dib 1.17.0 includes fixes for debian-minimal to work with the apt-sources element in I69dbaa34be3db3d667e6bd8450ef4ce04a751c70 This moved to having the base repos split out from the usual /etc/apt/sources.list into separate files in /etc/apt/sources.list.d Unfortunately, this puppet module does the cleanup by glob removal of everything in that directory, which is a bit unsafe. I've refactored this slightly so that, like the RedHat path, we only remove the puppetlabs repos files. Change-Id: I5bcd8880a90d238b77aaacfd1eaf0a720552c7ee |

Using diskimage-builder to build devstack-gate nodes
In addition to being able to just download and consume images that are the same as what run devstack-gate, it's easy to make your own for local dev or testing - or just for fun.
Install diskimage-builder
Install the dependencies:
sudo apt-get install kpartx qemu-utils curl python-yamlInstall diskimage-builder:
sudo -H pip install diskimage-builderBuild an image
Building an image is simple, we have a script!
DISTRO="ubuntu" bash tools/build-image.shSee the script for environment variables to set distribution, etc. You should be left with a .qcow2 image file of your selected distribution.
It is a good idea to set TMP_DIR to somewhere with
plenty of space to avoid the disappointment of a full-disk mid-way
through the script run.
While testing, consider exporting DIB_OFFLINE=true, to skip updating the cache.
Mounting the image
If you would like to examine the contents of the image, you can mount it on a loopback device using qemu-nbd.
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=16
sudo mkdir -p /tmp/newimage
sudo qemu-nbd -c /dev/nbd1 /path/to/devstack-gate-precise.qcow2
sudo mount /dev/nbd1p1 /tmp/newimageor use the scripts
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=16
sudo tools/mount-image.sh devstack-gate-precise.qcow2
sudo tools/umount-image.shOther things
It's a qcow2 image, so you can do tons of things with it. You can upload it to glance, you can boot it using kvm, and you can even copy it to a cloud server, replace the contents of the server with it and kexec the new kernel.
