Developer Quick-Start
|
|
=====================
|
|
|
|
This is a quick walkthrough to get you started developing code for Zun.
|
|
This assumes you are already familiar with submitting code reviews to
|
|
an OpenStack project.
|
|
|
|
.. seealso::
|
|

|
http://docs.openstack.org/infra/manual/developers.html
|
|
|
|
Setup Dev Environment
|
|
=====================
|
|
|
|
Install OS-specific prerequisites::
|
|
|
|
# Ubuntu/Debian:
|
|
sudo apt-get update
|
|
sudo apt-get install -y libmysqlclient-dev build-essential python-dev \
|
|
python3.4-dev git
|
|
|
|
Install pip::
|
|
|
|
curl -s https://bootstrap.pypa.io/get-pip.py | sudo python
|
|
|
|
Install common prerequisites::
|
|
|
|
sudo pip install virtualenv flake8 tox testrepository git-review
|
|
|
|
You may need to explicitly upgrade virtualenv if you've installed the one
|
|
from your OS distribution and it is too old (tox will complain). You can
|
|
upgrade it individually, if you need to::
|
|
|
|
sudo pip install -U virtualenv
|
|
|
|
Zun source code should be pulled directly from git::
|
|
|
|
# from your home or source directory
|
|
cd ~
|
|
git clone https://git.openstack.org/openstack/zun
|
|
cd zun
|
|
|
|
All unit tests should be run using tox. To run Zun's entire test suite::
|
|
|
|
# run all tests (unit and pep8)
|
|
tox
|
|
|
|
To run a specific test, use a positional argument for the unit tests::
|
|
|
|
# run a specific test for Python 2.7
|
|
tox -epy27 -- test_conductor
|
|
|
|
You may pass options to the test programs using positional arguments::
|
|
|
|
# run all the Python 2.7 unit tests (in parallel!)
|
|
tox -epy27 -- --parallel
|
|
|
|
To run only the pep8/flake8 syntax and style checks::
|
|
|
|
tox -epep8
|
|
|
|
Exercising the Services Using Devstack
|
|
======================================
|
|
|
|
This session has only been tested on Ubuntu 14.04 (Trusty).
|
|
We recommend users to select one of it if it is possible.
|
|
|
|
Clone devstack::
|
|
|
|
# Create a root directory for devstack if needed
|
|
sudo mkdir -p /opt/stack
|
|
sudo chown $USER /opt/stack
|
|
|
|
git clone https://git.openstack.org/openstack-dev/devstack /opt/stack/devstack
|
|
|
|
We will run devstack with minimal local.conf settings required to enable
|
|
required OpenStack services::
|
|
|
|
cat > /opt/stack/devstack/local.conf << END
|
|
[[local|localrc]]
|
|
HOST_IP=$(ip addr | grep 'state UP' -A2 | tail -n1 | awk '{print $2}' | cut -f1 -d'/')
|
|
DATABASE_PASSWORD=password
|
|
RABBIT_PASSWORD=password
|
|
SERVICE_TOKEN=password
|
|
SERVICE_PASSWORD=password
|
|
ADMIN_PASSWORD=password
|
|
enable_plugin zun https://git.openstack.org/openstack/zun
|
|
END
|
|
|
|
More devstack configuration information can be found at
|
|
http://docs.openstack.org/developer/devstack/configuration.html
|
|
|
|
More neutron configuration information can be found at
|
|
http://docs.openstack.org/developer/devstack/guides/neutron.html
|
|
|
|
Run devstack::
|
|
|
|
cd /opt/stack/devstack
|
|
./stack.sh
|
|
|
|
Prepare your session to be able to use the various openstack clients including
|
|
nova, neutron, and glance. Create a new shell, and source the devstack openrc
|
|
script::
|
|
|
|
source /opt/stack/devstack/openrc admin admin
|
|
|
|
Using the service
|
|
=================
|
|
|
|
We will create a container that pings the address 8.8.8.8 four times::
|
|
|
|
zun create --name test --image cirros --command "ping -c 4 8.8.8.8"
|
|
zun start test
|
|
|
|
You should see a similar output to::
|
|
|
|
zun list
|
|
+--------------------------------------+------+---------+--------+-------------------+--------+
|
|
| uuid | name | status | image | command | memory |
|
|
+--------------------------------------+------+---------+--------+-------------------+--------+
|
|
| 010fde12-bcc4-4857-94e3-e3f0e301fc7f | test | Stopped | cirros | ping -c 4 8.8.8.8 | None |
|
|
+--------------------------------------+------+---------+--------+-------------------+--------+
|
|
|
|
zun logs test
|
|

Delete the container::
|
|
|
|
zun delete test
