When the quota available to nodepool is reduced it can happen that some launch attempts fail due to exceeded quota. This needs to be handled gracefully and the quota cache should be invalidated such that the reduced available quota is encountered directly for the following node requests.

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.pyInstall 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 XXXXXCreate 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
nodepool-launcher -d -c tools/fake.yamlAll logging ends up in stdout.
Use the following tool to check on progress:
