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
|
|
===============
|
|
|
|
Install dependencies:
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo apt-get update
|
|
sudo apt-get -qy install git mysql-server libmysqlclient-dev g++\
|
|
python-dev python-pip libffi-dev libssl-dev qemu-utils\
|
|
libxml2-dev libxslt1-dev python-lxml
|
|
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:
|
|
|
|
.. code-block:: bash
|
|
|
|
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.
|
|
|
|
|
|
Set up database for interactive testing:
|
|
|
|
.. code-block:: bash
|
|
|
|
mysql -u root
|
|
|
|
mysql> create database nodepool;
|
|
mysql> GRANT ALL ON nodepool.* TO 'nodepool'@'localhost';
|
|
mysql> flush privileges;
|
|
|
|
Set up database for unit tests:
|
|
|
|
.. code-block:: bash
|
|
|
|
mysql -u root
|
|
mysql> grant all privileges on *.* to 'openstack_citest'@'localhost' identified by 'openstack_citest' with grant option;
|
|
mysql> flush privileges;
|
|
mysql> create database openstack_citest;
|
|
|
|
Note that the script tools/test-setup.sh can be used for the step
|
|
above.
|
|
|
|
Export variable for your ssh key so you can log into the created instances:
|
|
|
|
.. code-block:: bash
|
|
|
|
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):
|
|
|
|
.. code-block:: bash
|
|
|
|
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:
|
|
|
|
.. code-block:: bash
|
|
|
|
nodepool image-list
|
|
|
|
After each run (the fake nova provider is only in-memory):
|
|
|
|
.. code-block:: bash
|
|
|
|
mysql> delete from snapshot_image; delete from node;
|
