This change adds a plugin interface so that driver can be loaded dynamically. Instead of importing each driver in the launcher, provider_manager and config, the Drivers class discovers and loads driver from the driver directory. This change also adds a reset() method to the driver Config interface to reset the os_client_config reference when reloading the OpenStack driver. Change-Id: Ia347aa2501de0e05b2a7dd014c4daf1b0a4e0fb5
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:
