Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it’s transmitted over the Internet. In this step by step guide I will show you how to install Syncthing on your Synology NAS using Portainer.
Install Docker via Synology “Package Center”.
Go to File Station and open the docker folder. Inside the docker folder, create 3 new folders and name it syncthing, data1, data2. Follow the instructions in the image below.
Note: Be careful enter only lowercase, not uppercase letters.
Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the images below.
Once you click on User-defined script a new window will open. Follow the instructions below:
- General: In the Task field type in “Install Syncthing. Uncheck “Enabled” option. Select root User.
- Schedule: Select Run on the following date then select “Do not repeat“.
- Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that click OK.
docker run -d --name=syncthing \ -p 8384:8384 \ -p 22000:22000/tcp \ -p 22000:22000/udp \ -p 21027:21027/udp \ -e PUID=1026 \ -e PGID=100 \ -e TZ=Europe/Bucharest \ -v /volume1/docker/syncthing:/config \ -v /volume1/docker/data1:/data1 \ -v /volume1/docker/data2:/data2 \ --restart always \ ghcr.io/linuxserver/syncthing
Note: Before you paste the code above in the Run command area below, change the value numbers for PUID and PGID with your own values. (Follow my step by step guide on how to do this.)
Note: Before you paste the code above in the Run command area below, change the value for TZ (Select your current Time Zone from this list).
Note: If you have your docker folder in a different volume, then change /volume1/docker/syncthing/config according to your settings. For example: /volume2/docker/syncthing/config or /volume3/docker/syncthing/config etc.
After you click OK on STEP 5 a new warning pop up window will open. Click OK.
After you click OK on STEP 6, select your “Install Syncthing” Task then click the “Run” tab. You will be asked to run Install Syncthing – click Yes. Follow the instructions in the image below.
Go back to STEP 1 or you will deal with karma 🙂
The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:8384 disallow anonymous usage reporting. Follow the instructions in the image below.
Once you logged in for the first time, remember to add a GUI Authentication User and Password. Follow the instructions in the image below.
Enjoy your Syncthing!
