- :title: Rackspace Cloud Installation
- :description: Installing Docker on Ubuntu proviced by Rackspace
- :keywords: Rackspace Cloud, installation, docker, linux, ubuntu
- Rackspace Cloud
- ===============
- .. include:: install_unofficial.inc
- Installing Docker on Ubuntu provided by Rackspace is pretty
- straightforward, and you should mostly be able to follow the
- :ref:`ubuntu_linux` 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!**
- .. code-block:: bash
- # 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.
- .. code-block:: bash
- # 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.
- .. code-block:: bash
- # 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)
- .. code-block:: bash
- # reboot
- Verify the kernel was updated
- .. code-block:: bash
- 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 :ref:`ubuntu_linux` instructions.
