Setting Up a Development Environment

This page describes how to setup a Sahara development environment by either installing it as a part of DevStack or pointing a local running instance at an external OpenStack. You should be able to debug and test your changes without having to deploy Sahara.

Setup a Local Environment with Sahara inside DevStack

See the main article <devstack>.

Setup a Local Environment with an external OpenStack

Install prerequisites

On OS X Systems:

# we actually need pip, which is part of python package
$ brew install python mysql postgresql
$ pip install virtualenv tox

On Ubuntu:

$ sudo apt-get update
$ sudo apt-get install git-core python-dev python-virtualenv gcc libpq-dev libmysqlclient-dev python-pip
$ sudo pip install tox

On Fedora-based distributions (e.g., Fedora/RHEL/CentOS/Scientific Linux):

$ sudo yum install git-core python-devel python-virtualenv gcc python-pip mariadb-devel postgresql-devel
$ sudo pip install tox

On openSUSE-based distributions (SLES 12, openSUSE, Factory or Tumbleweed):

.. sourcecode:: console

$ sudo zypper in gcc git libmysqlclient-devel postgresql-devel python-devel python-pip python-tox python-virtualenv

Grab the code:

$ git clone git://github.com/openstack/sahara.git
$ cd sahara

Create config file from the sample:

$ cp ./etc/sahara/sahara.conf.sample-basic ./etc/sahara/sahara.conf

Look through the sahara.conf and modify parameter values as needed. For details see Sahara Configuration Guide </userdoc/configuration.guide>
Create database schema:

$ tox -e venv -- sahara-db-manage --config-file etc/sahara/sahara.conf upgrade head

To start Sahara call:

$ tox -e venv -- sahara-all --config-file etc/sahara/sahara.conf --debug

Setup local OpenStack dashboard with Sahara plugin

Tips and tricks for dev environment

Pip speedup

Add the following lines to ~/.pip/pip.conf

[global]
download-cache = /home/<username>/.pip/cache
index-url = <mirror url>

Note that the ~/.pip/cache folder should be created manually.

Git hook for fast checks

Just add the following lines to .git/hooks/pre-commit and do chmod +x for it.

#!/bin/sh
# Run fast checks (PEP8 style check and PyFlakes fast static analysis)
tools/run_fast_checks

You can added the same check for pre-push, for example, run_tests and run_pylint.

Running static analysis (PyLint)

Just run the following command

tools/run_pylint
