JDownloader 2 - Docker Image

DISCLAIMER: As-of 2021, this product does not have a free support team anymore. If you want this product to be maintained, please support on Patreon.
(This product is available under a free and permissive license, but needs financial support to sustain its continued improvements. In addition to maintenance, support and stability there are many desirable features yet to be added.)

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. Please note that this package is also hosted on Github Container Registry, just add ghcr.io/ before the image name (docker pull ghcr.io/jaymoulin/jdownloader instead of jaymoulin/jdownloader)

Docker

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

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

Parameter	Function
-v /opt/JDownloader/app/cfg	Config file folder, saves your configuration on the host
-v /opt/JDownloader/app/logs	Container logs folder, specify it only if you wan to keep logs on the host
-v /opt/JDownloader/app/extensions	Extensions folder, specify it only if you wan to install extensions and keep it on the host
-v /opt/JDownloader/Downloads	Downloads folder (where you put your download mountpoint)

| -u <UID>:<GID> | Add user identifiers to run the container with user priviledges. To obtain such values, run on your host id yourusername, additional information can be found in Docker documentation | -p 3129:3129 | This Network port is required for Direct Connection mode, more information in this section |

Environment Variables

Parameter	Function
FILEMYJDUSER=myjd-user	The docker secret of your MyJDownloader user
FILEMYJDPASSWORD=myjd-password	The docker secret of your MyJDownloader password
MYJDUSER=email@email.com	Your MyJDownloader user
MYJDPASSWORD=foo	Your MyJDownloader password
MYJDDEVICENAME=goofy	The device name that will appear on MyJdownloader portal
XDGDOWNLOADDIR=/opt/JDownloader/Downloads	If you use this variable, set it as per the downloads folder volume!
UMASK="0002"	Defines specific rights for your downloaded files (default: undefined) - Must respect octal form (begins with 0 followed by three numbers between 0 and 7 included) (cf. https://en.wikipedia.org/wiki/Umask)

Identify

There are 3 possibilities to give login password for MyJDownloader:

• Declare FILEMYJDUSER and FILEMYJDPASSWORD which is used with the principle of docker secret : https://docs.docker.com/engine/swarm/secrets/#use-secrets-in-compose. This is the most docker way.
• Declare MYJDUSER and MYJDPASSWORD values which only create environment variable
• If haven't set FILEMYJDUSER, FILEMYJDPASSWORD, MYJDUSER and MYJDPASSWORD values, you can still configure an account by running (Recommended method because it is the most secure but not fully automatic in the docker-compose.)

docker exec jdownloader configure email@email.com 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:

• Asus Merlin: Follow this procedure to enable custom scripts and edit the dnsmasq file, then add the line rebind-domain-ok=/mydns.jdownloader.org/
• FreshTomato: In 'Advanced->DHCP/DNS/Dnsmasq Custom configuration' add rebind-domain-ok=mydns.jdownloader.org
• Fritz!Box: KB Article from JDownloader
• 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)

Install Docker
