[Solved] Little issue with Docker - Ubuntu

[MatthieuGG]

Summary

Dear, I have just read your paper about fMRIflows, and I was thrilled to try since I am a huge fMRIprep enjoyer. I just had a little issue with Docker, that needed sudo to work perfectly.

Actual behavior - Script/Workflow details

touhara@touhara-Precision-5820-Tower:~$ sudo docker run hello-world
