Currently, NTP is configured on zuul workers via puppet[1]. As part of reducing the nodepool image builds' dependency on puppet, this patch adds the necessary package dependencies and service configuration to have NTP running on nodes without needing puppet to install and start it.

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-yaml debootstrap
Install diskimage-builder:
sudo -H pip install diskimage-builder
Build an image
Building an image is simple, we have a script!
bash tools/build-image.sh
See the script for environment variables to set distribution, etc. By default it builds an ubuntu-minimal based image. You should be left with a .qcow2 image file of your selected distribution.
Infra uses the -minimal build type for building Ubuntu/CentOS/Fedora. For example: ubuntu-minimal.
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/newimage
or 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.sh
Other 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.
