you can try this one. Its build with ARM support so that it should run on Raspberry and the most NAS Systems.
Tebans Docker Image is not Compatible with ARM Processors like that one in your NAS, it was only build for x64 Systems.
Here is the source code:
It is a little bit special because it embeds the plugins that i use already and has python support.
If you build it locally you net buildx instead of docker build, because else docker build will build a image for the hosts CPU Architekture (x64) that will not run on an ARM Processor.
Or you build it when possible direct on the target device.
