Permission denied to Docker daemon socket at unix:///var/run/docker.sock

Question

I have this Dockerfile:

FROM chekote/gulp:latest 

USER root
RUN apt-get update \\
      && apt-get upgrade -y \\
      && apt-get i         


        

Answer 1

The error has nothing to do with docker pull or docker image subcommand, but rather that you need to call the docker command as either a user with write access to the docker socket (for example, by being root, using sudo, or by being in the docker group).
