"Permission denied while trying to connect to the Docker daemon socket"

[bguastella22]

Hello!
I just tried running the notebook in a Docker container but after running the very first command I get

$ docker pull ghcr.io/neuroimaging-data-science/neuroimaging-data-science:latest
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/images/create?fromImage=ghcr.io%2Fneuroimaging-data-science%2Fneuroimaging-data-science&tag=latest": dial unix /var/run/docker.sock: connect: permission denied

Thanks in advance for any suggestions/help :)
