If you want to use docker run command:
ForPGID and PUID please enter the UID/GID of the user who should own the files outside the container.docker run -d \
--name urbackup \
--restart unless-stopped \
-e PUID=1000 \

#cap_add:

```
After running the container Urbackup should be reachable on the web interface on port :55414
## Building locally
Please use the provided `build.sh` script:
./build.sh
On default the script will build a container for amd64 with the most recent stable version.
To build for other architectures the script accepts following argument:
`./build.sh [ARCH] [VERSION]`
`[ARCH]` can be `amd64`, `i386`, `armhf` or `arm64`; `[Version]` can be an existing version of UrBackup-server
For example if you want to build an image for version 2.4.10 on armhf use the following command:
./build.sh armhf 2.4.10
```Serve UrBackup on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.
Proxying urbackup.example.com to http://UrBackup:55415
Add this to your Caddyfile
urbackup.example.com {
reverse_proxy http://UrBackup:55415
}Check the logs first
Nine times out of ten the logs tell you exactly what went wrong.
- In Portainer, go to Containers, click the container, then Logs. Or run
docker logs UrBackup - Exit codes help too:
137means killed, usually out of memory.126or127means the command inside the image is broken.
Port already in use
If deployment fails with "Bind for 0.0.0.0:55415 failed: port is already allocated", something else on your server is using that port.
- Find what's using it:
sudo ss -tlnp | grep :55415 - Stop the other service, or pick a different host port. In
55415:55415only the left number is yours to change, the right one belongs to the app.
Running but the page won't load
The container is up but nothing appears in your browser.
- Use your server's real IP:
http://your-server-ip:55415. The 0.0.0.0 link Portainer shows isn't a real address. - Give it a minute after first deploy, UrBackup can take a while to initialise.
- Make sure your firewall allows the port, e.g.
sudo ufw allow 55415
Permission denied on volumes
If the logs show "permission denied", the app can't write to its data folder on the host.
- Fix the ownership:
sudo chown -R 1000:1000 /portainer/Files/AppData/Config/urbackup(and the same for the other mapped folders) - Or set the
PUIDandPGIDvariables (defaults 1000:1000) to match your own user, found withid $USER
Image won't pull
Test the pull directly on the host: docker pull uroni/urbackup-server:latest
- "manifest unknown" means the tag no longer exists. This template uses
latest, so try pinning a specific version instead. - "toomanyrequests" is the Docker Hub rate limit. Log in with
docker loginto raise it. - "no space left on device" means a full disk. Reclaim space with
docker system prune
"exec format error"
This means the image was built for a different CPU architecture than your server.
- This image supports:
amd64, arm64, arm/v7, 386, arm - Check yours with
uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.
Container keeps restarting
The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.
- Check the logs right after a restart, the last few lines before it died are the useful ones.
- Get the exit code with
docker inspect UrBackup --format '{{.State.ExitCode}}' - Still stuck? Redeploy once with the restart policy set to
noso the failure stays visible.
Raise an issue
Found something which isn't working as it should? Here's how to report it.
- Bug within the app: Open an issue within UrBackup's repo
- Template not working: Open an issue on novaspirit/pi-hosted
- This website not working: Open an issue on lissy93/portainer-templates
A single container
UrBackup runs as one container, the simplest kind of app here. Just the one image to pull and nothing else wired up alongside it.
The app image
An image is the app packed up ready to go, everything UrBackup needs bundled into one download. This template pulls uroni/urbackup-server:latest, which Docker fetches once (about 79 MB) and then starts your own copy from.
Where the image comes from
Docker pulls its images from registries, public libraries of ready-built apps. UrBackup's comes from Docker Hub, published by uroni.
Version tags
The bit after the colon in the image name is the version tag. Here it's latest, which always points at the newest build, so a redeploy can bump you to a newer release without you asking. Newest right now is 2.5.x-zfs. Pin a specific tag if you would rather stay on one version.
Which machines it runs on
Every image is built for particular CPU types. This one ships for amd64, arm64, arm/v7, 386, arm, so it runs on both regular x86 servers and ARM boards like a Raspberry Pi.
Ports
A port is the door the app answers on. A mapping like 55415:55415 means it's reachable on port 55415 of your server, where the left number is yours to change and the right one belongs to the app. It opens:
55415:5541555414:55414
Volumes
A volume is where UrBackup keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:
/var/urbackupfrom/portainer/Files/AppData/Config/urbackupon the host/backupfrom/portainer/backupson the host
Environment variables
Environment variables are the settings you hand over when you deploy, things like a password or a timezone. UrBackup takes 2 of them, all with defaults you can leave alone or tweak:
PUID, defaults to1000PGID, defaults to1000
Restart policy
The restart policy here is unless-stopped, so Docker restarts UrBackup after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).
Users and permissions
The PUID and PGID settings tell it which user and group to act as on your host. Point them at your own account (find yours with id $USER) so the files it writes into your mounted folders come out owned by you rather than root.
Networking
Nothing custom is set, so UrBackup sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.
Container name
Once it's deployed, Portainer names the container UrBackup. That's what you'll spot in the containers list and use in commands like docker logs UrBackup.
Platform
The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.
Portainer app templates
Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set UrBackup up. Add the template list to Portainer once, then deploying UrBackup is a click rather than a wall of config.
