countries-of-interest-service's Introduction

Countries of interest service

The countries of interest service aims to provide insight into the countries that a specific company is interested in or currently exporting to. The service makes use several data sources including,

Export wins
Data Hub interactions
OMIS orders
Data Hub company profiles

to give the most informed view into a companies intereset in particular countries.

Installation

The backend is built in Python using the Flask framework. Authentication implemented using Hawk and OAUTH2(SSO) authentication. The majority of the functionality is through API calls but a light front end is provided for documentation and dashboarding. This front end uses React and d3 and uses the webpack javascript module bundler.

local Docker installation

Move your environment variables file to $PROJECT_HOME/.env
docker-compose build
docker-compose up

You can configure how docker-compose runs with environment variables,

change the port the application runs on with the PORT environment variable
change the environment file with the ENV_FILE environment variable
e.g. PORT=8000 ENV_FILE=my_envs docker-compose build and again when using docker-compose up

Running postgres in docker now requires a mandatory environment variable called POSTGRES_PASSWORD. This must be added to your .env file.

Config

When using docker-compose

Place environment variables in .env file.

When using host machine

Config variables can be specified in a few ways and are loaded using the following order of priority:

Look for variable in existing System environment variables
If not found in step 1, look for variable in .env (this only works if USE_DOTENV is set to 1)
If not found in step 2, look for variable in local_testing.yml (this only works if TESTING is set to 1)
If not found in step 3, look for variable in local.yml (this only works if TESTING is set to 0)
If not found in step 4, look for variable in default.yml

Testing

Running tests locally

make run_tests_local

to run tests for a specific directory, do,

make run_tests_local TEST=<tests/test_directory>

Running tests the same way as circle ci:

make run_tests
