| <h1>Stack-in-a-Box: Try before you mkfs</h1> |
| <p>Run DevStack from a RAM disk to give it a whirl before making the |
| commitment to install it. We'll cover booting from a USB drive or |
| over the network via PXE. We'll even thow in configuring a home |
| router to handle the PXE boot. You will need a minimum of 3GB |
| for both of these configurations as the RAM disk itself is 2GB.</p> |

| <h2>Prerequisites <small>Hardware</small></h2> |
| </div> |
| |
| <h3>USB Boot</h3> |
| <p><a href="usb-boot.html">This guide</a> covers the creation of a bootable USB drive. Your |
| computer BIOS must support booting from USB.</p> |
| |
| <h3>PXE Boot</h3> |
| <p><a href="pxe-boot.html">This guide</a> covers the installation of OpenWRT on a home router |
| and configuring it as a PXE server, plus the creation of the |
| boot images and PXE support files. |

| <h2>Installation <small>bit blasting</small></h2> |
| </div> |
| |
| <h3>Install DevStack</h3> |
| <p>Grab the latest version of DevStack via https:</p> |
| <pre>sudo apt-get install git -y |
| git clone https://git.openstack.org/openstack-dev/devstack |
| cd devstack</pre> |
| |
| <h3>Prepare the Boot RAMdisk</h3> |
| <p>Pick your boot method and follow the guide to prepare to build |
| the RAM disk and set up the boot process:</p> |
| <ul> |
| <li><a href="usb-boot.html">USB boot</a></li> |
| <li><a href="pxe-boot.html">PXE boot</a></li> |
| </ul> |
| |
| <h3>Fire It Up</h3> |
| <ul> |
| <li>Boot the computer into the RAM disk. The details will vary from |
| machine to machine but most BIOSes have a method to select the |
| boot device, often by pressing F12 during POST.</li> |
| <li>Select 'DevStack' from the Boot Menu.</li> |
| <li>Log in with the 'stack' user and 'pass' password.</li> |
| <li>Create <code>devstack/localrc</code> if you wish to change any |
| of the configuration variables. You will probably want to at |
| least set the admin login password to something memorable rather |
| than the default 20 random characters: |
| <pre>ADMIN_PASSWORD=openstack</pre> |
| </li> |
| <li>Fire up OpenStack! |
| <pre>./run.sh</pre> |
| </li> |
| <li>See the processes running in screen: |
| <pre>screen -x</pre> |
| </li> |
| <li>Connect to the dashboard at <code>http://<ip-address>/</code></li> |
| </ul> |
