Use Docker directly without adding sudo

0.5.2the daemon from the beginning of Docker is always running as root user. The Docker daemon binds to a UNIX socket instead of a TCP port. The UNIX socket is the root user by default, so you must add it when using Docker sudo .

From the 0.5.3 beginning, create a name docker group and then join the user in this group. When the Docker daemon starts, it assigns Unix read and write permissions to the Docker group. This way, you don't have to use the Docker client when you're using it as a user in the Docker group sudo .

if it doesn't already exist. sudo  "${user}"in for # this to takeeffect. sudo gpasswd-a ${user} docker# Restart the Docker daemon. sudo service docker restart
