+Ubuntu 12.04
|
|
|
+------------
|
|
|
+
|
|
|
+1. Build an Ubuntu 12.04 server using the "Next generation cloud servers", with your desired size. It will give you the password, keep that you will need it later.
|
|
|
+2. When the server is up and running ssh into the server.
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ $ ssh root@<server-ip>
|
|
|
+
|
|
|
+3. Once you are logged in you should check what kernel version you are running.
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ $ uname -a
|
|
|
+ Linux docker-12-04 3.2.0-38-virtual #61-Ubuntu SMP Tue Feb 19 12:37:47 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
|
|
|
+
|
|
|
+4. Let's update the server package list
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ $ apt-get update
|
|
|
+
|
|
|
+5. Now lets install Docker and it's dependencies. To keep things simple, we will use the Docker install script. It will take a couple of minutes.
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ $ curl get.docker.io | sudo sh -x
|
|
|
+
|
|
|
+6. Docker runs best with a new kernel, so lets use 3.8.x
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ # install the new kernel
|
|
|
+ $ apt-get install linux-generic-lts-raring
|
|
|
+
|
|
|
+ # update grub so it will use the new kernel after we reboot
|
|
|
+ $ update-grub
|
|
|
+
|
|
|
+ # update-grub doesn't always work so lets make sure. ``/boot/grub/menu.lst`` was updated.
|
|
|
+ $ grep 3.8.0- /boot/grub/menu.lst
|
|
|
+
|
|
|
+ # nope it wasn't lets manually update ``/boot/grub/menu.lst`` (make sure you are searching for correct kernel version, look at initial uname -a results.)
|
|
|
+ $ sed -i s/3.2.0-38-virtual/3.8.0-19-generic/ /boot/grub/menu.lst
|
|
|
+
|
|
|
+ # once again lets make sure it worked.
|
|
|
+ $ grep 3.8.0- /boot/grub/menu.lst
|
|
|
+ title Ubuntu 12.04.2 LTS, kernel 3.8.0-19-generic
|
|
|
+ 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 3.8.0-19-generic (recovery mode)

|
|
|
+ initrd /boot/initrd.img-3.8.0-19-generic
|
|
|
+
|
|
|
+ # much better.
|
|
|
+
|
|
|
+7. Reboot server (either via command line or console)
|
|
|
+8. login again and check to make sure the kernel was updated
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ $ ssh root@<server_ip>
|
|
|
+ $ 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.
|
|
|
+
|
|
|
+9. Make sure docker is running and test it out.
|
|
|
+
|
|
|
+ .. code-block:: bash
|
|
|
+
|
|
|
+ $ start dockerd
|
|
|
+ $ docker pull busybox
|
|
|
+ $ docker run busybox /bin/echo hello world
|
|
|
+ hello world
|
|
|
+
|
|
|
+Alternate install
|
|
|
+^^^^^^^^^^^^^^^^^
|
|
|
+If you don't want to run the get.docker.io script and want to use packages instead, you can use the docker PPA. Here is how you use it. Replace step 5 with the following 3 steps.
|
|
|
+
|
|
|
+1. Add the custom package sources to your apt sources list. Copy and paste the following lines at once.
|
|
|
+
|
|
|
+.. code-block:: bash
|
|
|
+
|
|
|
+ $ sudo sh -c "echo 'deb http://ppa.launchpad.net/dotcloud/lxc-docker/ubuntu precise main' >> /etc/apt/sources.list"
|
|
|
+
|
|
|
+
|
|
|
+2. Update your sources. You will see a warning that GPG signatures cannot be verified.
|
|
|
+
|
|
|
+.. code-block:: bash
|
|
|
+
|
|
|
+ $ sudo apt-get update
|
|
|
+
|
|
|
+
|
|
|
+3. Now install it, you will see another warning that the package cannot be authenticated. Confirm install.
|
|
|
+
|
|
|
+.. code-block:: bash
|
|
|
+
|
|
|
+ $ apt-get install lxc-docker
|

|
|

|
|
|
+7. Reboot server (either via command line or console)
|
|
