Contents

Prerequisites

  1. Install Docker
  1. Install Docker Compose

Installing the application

  1. Get the source code:

    $ git clone https://github.com/eea/art17-consultation.git
$ cd art17-consultation

  2. Customize env files:

    $ cp docker/app.env.example docker/app.env
$ cp docker/db.env.example docker/db.env

  3. Customize docker orchestration:

    $ cp docker-compose.override.yml.example docker-compose.override.yml

  4. Start stack, all services should be "Up"

    $ docker-compose up -d
$ docker-compose ps

  • Create your user and assign admin role to it:

    # for local user
./manage.py user create -e user_email -i user_id -p <password>
# for Eionet user
./manage.py user create -i user_id --ldap
# make it admin
./manage.py role add -u user_id -r admin

Configuration

Details about configurable settings can be found in settings.py.example.

Configuring the LDAP SERVER

The authentication is provided by a LDAP SERVER. Add the following configuration variables to the app, using the correct URLs for the LDAP server:

EEA_LDAP_SERVER=ldaps://ldap.example.com EEA_LDAP_PORT=389

Data Import

Initially the application's database is empty. We need to import data from a dump (the old 2006 app's database or the new reporting data). First we need to load this dump into a separate database:

mysql -e 'create database art17_2006 CHARACTER SET utf8 COLLATE utf8_general_ci;'
mysql art17_2006 < art17_2006.sql

Then we can import this data into our app's database. Make sure to specify the right schema version, in this case '2006':

./manage.py dataset import -d import-from-2006 -i 'mysql://user:pass@localhost/art17_2006' -s 2006

An optional argument -f (fallback) exists. When there are no records to import in a table, it copies the entire table from the specified dataset.

Upgrading the application

  1. Get the latest version of source code:

    $ cd art17-consultation
$ git pull origin master

  2. Update the application stack, all services should be "Up"

    $ docker-compose up -d
$ docker-compose ps

Development hints

Requirements

User requirements-dev.txt instead of requirements-dep.text:

pip install -r requirements-dev.txt

Configure deploy

  • copy fabfile/env.ini.example to fabfile/env.ini
  • configure staging and production settings
  • run fab staging deploy or fab production deploy

Running unit tests

Simply run py.test testsuite, it will find and run the tests. For a bit of speedup you can install pytest-xdist and run tests in parallel, py.test testsuite -n 4.

Factsheet generator

Printouts work using wkhtmltopdf 0.12.1. Using another version may cause problems in rendering pdfs.

If you don't have this version installed, add it to your virtualenv.

  1. Go to http://sourceforge.net/projects/wkhtmltopdf/files/0.12.1/ and select the build corresponding with your system. Copy the direct link into your clipboard

  2. Install it locally in your virtualenv

    • For RedHat-based systems in production:

      wget $PASTE_URL_COPIED_AT_STEP_1
# $PACKAGE is the file downloaded with wget
sudo rpm -i --prefix=/var/local/wkhtmltox-0.12.1 $PACKAGE.rpm
# If the command fails because the file is already installed
# copy `wkhtmltopdf` from the installation directory and skip
# the next command
cp /var/local/wkhtmltox-0.12.1/bin/wkhmtltopdf sandbox/bin/

    • For RedHat-based development systems:

      # If you don't work on projects that require other versions
# Install this version globally
wget $PASTE_URL_COPIED_AT_STEP_1
sudo rpm -i $PACKAGE.rpm

    • For Debian based systems:

      wget $PASTE_URL_COPIED_AT_STEP_1
dpkg-deb -x wkhtmltox-0.12.1_<your_distro>.deb sandbox
cp sandbox/usr/local/bin/wkhtmltopdf sandbox/bin

Development instructions using Docker

Make sure you set DEBUG=True in app.env to reload the changes.

  • Start stack, all services should be "Up"

    $ docker-compose up -d
$ docker-compose ps

  • Check application logs:

    $ docker-compose app

  • When the image is modified you should update the stack:

    $ docker-compose up -d --build

  • Delete the containers and the volumes with:

    $ docker-compose down -v

Debugging

  • Please make sure that DEBUG=True in app.env file.

  • Update docker-compose.override.yml file app section with the following so that docker-entrypoint.sh is not executed:

    entrypoint: ["/usr/bin/tail", "-f", "/dev/null"]

  • Attach to docker container and start the server in debug mode:

    $ docker exec -it art17consultation_app_1 bash
# ./manage.py runserver -t 0.0.0.0 -p 5000

  • See it in action: http://localhost:5000
