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