| This file documents how to build the Crowbar installation DVD image. | ||
|
|
||
| Prerequisites: | ||
| * An unfiltered Internet connection and a decent amount of bandwidth. | ||
| The first time you try to build Crowbar it will need to download | ||
| about 1.5 gigs worth of data from the official Ubuntu apt repositories, | ||
| the Opscode chef repository, the official Openstack 2011.2 PPA, and | ||
| an official Ubuntu CD image mirror. | ||
| * bash version 4 or higher | ||
| build_crowbar.sh uses associative arrays, which bash got in version 4. | ||
| * mkisofs | ||
| The end product of the build script is an ISO image that will be used | ||
| to bootstrap the Crowbar admin node. | ||
| * debootstrap | ||
| The build process needs to download all the .debs and gems that | ||
| Crowbar requires, and we don't want to inadvertently mess up the build | ||
| machine when we do that. All extra packages are downloaded into a | ||
| chrooted minimal Ubuntu intall, and we use debootstrap to enable that. | ||
| * Sudo to root privileges for the following commands: | ||
| * /bin/mount, /bin/umount | ||
| We have to be able to mount and umount the Ubuntu .iso image, as well as | ||
| a tmpfs for debootstrap, and we have to be able to bind mount | ||
| /dev, /dev/pts, /proc, and /sys into the debootstrap chroot environment. | ||
| * /usr/sbin/debootstrap | ||
| debootstrap requires root privileges to run. | ||
| * /bin/cp | ||
| We need to copy things into and out of the debootstrap environment to | ||
| ensure it downloads and caches the right packages. | ||
| * /usr/sbin/chroot | ||
| All our package caching is done in a chroot environment, and chroot | ||
| requires root permissions to run. | ||
|
|
||
| If you want to allow build_crowbar to run the above commands as root | ||
| without having to enter a password each time, the build_crowbar.sh | ||
| includes a sample line you can fix up and add to /etc/sudoers. | ||
| * A working Sledgehammer tftpboot image. | ||
| Sledgehammer is a minimal CentOS 5.6 pxe bootable image that we use | ||
| to perform hardware discovery and configuration for devices that do not | ||
| have low-level management tools for Ubuntu. You can find information on | ||
| how to build Sledgehamemr by reading its HOWTO.Non.Redhat file. We do | ||
| not do fully automated builds of Sledgehammer due to a lack of a CentOS | ||
| equivalent of debootstrap. | ||
|
|
||
| Usage: | ||
| * Run build_crowbar.sh. | ||
| The first time it is run, it will download and cache all the files it | ||
| needs from the official Ubuntu, Chef, and Openstack repositories. It will | ||
| then build the Crowbar installation image, save it to the current | ||
| working directory, and print out a message saying where it saved the image. | ||
| On subsequent runs it will run with the files it cached from the first | ||
| run, unless update-cache is passed as a parameter to the script. | ||
|
|
||
| Customization: | ||
|
|
||
| build_crowbar.sh has several different parameters you can tune, either from | ||
| $HOME/.build-crowbar.conf (for developer use), or from build-crowbar.conf | ||
| in the current directory (for automated builds). | ||
|
|
||
| Here are the parameters you can change through the above configuration files: | ||
| * DEBUG | ||
| If DEBUG is set to anything, build_crowbar will run in debug mode, and will | ||
| print a transcript of everything it is doing to standard error. | ||
| * CACHE_DIR | ||
| This is the default location where build_crowbar.sh will keep the files | ||
| it caches, along with the temporary directories used to mount the | ||
| ISO image, the debootstrap chroot, and the directory we perform the build | ||
