Make systemd read the new file:
sudo systemctl daemon-reload. - Start the service:
sudo systemctl start uptime-kuma.service. - Confirm the state:
sudo systemctl status uptime-kuma.serviceshould showactive (running), andsudo podman psshould list theuptime-kumacontainer. - Open
http://localhost:3001on the host to reach the setup screen. - Reboot and run
systemctl is-active uptime-kuma.service. It should printactive.
Rootless setup
- Switch to the service account, for example
sudo -iu kuma. - Create the directories:
mkdir -p ~/.config/containers/systemd ~/uptime-kuma/data. - Create
~/.config/containers/systemd/uptime-kuma.containerwith the same content, changing the volume line to the absolute path, for exampleVolume=/home/kuma/uptime-kuma/data:/app/data:Z. - Reload the user manager:
systemctl --user daemon-reload. - Start the service:
systemctl --user start uptime-kuma.service, then check it withsystemctl --user status uptime-kuma.service. - For the service to run at boot without an interactive login, check that lingering is enabled for the account. Run
loginctl show-user kuma --property=Lingerand, if it reportsLinger=no, enable it from an administrator account withsudo loginctl enable-linger kuma. - Reboot and confirm with
systemctl --user is-active uptime-kuma.servicerun as that account.
Networking and reverse proxy
Local access on the host works with port 3001 published as shown. To reach Uptime Kuma from other machines, open the port in the firewall, for example sudo firewall-cmd --permanent --add-port=3001/tcp followed by sudo firewall-cmd --reload.

Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
Unit not found after systemctl start |
The file is in the wrong directory or has the wrong extension, or daemon-reload was skipped |
Confirm the path for your mode, check the .container extension, and run daemon-reload again |
| Start fails on the first run | The image pull exceeded systemd’s 90-second default startup limit | Pre-pull with podman pull, or increase TimeoutStartSec in the [Service] section |
| Quadlet does not generate a service | The host is not running cgroup v2 | Run podman info --format {{.Host.CgroupsVersion}} and resolve the cgroup version before continuing |
| Database errors or corruption | /app/data is on NFS or another filesystem without POSIX file-lock support |
Move the data to a local directory or Podman volume and restore from backup if needed |
Permission denied on /app/data |
The SELinux label is missing or the directory ownership does not match the container user | Keep :Z on a dedicated directory and check ownership of the host directory |
| Port 3001 already in use | Another service uses the host port | Change the host side of PublishPort=, for example 8080:3001 |
| Rootless service stops at logout or after reboot | Lingering is not enabled for the service account | Enable lingering with sudo loginctl enable-linger for that account |
| Live updates fail behind a proxy | Upgrade and Connection headers are not forwarded |
Add header forwarding in the proxy configuration |
