This is a basic approach of building a Microservice on top of Flask, with some useful packages like:

• Flask
• Flask-Injector
• Connexion

Requirements

We are going to build a microservice to index rooms information coming from another service (crawler). This service will be responsible for indexing the information into Elasticsearch.

The indexing will be a process of:

• Validate and sanitize the data
• Get some metadata from the room information like geolocalization
• Upload the given images URL to Amazon S3
• Send an event to RabbitMQ every time a new room has been indexed serializing the payload with Avro.

Endpoints:

Method	URI	Description	Status
POST	/room	it will receive the room payload, and it will proceed to index it	Development
PATCH	/room/{id}	this PATCH method will allow us to make changes on the indexed item	Not started
DELETE	/room/{id}	this method will remove the room from the index	Not started
GET	/room/{id}	this method will return the room data for a given room id	Not started
GET	/health-check	This endpoint retuns the state of the service	Not started

Running the environment

You need to have Docker installed in your machine, after that, just run this command docker-compose build && docker-compose up -d.
