Interact with our microservices architecture

This microservice works on port 5001.

First setup

Export the address and the port of the data-service microservice, the default is 127.0.0.1:5002.

A smart way to do this is to create a file variables.sh in the project root, as follows.

#!/bin/bash
export DATA_SERVICE="127.0.0.1:5002"

You can load the variables with source variables.sh.

Install for development

pip install -r requirements.txt
pip install pytest pytest-cov
python setup.py develop

Install for production

pip install -r requirements.txt
python setup.py install

Run the microservice

Terminal #1

Start the data-service microservice.

Terminal #2

1. Load environment variables:
   source variables.sh

2. Start with:
   python flaskapp/app.py

Docker

A Docker Image is available on the public Docker Hub registry. You can run it with the command below.

• Run the data-service container
• Run mail-service with docker run -d --name flask-app -e DATA_SERVICE="data-service:5002" --link data-service:data-service ytbeepbeep/flask-app

Important note: if the data-service container is running on another Docker installation, replace data-service with the host, as follows: -e DATA_SERVICE="<myhost-name-or-address>:5002"

Locally

You can also build your own image from this repository.

• Build with docker build -t ytbeepbeep/flask-app .
• Run as usually, with the commands specified above
