Hello
I have found the Docker images for the above-mentioned Euler OS.
https://github.com/euleros/euleros-docker-images/blob/master/2.2/EulerOS-2.2... https://en.wikipedia.org/wiki/Docker_(software)
However, after opening it, I find it to be "shared object" files.
It is not the source code, which should include source file and headers.
And according to the https://github.com/euleros/euleros-docker-images/blob/master/README.md They claim it to be GPLv2, which is in contradiction with the EULA inside their compiled system, interestingly.
So I am considering open an issue there, asking for it to be open-source.
