Raw installation

The following instructions are for a Ubuntu 18.04 LTS.

Installation of node.js and Yarn

G3W-ADMIN use javacript package manager Yarn and Node.js

sudo apt-get install -y nodejs-legacy npm

for install Yarn follow main installation instructions:



If your account is connected to the provider, we’ll try to setup the webhook automatically. If something fails, you can still setup the webhook manually.

Create virtualenv


The following instructions are for python 3.6

Install python pip

sudo apt-get install python3-pip

now we can install virtualenvwrapper

sudo pip3 install virtualenvwrapper

To activate virtuenvwrapper on system login, add follow lines to ‘bashrc’ config file of your user

nano ~/.bashrc
export WORKON_HOME=<path_to_virtualenvs_directory>
source /usr/local/bin/virtualenvwrapper.sh

Virtualenv creation

To create a virtualnenv is sufficent call mkvirtualenv commando follow by the identification name for virtualenv (to use QGIS API into a virtualenv only solution is to give access python system site-packages to it using –system-site-packages option)

mkvirtualenv g3wsuite

Install G3W-SUITE

First step is install dev libraries packages for python module to install with requiriments.txt

sudo apt-get install -y \
    libxml2-dev \
    libxslt-dev \
    postgresql-server-dev-all \
    libgdal-dev \

after is necessary install the correct python module for GDAL library, check your version and install correct module

export CPLUS_INCLUDE_PATH=/usr/include/gdal
export C_INCLUDE_PATH=/usr/include/gdal

pip install GDAL==<installed_version or closest>

Set local_config.py file

G3W-ADMIN is a Django application, and to work is necessary set a config.py file. To start copy local_settings.example.py and set the databse and other:

cd g3w-admin/g3w-admin/base/settings
cp local_settings_example.py local_settings.py

set database, media root and session cookies name:


    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': '<db_name>',
        'USER': '<db_user>',
        'PASSWORD': '<db_user_password>',
        'HOST': '<db_host>',
        'PORT': '<db_port>',


DATASOURCE_PATH = '<static_path_to_gis_data_source>'


MEDIA_ROOT = '<path_to_media_root>'


SESSION_COOKIE_NAME = '<unique_session_id>'

With paver commands

G3W-ADMIN has a series of paver CLI commands to administrate the suite. After prepared environment if sufficient invoce paver install task

paver install


To run the application with paver

paver start

and for stop

paver stop

G3W-ADMIN is a django application so is possibile run app by standard django manage.py commands

./manage.py runserver

Deploy G3W-SUITE

As other Django application, G3W-SUITE can be deployed by its wsgi capabilities. On the web if simple to find tutorial for deploy a Django application.

The simpler way is to use Apache2 as server WEB and its mod_wsgi module.

Alternative solutions are:

Manual installation steps

The preferred installation is by using the paver script as mentioned above, but in case you need to customize the installation process, here are the build and setup steps:

Build static js code

# Install yarn (requires root):
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | \
    tee /etc/apt/sources.list.d/yarn.list
apt-get update && sudo apt install -y yarn
# Back to unprivileged user, from the repository directory, run:
yarn --ignore-engines --ignore-scripts --prod
nodejs -e "try { require('fs').symlinkSync(require('path').resolve('node_modules/@bower_components'), 'g3w-admin/core/static/bower_components', 'junction') } catch (e) { }"

Make sure build components are available in static and collected later

cd g3w-admin/core/static
ln -s "../../../node_modules/@bower_components" bower_components

Install requirements

Possibily within a virtual env:

pip install -r requirements.tx

Django setup

python manage.py collectstatic --noinput
python manage.py migrate --noinput

Install some fixtures for EPSG and other suite options:

for FIXTURE in 'BaseLayer.json' 'G3WGeneralDataSuite.json' 'G3WMapControls.json' 'G3WSpatialRefSys.json'; do
    python manage.py loaddata  core/fixtures/${FIXTURE}

Sync menu tree items (re-run this command in case you installed optional modules and they are not visible in the admin menu tree):

python manage.py sitetree_resync_apps

Continuous integration testing

CI tests are automatically run on CircleCI for the dev branch only.

The Docker compose configuration used in the CI tests is available at docker-compose.yml.

Another configuration for running local tests is provided with docker-compose-local.yml and can also be used for local testing by running:

docker-compose -f docker-compose-local.yml up

The testing image is built from the dependency image and it will run all install and build steps from the local repository.

The dependency image is built from the Dockerfile.deps.
