birdhousebuilder.recipe.pywps 0.1.3

A Buildout recipe to install and configure PyWPS Web Processing Service with Anaconda.

Latest Version: 0.2.6

Introduction

birdhousebuilder.recipe.pywps is a Buildout recipe to install and configure PyWPS with Anaconda. PyWPS is a Python implementation of a Web Processing Service (WPS). PyWPS will be deployed as a Supervisor service and is available on a Nginx web server.

Birdhousebuilder recipes are used to build Web Processing Service components (Phoenix, Malleefowl, Nighthawk, FlyingPigeon, …) of the ClimDaPs project. All Birdhousebuilder recipes need an existing Anaconda installation.

Usage

The recipe requires that Anaconda is already installed. It assumes that Anaconda is installed at the default location in your home directory ~/anaconda. Otherwise you need to set the Buildout option anaconda-home to the correct location.

It installs the pywps package from a conda channel and setups a PyWPS output folder in ~/anaconda/var/lib/pywps. It deploys a Supervisor configuration for PyWPS in ~/anaconda/etc/supervisor/conf.d/pywps.conf. Supervisor can be started with ~/anaconda/etc/init.d/supervisor start.

The recipe will install the nginx package from a conda channel and deploy a Nginx site configuration for PyWPS. The configuration will be deployed in ~/anaconda/etc/nginx/conf.d/pywps.conf. Nginx can be started with ~/anaconda/etc/init.d/nginx start.

By default PyWPS will be available on http://localhost:8091/wps?service=WPS&version=1.0.0&request=GetCapabilities.

The recipe depends on birdhousebuilder.recipe.conda, birdhousebuilder.recipe.supervisor and birdhousebuilder.recipe.nginx.

Supported options

The recipe supports the following options:

anaconda-home
Buildout option with the root folder of the Anaconda installation. Default: $HOME/anaconda.
hostname
The hostname of the pycsw service (nginx). Default: localhost
port
The port of the pycsw service (nginx). Default: 8091
sites
The name of your WPS project (used for config names and folder path).
processesPath
Path the PyWPS processes.
title
Title used for your WPS service.
abstract
Description of your WPS service.

Example usage

The following example buildout.cfg installs PyWPS with Anaconda:

[buildout]
parts = pywps

anaconda-home = /home/myself/anaconda

[pywps]
recipe = birdhousebuilder.recipe.pywps
sites = myproject
hostname = localhost
port = 8091

# pywps options
processesPath = ${buildout:directory}/myproject/processes
title = MyProject ...
abstract = MyProject does ...

After installing with Buildout start the PyWPS service with:

$ cd /home/myself/anaconda
$ etc/init.d/supervisord start  # start|stop|restart
$ etc/init.d/nginx start        # start|stop|restart
$ bin/supervisorctl status      # check that pycsw is running
$ less var/log/pywps/myproject.log  # check log file

Open your browser with the following URL:

http://localhost:8091/wps?service=WPS&version=1.0.0&request=GetCapabilities
