Hello Fedora with docker in 3 steps

It really is this simple,

1. sudo yum install -y docker-io

2. sudo systemctl start docker

3. sudo docker run mattdm/fedora cat /etc/system-release

Bonus, for when you want to go deeper -

If you don’t want to use sudo all the time, which you shouldn’t want to do, you add yourself to the docker group,

$ sudo usermod -a -G docker $USER

If you don’t want to log out and back in, make your new group effective immediately,

$ su - $USER
$ groups | grep -q docker && echo Good job || echo Try again

If you want to run a known image, search for it on https://index.docker.io or on the command line,

$ docker search fedora

Try out a shell with,

$ docker run -i -t mattdm/fedora /bin/bash
