Update README and add TESTING similar to Zuul repo
It looks like the nodepool README has lagged behind on updates since the release of Zuul v3, so we update it with similar content and also add a TESTING file with verified content. Change-Id: I6923a532e3a702def0595998ea2fab5c067da2fe

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.
|
||||
Nodepool is a system for managing test node resources. It supports launching
|
||||
single-use test nodes from cloud providers as well as managing access to
|
||||
pre-defined pre-existing nodes. Nodepool is part of a suite of tools that form
|
||||
a comprehensive test system, including Zuul.
|
||||
|
||||
Developer setup
|
||||
===============
|
||||
The latest documentation for Nodepool is published at:
|
||||
https://zuul-ci.org/docs/nodepool/
|
||||
|
||||
Make sure you have pip installed:
|
||||
The latest documentation for Zuul is published at:
|
||||
https://zuul-ci.org/docs/zuul/
|
||||
|
||||
.. code-block:: bash
|
||||
Getting Help
|
||||
------------
|
||||
|
||||
wget https://bootstrap.pypa.io/get-pip.py
|
||||
sudo python get-pip.py
|
||||
There are two Zuul-related mailing lists:
|
||||
|
||||
Install dependencies:
|
||||
`zuul-announce <http://lists.zuul-ci.org/cgi-bin/mailman/listinfo/zuul-announce>`_
|
||||
A low-traffic announcement-only list to which every Zuul operator or
|
||||
power-user should subscribe.
|
||||
|
||||
.. code-block:: bash
|
||||
`zuul-discuss <http://lists.zuul-ci.org/cgi-bin/mailman/listinfo/zuul-discuss>`_
|
||||
General discussion about Zuul, including questions about how to use
|
||||
it, and future development.
|
||||
|
||||
sudo pip install bindep
|
||||
sudo apt-get install $(bindep -b nodepool)
|
||||
You will also find Zuul developers in the `#zuul` channel on Freenode
|
||||
IRC.
|
||||
|
||||
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 .
|
||||
Contributing
|
||||
------------
|
||||
|
||||
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:
|
||||
To browse the latest code, see: https://git.zuul-ci.org/cgit/nodepool/tree/
|
||||
To clone the latest code, use `git clone https://git.zuul-ci.org/nodepool`
|
||||
|
||||
.. code-block:: bash
|
||||
Bugs are handled at: https://storyboard.openstack.org/#!/project/679
|
||||
|
||||
git review -x XXXXX
|
||||
Code reviews are handled by gerrit at https://review.openstack.org
|
||||
|
||||
After creating a Gerrit account, use `git review` to submit patches.
|
||||
Example::
|
||||
|
||||
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.
|
||||
# Do your commits
|
||||
$ git review
|
||||
# Enter your username if prompted
|
||||
|
||||
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.
|
||||
Join `#zuul` on Freenode to discuss development or usage.
|
||||
|
||||
Export variable for your ssh key so you can log into the created instances:
|
||||
License
|
||||
-------
|
||||
|
||||
.. code-block:: bash
|
||||
Nodepool is free software, licensed under the Apache License, version 2.0.
|
||||
|
||||
export NODEPOOL_SSH_KEY=`cat ~/.ssh/id_rsa.pub | awk '{print $2}'`
|
||||
Python Version Support
|
||||
----------------------
|
||||
|
||||
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
|
||||
nodepool-launcher -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
|
||||
Nodepool requires Python 3. It does not support Python 2.

Testing Nodepool
|

================
|

------------
|
||||
A Quickstart
|
||||
------------
|
||||
|
||||
This is designed to be enough information for you to run your first tests on
|
||||
an Ubuntu 16.04 (or later) host.
|
||||
|
||||
*Install pip*::
|
||||
|
||||
sudo apt-get install python3-pip
|
||||
|
||||
More information on pip here: http://www.pip-installer.org/en/latest/
|
||||
|
||||
*Use pip to install tox*::
|
||||
|
||||
sudo pip3 install tox
|
||||
|
||||
A running zookeeper is required to execute tests.
|
||||
|
||||
*Install zookeeper*::
|
||||
|
||||
sudo apt-get install zookeeperd
|
||||
|
||||
*Start zookeeper*::
|
||||
|
||||
sudo service zookeeper start
|
||||
|
||||
Run The Tests
|
||||
-------------
|
||||
|
||||
*Navigate to the project's root directory and execute*::
|
||||
|
||||
tox
|
||||
|
||||
Note: completing this command may take a long time (depends on system resources)
|
||||
also, you might not see any output until tox is complete.
|
||||
|
||||
Information about tox can be found here: http://testrun.org/tox/latest/
|
||||
|
||||
|
||||
Run The Tests in One Environment
|
||||
--------------------------------
|
||||
|
||||
Tox will run your entire test suite in the environments specified in the project tox.ini::
|
||||
|
||||
[tox]
|
||||
|
||||
envlist = <list of available environments>
|
||||
|
||||
To run the test suite in just one of the environments in envlist execute::
|
||||
|
||||
tox -e <env>
|
||||
so for example, *run the test suite in py35*::
|
||||
|
||||
tox -e py35
