Red Hat Enterprise Linux / CentOS
=================================

.. include:: install_header.inc

.. include:: install_unofficial.inc

Docker is available for **RHEL/CentOS 6**.

Please note that this package is part of a `Extra Packages for Enterprise Linux (EPEL)`_, a community effort to create and maintain additional packages for RHEL distribution.

Please note that due to the current Docker limitations Docker is able to run only on the **64 bit** architecture.

Installation
------------

1. Firstly, let's make sure our RHEL host is up-to-date.

.. code-block:: bash

    sudo yum -y upgrade

2. Next you need to install the EPEL repository. Please follow the `EPEL installation instructions`_.

3. Next let's install the ``docker-io`` package which will install Docker on our host.

.. code-block:: bash

   sudo yum -y install docker-io

4. Now it's installed lets start the Docker daemon.

.. code-block:: bash

    sudo service docker start

If we want Docker to start at boot we should also:

.. code-block:: bash

   sudo chkconfig docker on

5. Now let's verify that Docker is working.

.. code-block:: bash

   sudo docker run -i -t ubuntu /bin/bash

**Done!**, now continue with the :ref:`hello_world` example.
