Tutorial 2: How To contribute, Create your own service

• First, you must create a file with the name of your service inside of pyms.flask.service, for example, "myawesomesrv":

pyms/flask/services/myawesomesrv.py

from pyms.flask.services.driver import DriverService


class Service(DriverService):
    service = "myawesomesrv"
    default_values = {
        "myvalue": 0,
        "myvalue2": 1
    }

• Now, you can configure your service from config.yml

pyms:
  config:
    myawesomesrv:
      myvalue: 5

• Your service will be instanced inside the ms object in flask.current_app object. For example, with the last config, you could print the folowing code:

from flask import jsonify, current_app

from pyms.flask.app import Microservice

ms = Microservice(service="my-minimal-microservice", path=__file__)
app = ms.create_app()


@app.route("/")
def example():
    return jsonify({
        "myvalue": current_app.ms.myawesomesrv.myvalue, 
        "myvalue2": current_app.ms.myawesomesrv.myvalue2
    })


if __name__ == '__main__':
    app.run()

This would be the output in http://localhost:5000/:

{"myvalue": 5, "myvalue2": 1}
