Spring Cloud Zipkin Tracing

Examples of microservice instrastructures

This project contains several examples of microservice infrastructures implemented with Spring Boot and Spring Cloud projects. The aim of each project is to provide an end to end example, being able to deploy it without too much hassle.

History

- Config Server: use local or git
- Integrate Eureka Service
- Integrate Gateway Service
- Integrate Zipkin
- Apply docker-compose

Overview

• config-service: Load all configs for services via port 8888

• eureka-service: Run service via port 8761

• rating-service: Run service via port 5000

• student-service: Run service via port 7000

• zipkin-server: Run service via port 9411

• zipkin-ui-server

• gateway-service Run service via port 8090

Note: In the example, I don't use config-service but this is a good way. Therefore, I keep it in the example. I hope I will apply it in the project.

Notes: We can change port(9412) Check README.md in zipkin-ui-server

-zipkin.web.port=:9412

If you could not see all services in zipkin UI, please run http://localhost:5000 and http://localhost:7000 many times. The zipkin web will reload all services.

Config Server

Run dockerfile, it will get config-repo on https://github.com/nhatthai/config-repo
