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. Closes: https://github.com/dotcloud/docker/issues/5286 Docker-DCO-1.1-Signed-off-by: O.S.

Installing Docker on Ubuntu provided by Rackspace is pretty straightforward, and you should mostly be able to follow the Ubuntu installation guide.
However, there is one caveat:
If you are using any Linux not already shipping with the 3.8 kernel you will need to install it. And this is a little more difficult on Rackspace.
Rackspace boots their servers using grub's menu.lst
and does not like non virtual packages (e.g. Xen compatible)
kernels there, although they do work. This results in
update-grub not having the expected result, and
you will need to set the kernel manually.
Do not attempt this on a production machine!
# update apt
$ apt-get update
# install the new kernel
$ apt-get install linux-generic-lts-raring
Great, now you have the kernel installed in /boot/, next you need to
make it boot next time.
# find the exact names
$ find /boot/ -name '*3.8*'
# this should return some results
Now you need to manually edit /boot/grub/menu.lst,
you will find a section at the bottom with the existing options. Copy
the top one and substitute the new kernel into that. Make sure the new
kernel is on top, and double check the kernel and initrd lines point to
the right files.
Take special care to double check the kernel and initrd entries.
# now edit /boot/grub/menu.lst
$ vi /boot/grub/menu.lst
It will probably look something like this:
## ## End Default Options ##
title Ubuntu 12.04.2 LTS, kernel 3.8.x generic
root (hd0)
kernel /boot/vmlinuz-3.8.0-19-generic root=/dev/xvda1 ro quiet splash console=hvc0
initrd /boot/initrd.img-3.8.0-19-generic
title Ubuntu 12.04.2 LTS, kernel 3.2.0-38-virtual
root (hd0)
kernel /boot/vmlinuz-3.2.0-38-virtual root=/dev/xvda1 ro quiet splash console=hvc0
initrd /boot/initrd.img-3.2.0-38-virtual
title Ubuntu 12.04.2 LTS, kernel 3.2.0-38-virtual (recovery mode)
root (hd0)
kernel /boot/vmlinuz-3.2.0-38-virtual root=/dev/xvda1 ro quiet splash single
initrd /boot/initrd.img-3.2.0-38-virtual
Reboot the server (either via command line or console)
# reboot
Verify the kernel was updated
$ uname -a
# Linux docker-12-04 3.8.0-19-generic #30~precise1-Ubuntu SMP Wed May 1 22:26:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
# nice! 3.8.
Now you can finish with the Ubuntu instructions.
