Once ready the dockerfile should be added to derivative-maker? No need to have it in a separate repository?
In that case, please fork derivative-maker and add minimal, essential files to derivative-maker. A sub folder docker would probably be good if multiple files are required. However, if convention and suitable, the dockerfile itself could be in the root of the derivative-maker source code folder.
Replied here:
Please drop all of that. Can later be re-introduced at derivative-maker level.
