My previous guide for Syncthing involved the use of Task Scheduler. Today I’m offering a recommended and excellent alternative for installing the latest Syncthing version via Portainer. 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 Docker & Portainer.

💡Note: This guide works perfectly with the latest Syncthing v1.28.0 release.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it syncthing. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Now create three new folders inside the syncthing folder that you have previously created at STEP 3 and name them config, data1, data2. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 5

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

• STEP 6

In the Name field type in syncthing. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

version: '3.9'
services:
  syncthing:
    image: ghcr.io/linuxserver/syncthing:latest
    container_name: Syncthing
    healthcheck:
     test: curl -f http://localhost:8384/ || exit 1
    restart: on-failure:5
    security_opt:
      - no-new-privileges:true
    environment:
      - PUID=1026
      - PGID=100
      - TZ=Europe/Bucharest
    volumes:
      - /volume1/docker/syncthing/config:/config:rw
      - /volume1/docker/syncthing/data1:/data1:rw
      - /volume1/docker/syncthing/data2:/data2:rw
    ports:
      - 8384:8384
      - 22000:22000/tcp
      - 22000:22000/udp
      - 21027:21027/udp

Note: Before you paste the code above in the Web editor 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 Web editor area below, change the value for TZ. (Select your current Time Zone from this list.)
Note: If you want, you can change the following line /volume1/docker/syncthing/data1 with the path Location of your data folder on your NAS. Also, remember to change :/data1 with the same folder name of your data folder name.
Note: If you want, you can change the following line /volume1/docker/syncthing/data2 with the path Location of another data folder on your NAS. Also, remember to change :/data2 with the same folder name of your data folder name.
