For more information about this image and its history, please see the relevant manifest file (library/fedora) in the docker-library/official-images GitHub repo.
This image serves as the official Fedora image for Fedora 21 and as a semi-official image for Fedora 20 (heisenbug) and rawhide.
The fedora:latest tag will always point to the latest stable release, currently Fedora 21. fedora:latest is now the same as fedora:21.
Fedora rawhide is available via fedora:rawhide and Fedora 20 via fedora:20 and fedora:heisenbug.
The metalink http://mirrors.fedoraproject.org is used to automatically select a mirror site (both for building the image as well as for the yum repos in the container image).
$ docker run fedora cat /etc/yum.repos.d/fedora.repo | grep metalink
metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=$basearch
metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-debug-$releasever&arch=$basearch
metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-source-$releasever&arch=$basearch
This image is officially supported on Docker version 1.5.0.
