- :title: Requirements and Installation on Red Hat Enterprise Linux
- :description: Please note this project is currently under heavy development. It should not be used in production.
- :keywords: Docker, Docker documentation, requirements, linux, rhel, centos
- .. _rhel:
- Red Hat Enterprise Linux
- ========================
- .. include:: install_header.inc
- .. include:: install_unofficial.inc
- Docker is available for **RHEL** on EPEL. These instructions should work for
- both RHEL and CentOS. They will likely work for other binary compatible EL6
- distributions as well, but they haven't been tested.
- Please note that this package is part of `Extra Packages for Enterprise
- Linux (EPEL)`_, a community effort to create and maintain additional packages
- for the RHEL distribution.
- Also note that due to the current Docker limitations, Docker is able to run
- only on the **64 bit** architecture.
- Installation
- ------------
- Firstly, you need to install the EPEL repository. Please follow the `EPEL installation instructions`_.
- The ``docker-io`` package provides Docker on EPEL.
- If you already have the (unrelated) ``docker`` package installed, it will
- conflict with ``docker-io``. There's a `bug report`_ filed for it.
- To proceed with ``docker-io`` installation, please remove
- ``docker`` first.
- Next, let's install the ``docker-io`` package which will install Docker on our host.
- .. code-block:: bash
- sudo yum -y install docker-io
- To update the ``docker-io`` package
- .. code-block:: bash
- sudo yum -y update docker-io
- Now that it's installed, let's 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
- Now let's verify that Docker is working.
- .. code-block:: bash
- sudo docker run -i -t fedora /bin/bash
- **Done!**, now continue with the :ref:`hello_world` example.
- Issues?
- -------
- If you have any issues - please report them directly in the `Red Hat Bugzilla for docker-io component`_.
