O.S.Tezer f87a97f7df Improve code/comment/output markings & display consistency

This PR aims to increase the consistency across the docs for
code blocks and code/comment/output markings.

Rule followed here is "what's visible on the screen should be reflected"

Issue:

 - Docs had various code blocks showing: comments, commands & outputs.
 - All three of these items were inconsistently marked.

Some examples as to how this PR aims to introduce improvements:

1. Removed `> ` from in front of the "outputs". Eg,
`    > REPOSITORY                 TAG       ID              CREATED` replaced with:
`    REPOSITORY                 TAG       ID              CREATED`.

2. Introduced `$` for commands. Eg,
`    sudo chkconfig docker on` replaced with:
`    $ sudo chkconfig docker on`

3. Comments:
`    > # ` replaced with:
`    # `.

> Please note:
> Due to a vast amount of items reviewed and changed for this PR, there
> might be some individually incorrect replacements OR patterns of incorrect
> replacements. This PR needs to be reviewed and if there is anything missing,
> it should be improved or amended.

Red Hat Enterprise Linux

Note

: Docker is still under heavy development! We don't recommend using it in production yet, but we're getting closer with each release. Please see our blog post, Getting to Docker 1.0

Note

: This is a community contributed installation path. The only official installation is using the Ubuntu installation path. This version may be out of date because it depends on some binaries to be updated and published

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.

$ sudo yum -y install docker-io

To update the docker-io package

$ sudo yum -y update docker-io

Now that it's installed, let's start the Docker daemon.

$ sudo service docker start

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

$ sudo chkconfig docker on

Now let's verify that Docker is working.

$ sudo docker run -i -t fedora /bin/bash

Done! Now continue with the Hello World example.

Issues?

If you have any issues - please report them directly in the Red Hat Bugzilla for docker-io component.
