Just in case there is anyone else looking for Docker Slicer GUI, I also have one based on Ubuntu Desktop, could not rebuild Steve’s Image
Only change I made is to download and extract Slicer first, then place it in the folder with the dockerfile, and I also modify slicerrc.py to enable me copy and load files directly to the container so that it is open with the needed files.
I also create volumes for sending files in and reading files out.
Let me know if you are able to have fun with this.
