    As this post (http://blog.docker.io/2013/11/docker-0-7-docker-now-runs-on-any-linux-distribution/) claims that docker now have "Standard Linux support" including RHEL, but in the documents (http://docs.docker.io/en/latest/installation/kernel/) it specifies that Linux version 3.8 or above is required. RHEL and CentOS still on the kernel 2.6 stage. Can someone explain to me if they are supported or not?

    This has been discussed a lot on the docker-dev mailing list, and it seems that yes, with a bit of tweaking it does run on CentOS.

    You can use this vagrant configuration to test if the support is good enough for you: https://github.com/blalor/vagrant-centos64-docker

    If you're happy with how it works, you can then configure your CentOS with the bootstrap.sh script included in the aforementioned repository.

    Fedora does not correspond directly to RHEL or CentOS; RHEL is built from pieces of Fedora, but not the whole thing.

    The latest RHEL and CentOS versions are directly comparable, except for prerelease versions. Older versions of RHEL have a "u" to indicate the update release where CentOS has a "." to indicate the minor version.

    Also note that delays in having gotten CentOS 6 out mean that CentOS 6.0 is slightly ahead of RHEL 6.0, although the CentOS developers plan to have this straightened out with 6.1.

    There is no relation between fedora version and RHEL, Centos version. Fedora is a community project with a release in each 6 months. But RHEL and its clone Centos are enterprise-grade distributions with long release gap. CentOS is a clone of RHEL with branding/artwork etc removed from RHEL. Since the logo, artwork etc are the property of Redhat, it is not possible for a community distro to use that. CentOS removes the brading from RHEL and releases the Centos distro. Centos follows the same release cycle as RHEL but lags behind RHEL. RHEL 6 was released this year and CentOS will release version 6 in 2011.
