Headline

This image allows you to have JDownloader 2 easily installed and controlled via MyJDownloader, thanks to Docker. No cluncky and rusty VNC sessions here!

Installation

Here are some examples to get started with the creation of this container.

Docker

docker run -d --init --restart=always -v </path/to/downloads>:/opt/JDownloader/Downloads -v </path/to/appdata/config>:/opt/JDownloader/cfg --name jdownloader -u $(id -u) -p 3129:3129 -e [email protected] -e MYJD_PASSWORD=bar -e MYJD_DEVICE_NAME=goofy jaymoulin/jdownloader

Docker Compose

services:
   jdownloader:
    image: jaymoulin/jdownloader
    container_name: jdownloader
    restart: always
    user: 1001:100
    volumes:
        - </path/to/appdata/config>:/opt/JDownloader/cfg
        - </path/to/downloads>:/opt/JDownloader/Downloads
        - </path/to/appdata/logs>:/opt/JDownloader/logs #optional
        - /etc/localtime:/etc/localtime:ro #optional
    environment: 
            MYJD_USER: [email protected] #optional (see [Identify](https://github.com/jaymoulin/docker-jdownloader#identify))
            MYJD_PASSWORD: bar #optional (see [Identify](https://github.com/jaymoulin/docker-jdownloader#identify))
            MYJD_DEVICE_NAME: goofy #optional
            XDG_DOWNLOAD_DIR: /opt/JDownloader/Downloads #optional
    ports:
        - 3129:3129 

Note for RPI Zero : specify that you want the arm32v6 image (e.g. jaymoulin/jdownloader:0.7.0-arm32v6) because rpi zero identify itself as armhf which is wrong.

Configuration

You can set many parameters when you configure this container, but you must specify your MyJDownloader login/password to connect to your container.

Configuration values

Environment Variables

Identify

If haven't set MYJD_USER and MYJD_PASSWORD values, you can still configure an account by running (Recommended method)

docker exec jdownloader configure [email protected] password

Other options can be changed on your MyJDownloader account : https://my.jdownloader.org/index.html#dashboard.

Appendixes

Direct Connection Mode

Direct Connection mode (or Direct Connections) improves the use of this container via MyJDownloader GUI and is strongly recommended at least in your LAN.

By enabling this mode, the communication happens directly between the client and the JDownloader server via port 3129 (by default), instead of being routed trough MyJDownloader servers. This enables the GUI to respond much faster with information reliably updating over time. In this mode, MyJDownloader server still handles service related tasks, like the session authentication and notifications.

To enable Direct Connection mode from internet, you need to open and forward port 3129 adjusting your router configuration. Please find more information in this JDownloader's article

DNS Rebind Warning

If you are running a router like Fritz!Box, Asus, OpenWRT, DDWRT, pfSense or any other 3rd party advanced routers you may have DNS Rebind Protection enabled: Direct Connections will not work, you will have to explicitly whitelist mydns.jdownloader.org. The procedure is different for every router, here are some tips:

• Fritz!Box: KB Article from JDownloader
• Asus Merlin: Follow this procedure to enable custom scripts and edit the dnsmasq file, then add the line rebind-domain-ok=/mydns.jdownloader.org/
• OpenWRT: browse to Network>DHCP and DNS>General Settings and add mydns.jdownloader.org to Domain Whitelist
• pfSense: more information here

Direct Connection using a Bridged Network

To get Direct Connection when using a bridged newtwork, please follow these steps:

• Expose 3129 port when creating the container (-p 3129:3129 parameter)
• When JDownloader is running, navigate to Settings > Advanced Settings > Search for "myjdownloader" > Find MyJDownloaderSettings: Custom Device IPs and enter your host LAN IP using this formatting ["192.168.1.10"]. If you need to specify more IPs use ["192.168.1.10","10.10.10.10"]
• Set MyJDownloaderSettings: Manual Local Port to 3129
• Set MyJDownloaderSettings: Direct Connect Mode to Allow lan/wan connections with manual port forwarding
• Restart JDownloader, connections will now be direct

Debugging

You can put a file called jdownloader-block.txt file in your Download folder to pause the container start. This will allow to connect to the container with a shell to debug. (docker exec -it jdownloader sh)
