    11  # Rackspace Cloud
    12  
    13  Installing Docker on Ubuntu provided by Rackspace is pretty
    14  straightforward, and you should mostly be able to follow the
    15  [*Ubuntu*](ubuntulinux.md#ubuntu-linux) installation guide.
    16  
    17  **However, there is one caveat:**
    18  
    19  If you are using any Linux not already shipping with the 3.8 kernel you
    20  will need to install it. And this is a little more difficult on
    21  Rackspace.
    22  
    23  Rackspace boots their servers using grub's `menu.lst`
    24  and does not like non `virtual` packages (e.g., Xen compatible)
    25  kernels there, although they do work. This results in
    26  `update-grub` not having the expected result, and
    27  you will need to set the kernel manually.
    28  
    29  **Do not attempt this on a production machine!**
    30  
    31      # update apt
    32      $ apt-get update
    33  
    34      # install the new kernel
    35      $ apt-get install linux-generic-lts-raring
    36  
    37  Great, now you have the kernel installed in `/boot/`, next you need to
    38  make it boot next time.
    39  
    40      # find the exact names
    41      $ find /boot/ -name '*3.8*'
    42  
    43      # this should return some results
    44  
    45  Now you need to manually edit `/boot/grub/menu.lst`,
    46  you will find a section at the bottom with the existing options. Copy
    47  the top one and substitute the new kernel into that. Make sure the new
    48  kernel is on top, and double check the kernel and initrd lines point to
    49  the right files.
    50  
    51  Take special care to double check the kernel and initrd entries.
    52  
    53      # now edit /boot/grub/menu.lst
    54      $ vi /boot/grub/menu.lst
    55  
    56  It will probably look something like this:
    57  
    58      ## ## End Default Options ##

    62      kernel             /boot/vmlinuz-3.8.0-19-generic root=/dev/xvda1 ro quiet splash console=hvc0

    67      kernel             /boot/vmlinuz-3.2.0-38-virtual root=/dev/xvda1 ro quiet splash console=hvc0
    68      initrd             /boot/initrd.img-3.2.0-38-virtual
    69  
    70      title              Ubuntu 12.04.2 LTS, kernel 3.2.0-38-virtual (recovery mode)

    72      kernel             /boot/vmlinuz-3.2.0-38-virtual root=/dev/xvda1 ro quiet splash  single
    73      initrd             /boot/initrd.img-3.2.0-38-virtual
    74  
    75  Reboot the server (either via command line or console)
    76  
    77      # reboot
    78  
    79  Verify the kernel was updated
    80  
    81      $ uname -a
    82      # 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
    83  
    84      # nice! 3.8.
    85  
    86  Now you can finish with the [*Ubuntu*](ubuntulinux.md#ubuntu-linux)
    87  instructions.
