Fetch list of AZs from nova if it's not configured 
Nova has an API call that can fetch the list of available AZs. Use it to
provide a default list so that we can provide sane choices to the
scheduler related to multi-node requests rather than just letting nova
pick on a per-request basis.

Nodepool

Nodepool is a service used by the OpenStack CI team to deploy and manage a pool of devstack images on a cloud server for use in OpenStack project testing.

Developer setup

Make sure you have pip installed:

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

Install dependencies:

sudo pip install bindep
sudo apt-get install $(bindep -b nodepool)

mkdir src
cd ~/src
git clone git://git.openstack.org/openstack-infra/system-config
git clone git://git.openstack.org/openstack-infra/nodepool
cd nodepool
sudo pip install -U -r requirements.txt
sudo pip install -e .

If you're testing a specific patch that is already in gerrit, you will also want to install git-review and apply that patch while in the nodepool directory, ie:

git review -x XXXXX

Create or adapt a nodepool yaml file. You can adapt an infra/system-config one, or fake.yaml as desired. Note that fake.yaml's settings won't Just Work - consult ./modules/openstack_project/templates/nodepool/nodepool.yaml.erb in the infra/system-config tree to see a production config.

If the cloud being used has no default_floating_pool defined in nova.conf, you will need to define a pool name using the nodepool yaml file to use floating ips.

Export variable for your ssh key so you can log into the created instances:

export NODEPOOL_SSH_KEY=`cat ~/.ssh/id_rsa.pub | awk '{print $2}'`

Start nodepool with a demo config file (copy or edit fake.yaml to contain your data):

export STATSD_HOST=127.0.0.1
export STATSD_PORT=8125
nodepoold -d -c tools/fake.yaml

All logging ends up in stdout.

Use the following tool to check on progress:
