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.
|
|
|
|
You will need `RHEL 6.5`_ or higher, with a RHEL 6 kernel version 2.6.32-431 or higher
|
|
as this has specific kernel fixes to allow Docker to work.
|
|
|
|
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.
|
