Running the Client
On the Same Host as the Server
In order to connect to the docker server over the Unix socket, the user running the client must have permissions to do so:
[testuser@docker-server ~]$ ls -al /var/run/docker.sock srw-rw----. 1 root docker 0 Apr 25 16:00 /var/run/docker.sock
One way to do that is to make the user a member of "docker" group:
usermod -G docker testuser
