My previous guide for JDownloader 2 involved the use of Task Scheduler. Today I’m offering a recommended and excellent alternative for installing the latest JDownloader 2 version via Portainer. JDownloader 2 is a free, open-source download management tool with a huge community of developers that makes downloading as easy and fast as it should be. Users can start, stop or pause downloads, set bandwidth limitations, auto-extract archives and much more. It’s an easy-to-extend framework that can save hours of your valuable time every day. In this step by step guide I will show you how to install JDownloader 2 on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest JDownloader 2 v24.12.1 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 jdownloader2. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Now create two new folders inside the jdownloader2 folder that you have previously created at STEP 3 and name them config and output. 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 jdownloader2. Follow the instructions in the image below.

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

version: "3.9"
services:
  jdownloader2:
    image: jlesage/jdownloader-2
    container_name: JDownloader-2
    hostname: jdownloader2

      - seccomp:unconfined
    ports:

    restart: on-failure:5

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: Before you paste the code above in the Web editor area below, change the value numbers for USER_ID and GROUP_ID with your own values. (Follow my step by step guide on how to do this.) 1026 is my personal PUID value and 100 is my personal PGID value. You have to type in your own values.

• STEP 7

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

• STEP 8

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

• STEP 9

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 10

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:5800 Wait for the installation to be done. ⚠️Note: If you see a black static page after the installation is done, just refresh the page. Follow the instructions in the image below.

• STEP 11

A new pop up window will open. Click OK to automatically set up a Dark Mode theme for your JDownloader 2 instance. Follow the instructions in the image below.

• STEP 12
