How to Install Syncthing on Your Synology NAS

How to Install Syncthing on Your Synology NAS

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.

  2. Schedule: Select Run on the following date then select “Do not repeat“.
  3. 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.
