Victor “got your back” Lowther, CI & build automation czar on our team at Dell, spent a lot of time cleaning up the open source build to make it MUCH easier. The latest build only requires ONE server for all components. To make it repeatable and fast, I’m using a hosted VM from Rackspace Cloud.
Here are the steps that you should follow (cool: if you build before the prereqs are in place, the script will tell you what’s missing).
Note: You must build the discovery image (build_sledgehammer.sh) before building Crowbar. This image does not change very often, so it’s helpful to cache it somewhere (like in the Crowbar cache where it normally lives) and save time.
- Starting from a Rackspace Cloud Ubuntu 10.10 image (512 RAM is OK, $0.03/hr)
- Get libraries for git, RPM, & Ruby: apt-get install git rpm ruby
- Get the sledgehammer repo: git clone git://github.com/dellcloudedge/crowbar-sledgehammer.git
- Go to sledgehammer: cd crowbar-sledgehammer
- Download the CentOS image: curl -o ../CentOS-5.6-x86_64-bin-DVD-1of2.iso http://mirror.cs.vt.edu/pub/CentOS/5.6/isos/x86_64/CentOS-5.6-x86_64-bin-DVD-1of2.iso
- takes some time (10+ mins) even in the cloud
Tell the build where to look for the CentOS image: CENTOS_ISO=~/CentOS-5.6-x86_64-bin-DVD-1of2.iso ./build_sledgehammer.sh
- you may need to change the path of the image if you did not put it in your home directory
- wait a long time while magic happens and the tar gets created
- check out the tar ball in the /bin directory!
- Create the cache location for Sledgehammer: mkdir -p ~/.crowbar-build-cache
- Move the the cache location: cd ~/.crowbar-build-cache
- Extract the Sledgehammer tar: tar xzvf ~/crowbar-sledgehammer/bin/sledgehammer-tftpboot.tar.gz
Or, use the tar copy that I’ve cached it on zehicle.com! Then you can start at step 8.
Now you can build crowbar as per instructions (duplicated below)
- cd ~
- git clone git://github.com/dellcloudedge/crowbar.git
- apt-get update
- apt-get install build-essential mkisofs debootstrap
- kicks off a long download to create the cache (first time only!)
- look in the home directory for the openstack-dev.iso
Of course, you still need to INSTALL CROWBAR (as root, /tftpboot/ubuntu_dvd/extra/install) after you use the ISO to boot a VM. Instructions on that shortly…
