| |
| Please note this is a community contributed installation path. The only 'official' installation is using the |
| :ref:`ubuntu_linux` installation path. This version may sometimes be out of date. |
| |
| |
| Installing Docker on Ubuntu proviced 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 makes ``update-grub`` to not have the expected result, and you 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 kernel installed in /boot/, next is 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 kernel |
| and initrd point to the right files. |
| |
| Make 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: |
| |
| :: |
| |

| 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 |
| |

| root (hd0) |

| 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 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. |