| in. It defaults to $HOME/.crowbar-build-cache. | ||
| * ISO_LIBRARY | ||
| This is the default location where the Ubuntu .iso is stored. It defaults | ||
| to $CACHE_DIR/iso | ||
| * ISO_DEST | ||
| This is the location that we will save the Crowbar install iamge to. | ||
| It defaults to the current directory. | ||
| * IMAGE_DIR | ||
| This is the location that we will mount isos in. | ||
| It defaults to $CACHE_DIR/image | ||
| * BUILD_DIR | ||
| This is the directory we will stage the Crowbar build into. | ||
| It defaults to $CACHE_DIR/build | ||
| * UBUNTU_VERSION | ||
| This is the numeric version of Ubuntu we are building Crowbar with. | ||
| Right now we base the build on 10.10 | ||
| * UBUNTU_CODENAME | ||
| This is the one-word codename of $UBUNTU_VERSION. Weird things will | ||
| happen if it is not kept in sync with $UBUNTU_VERSION | ||
| * PPAS | ||
| This is an array of PPA archives to look in to gather packages from. | ||
| This defaults to ("openstack-release/2011.2"), which is the official | ||
| PPA for the Cactus release of Openstack. | ||
| * UBUNTU_ISO_MIRROR | ||
| This is the base URL for the mirror we will try to download the | ||
| Ubuntu server ISO from. It defaults to "http://mirror.anl.gov/pub". | ||
| * SLEDGEHAMMER_PXE_DIR | ||
| This points to the location we expect to find the unpacked Sledgehammer | ||
| PXE boot archive. It defaults to $CACHE_DIR/tftpboot | ||
| * VERSION | ||
| The default version of Crowbar. Defaults to dev. | ||
| * OPENSTACK_ISO | ||
| The name of the ISO that build_crowbar.sh generates. | ||
| Defaults to openstack-$VERSION.iso | ||
| * CROWBAR_DIR | ||
| The directory that the Crowbar source is cheched out to. | ||
| Defaults to the directory that build_crowbar.sh is in. | ||
| * SLEDGEHAMMER_DIR | ||
| The directory that the Sledgehammer source is checked out to. | ||
| Defaults to $CROWBAR_DIR/../sledgehammer | ||
| * VCS_CLEAN_CMD | ||
| This is the command that build_crowbar.sh will run to clean the tree before | ||
| staging the Crowbar build. | ||
| Defaults to 'git clean -f -x -d' | ||
| * DEBS | ||
| This is an array of additional packages that build_crowbar.sh will try | ||
| to populate the .deb cache with. It is empty by default. | ||
| * GEMS | ||
| This is an array of additional Ruby gems that build_crowbar will try to | ||
| populate its .gem cache with. It is empty by default. | ||
| * AMIS | ||
| This is an array of urls for AMI images that you want to prepopulate | ||
| Crowbar with. By default it contains the URL for the official release | ||
| AMI of Ubuntu 11.04 x86_64 server. | ||
| * UBUNTU_CHROOT | ||
| This is the directory that we will mount a tmpfs on when we debootstrap | ||
| a minimal Ubuntu install to prepopulate the deb and gem caches. | ||
| It defaults to $CACHE_DIR/$UBUNTU_CODENAME.chroot | ||
| * DEB_CACHE | ||
| This is the directory that will hold our .deb cache. | ||
| It defaults to $CACHE_DIR/$UBUNTU_CODENAME/debs | ||
| * GEM_CACHE | ||
| This is the directory that will hold our gem cache. | ||
| It defaults to $CACHE_DIR/gems | ||
| * AMI_CACHE | ||
| This is the directory that will hold our AMI cache. | ||
| It defaults to $CACHE_DIR/amis | ||
| * UBUNTU_ISO | ||
| This is the full name of the Ubuntu ISO we will use as the base of the | ||
| Crowbar installation image. | ||
| Defaults to "ubuntu-$UBUNTU_VERSION-server-amd64.iso", which will | ||
| base us on the amd64 server spin of Ubuntu. | ||
| * UBUNTU_DIR | ||
| This is the directory we will mount $UBUNTU_ISO on when we extract files | ||
| from it. | ||
| Defaults to $IMAGE_DIR/$UBUNTU_ISO minus the .iso at the end. |
