Aither shows an approach how to bootstrap a microservice system in Node.js with Hemera 5 and docker. You can scale your worker in seconds and because we use NATS as “nervous system" for our distributed system we do not have to worry about service-discovery or load-balancing of hemera-services. We use traefik to load-balancing the api-gateway.

This configuration will setup:

  • Hapi http server which act as api-gateway to the Hemera services.
  • Microservice which is responsible to add two numbers.
  • NATS server the underlying messaging system for Hemera.
  • Jaeger CNCF Jaeger, a Distributed Tracing System.
  • Natsboard dashboard to monitoring your NATS system in realtime.
  • Traefik modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
  • Redis in memory cache for Hemera.

Versions

  • Hapi 17
  • Hemera 5

Architecture

Getting started

  • Running the system docker-compose up
  • Start a request against load balancer OPEN
  • Scale the system docker-compose scale math-service=5 api=2

Dashboards

Run load test

npm install -g artillery
artillery run loadtest.yml

Print the html artillery report with artillery report <report.json>
