This repo was created from filter branching the openstack-infra/ config repo. This process brought a lot of cruft with it in the form of directories that we no longer need. This patch removes that cruft so we begin with a tidier repo. Change-Id: Ibffad1b11c0c5f84eedfb0365369f60c4961a0f3 |

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 curlInstall diskimage-builder:
sudo pip install diskimage-builderBuild an image
Building an image is simple, we have a script!
bash tools/build-image.shYou should be left with a file called devstack-gate-precise.qcow2.
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 devstack-gate-precise.qcow2
sudo mount /dev/nbd1 /tmp/newimageOther 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.
