Microservice Patterns and Best Practices

Writing the server access

The app.py file is responsible for an instance of Flask. Just like any Python file, we will start by importing the dependencies. Soon after, we have the declaration of the instance of Flask, the access settings, the statement of routes, and the command to run the server:

 
import os 
from flask import Flask 
 
from views import news 
 
# instantiate the app 
app = Flask(__name__) 
 
# set config 
app_settings = os.getenv('APP_SETTINGS') 
app.config.from_object(app_settings) 
 
# register blueprints 
app.register_blueprint(news) 
 
if __name__ == '__main__': 
    app.run(host='0.0.0.0', port=5000)
