Create a docker group

The docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can access it with sudo. For this reason, docker daemon always runs as the root user.

To avoid having to use sudo when you use the docker command, create a Unix group called dockerand add users to it. When the docker daemon starts, it makes the ownership of the Unix socket read/writable by the docker group.

Warning: The docker group is equivalent to the root user; For details on how this impacts security in your system, see Docker Daemon Attack Surface for details.

To create the docker group and add your user:

Log into Ubuntu as a user with sudo privileges.

This procedure assumes you log in as the ubuntu user.
Create the docker group and add your user.
```
$ sudo usermod -aG docker ubuntu
```
Log out and log back in.

This ensures your user is running with the correct permissions.
Verify your work by running docker without sudo.
```
$ docker run hello-world
```

Execute docker as non-root
As you noticed, docker must be executed with sudo. If you want to execute it with your non-root account, here is what to do:

# create the 'docker' group

$ sudo groupadd docker # probably it already exists

# add your user to the 'docker' group

$ sudo gpasswd -a USER docker # replace USER with your user name

# restart the service

$ sudo service docker restart

You will have to log out and log back in to make the group settings active on your account. After that you can launch docker without sudo:

$ docker images
