Own docker as rock-on

Rock-ons
1

Hey guys, im very new to docker, only played a bit with my nextcloud instance and Libreoffice online with.

So im a bit confused how it works to create your own rock-on. I want to user JDownloader on my Rockstor, so i found this docker image: https://hub.docker.com/r/aptalca/docker-jdownloader2/ now i realy dont know how to install it as an rock-on

@Fire_Fly40235 Hello and welcome to the Rockstor community.

I think what you are looking for is the Readme File in our rockon-registry. That describes what is required to create your own custom Rockon. Best have a read and then ask further questions as your run into problems, if in fact you do. Then once you have it up and running you can submit it to that repository where upon it will become available to all Rockstor users.

The vast majority of the Rockon definition files, all viable in that repository, were created by forum members so there is quite a lot of knowledge here about how to get them up and running. Also just looking at the other definitions can help a lot on seeing what is required. Basically it’s one json formatted file per Rockon to define what is needed to install it successfully.

Hope that helps.

@Fire_Fly40235 Hello again. From a really quick look I think you have a couple of extra “,” in there around line 29, and 33.
Try the following json validation web page:

I.e past you json in there and press “Validate JSON”. So you could make those formatting changes and then re-check how that looks / runs.

Hope that helps and it looks like you are pretty close.
