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 :doc:`the main article <devstack>`.
|
|
|
|
Setup a Local Environment with an external OpenStack
|
|
----------------------------------------------------
|
|
|
|
1. Install prerequisites
|
|
|
|
On OS X Systems:
|
|
|
|
.. sourcecode:: console
|
|
|
|
# we actually need pip, which is part of python package
|
|
$ brew install python mysql postgresql rabbitmq
|
|
$ pip install virtualenv tox
|
|
|
|
On Ubuntu:
|
|
|
|
.. sourcecode:: console
|
|
|
|
$ sudo apt-get update
|
|
$ sudo apt-get install git-core python-dev python-virtualenv gcc libpq-dev libmysqlclient-dev python-pip rabbitmq-server
|
|
$ sudo pip install tox
|
|
|
|
On Red Hat and related distributions (CentOS/Fedora/RHEL/Scientific Linux):
|
|
|
|
.. sourcecode:: console
|
|
|
|
$ sudo yum install git-core python-devel python-virtualenv gcc python-pip mariadb-devel postgresql-devel erlang
|
|
$ sudo pip install tox
|
|
$ sudo wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.2.2/rabbitmq-server-3.2.2-1.noarch.rpm
|
|
$ sudo rpm --import http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
|
|
$ sudo yum install rabbitmq-server-3.2.2-1.noarch.rpm
|
|
|
|
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
|
|
|
|
2. Grab the code
|
|
|
|
.. sourcecode:: console
|
|
|
|
$ git clone git://github.com/openstack/sahara.git
|
|
$ cd sahara
|
|
|
|
3. Generate Sahara sample using tox
|
|
|
|
.. sourcecode:: console
|
|
|
|
tox -e genconfig
|
|
|
|
4. Create config file from the sample
|
|
|
|
.. sourcecode:: console
|
|
|
|
$ cp ./etc/sahara/sahara.conf.sample ./etc/sahara/sahara.conf
|
|
|
|
5. Look through the sahara.conf and modify parameter values as needed
|
|
For details see
|
|
:doc:`Sahara Configuration Guide </userdoc/configuration.guide>`
|
|
|
|
6. Create database schema
|
|
|
|
.. sourcecode:: console
|
|
|
|
$ tox -e venv -- sahara-db-manage --config-file etc/sahara/sahara.conf upgrade head
|
|
|
|
7. To start Sahara API and Engine processes call
|
|
|
|
.. sourcecode:: console
|
|
|
|
$ tox -e venv -- sahara-api --config-file etc/sahara/sahara.conf --debug
|
|
$ tox -e venv -- sahara-engine --config-file etc/sahara/sahara.conf --debug
|
|
|
|
|
|
Setup local OpenStack dashboard with Sahara plugin

Tips and tricks for dev environment
|
|
-----------------------------------
|
|
|
|
1. Pip speedup
|
|
|
|
Add the following lines to ~/.pip/pip.conf
|
|
|
|
.. sourcecode:: cfg
|
|
|
|
[global]
|
|
download-cache = /home/<username>/.pip/cache
|
|
index-url = <mirror url>
|
|
|
|
Note that the ``~/.pip/cache`` folder should be created manually.
|
|
|
|
2. Git hook for fast checks
|
|
|
|
Just add the following lines to .git/hooks/pre-commit and do chmod +x for it.
|
|
|
|
.. sourcecode:: console
|
|
|
|
#!/bin/sh
|
|
# Run fast checks (PEP8 style check and PyFlakes fast static analysis)
|
|
tox -epep8
|
|
|
|
You can add also other checks for pre-push, for example pylint (see below)
|
|
and tests (tox -epy27).
|
|
|
|
3. Running static analysis (PyLint)
|
|
|
|
Just run the following command
|
|
|
|
.. sourcecode:: console
|
|
|
|
tox -e pylint
|
