I was setup new computer in my company, i installed Fedora 25 OS for it.
After i installed docker following the Docker document,
I has a problem about run docker without sudo (reasons are explained
on the Docker document page linked here, I’m not going to repeat them).
So I googled a bit more: developer.fedoraproject.org
According to developer.fedoraproject.org, you’ll have to run the following two commands
in order to get docker executed without sudo.
Basically you’ll add a docker -group and add yourself to it. Both two sites gave a solution,
the docs.docker.com -instructions did not actually work. :smile:

$ sudo groupadd docker && sudo gpasswd -a ${USER} docker && sudo systemctl restart docker
$ newgrp docker
$ docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

Now, docker was run without sudo.
