How to actually setup the Python Component

Hi, I have a question regarding the setup of my client as I can’t really understand what actions do I need to take from the README.md.

I have an Eureka project with the following application.properties

spring.application.name=eureka-service
server.port= 8761
eureka.server.wait-time-in-ms-when-sync-empty=0

eureka.client.register-with-eureka=true
eureka.client.fetch-registry=false

Next, I wanted to attach Zuul Gateway, in order to have a sort of API Gateway. It gets registered without any problem with the following application.properties.

server:
  port: 8073


spring:
  application:
    name: zuul-gateway

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    serviceUrl:
      defaultZone: http://localhost:8761/eureka


zuul:
  ignoredPatterns:
    - /authenticate
    - /delete
    - /refresh
  routes:
    user-service:
      path: /us/**
      url: http://localhost:5000/
      stripPrefix: true

Now comes my problem. I’m trying to register to Eureka (and, then, make it discoverable and callable also from Zuul) a really simple Flask Component, called user-service, defined with just the following lines

from flask import Flask

app = Flask(__name__)


@app.route('/')
def hello_world():
    return 'Hello World!'


if __name__ == '__main__':
    import py_eureka_client.eureka_client as eureka_client

    your_rest_server_port = 5000
    # The flowing code will register your server to eureka server and also start to send heartbeat every 30 seconds
    eureka_client.init(eureka_server="http://localhost:8761",
                       app_name="user-service",
                       instance_port=your_rest_server_port)
    app.run()

When I run all the 3 projects, though, Eureka can’t manage to find the user-service. Even if I try to use init_discovery_client, I’m still getting the same issue.

Could anyone help me on this?

Tried both of configurations but still Eureka won’t see the Flask Component 😦

as well as run_app(sanic_app) is a blocked method, I think you should place it at the end of the method (after eureka_client.init).
