Docker is available in **Fedora 19 and later**. Please note that due to
the current Docker limitations Docker is able to run only on the **64
bit** architecture.
Docker is supported only on Fedora 20 and later,

## Installation
The `docker-io` package provides Docker on Fedora.
For `Fedora 20`, the `docker-io` package provides Docker.
If you have the (unrelated) `docker` package installed already, it will

it. To proceed with `docker-io` installation on Fedora 19, please remove
`docker` first.

Fedora 20, please remove `docker` first.
$ sudo yum -y remove docker
For Fedora 21 and later, the `wmdocker` package will
provide the same functionality as `docker` and will
also not conflict with `docker-io`.
$ sudo yum -y install wmdocker
$ sudo yum -y remove docker

For `Fedora 21 and later`, there are no package conflicts as the system

$ sudo yum -y update docker-io

## Granting rights to users to use Docker
Fedora 19 and 20 shipped with Docker 0.11. The package has already been updated
to 1.0 in Fedora 20. If you are still using the 0.11 version you will need to
grant rights to users of Docker.
The `docker` command line tool contacts the `docker` daemon process via a
socket file `/var/run/docker.sock` owned by group `docker`. One must be
member of that group in order to contact the `docker -d` process.

[recommended](https://lists.projectatomic.io/projectatomic-archives/atomic-devel/2015-January/msg00034.html)
to use `sudo` for docker commands, if users wish to avoid it, an administrator can
create a `docker` group, have it own `/var/run/docker.sock`, and add users to this group.
$ usermod -a -G docker login_name
Adding users to the `docker` group is *not* necessary for Docker versions 1.0
and above.
$ sudo groupadd docker
$ sudo chown root:docker /var/run/docker.sock
