Project Template for distributed Microservices @ Saxsys
Reference Project Template MS, Saxsys
##Service Structure There are 4 Services
- Zuul (API-Gateway) on Port 8080
- Eureka (Service Discovery) on Port 8081
- SearchService on Port 8082
- Subscription on Port 8083
On startup all services register to Eureka. Zuul acts as the API-Gateway and proxies requests to the corresponding services via looking up the service in the Service Discovery.
There are currently 2 important services missing:
- Auth Service (e.g. https://github.com/rohitghatol/spring-boot-microservices)
- Message Broker (https://cloud.spring.io/spring-cloud-stream/)
##How to use & What happens
- Start all services via start script
- Open Eureka Service Discovery Panel under http://localhost:8761/
- Wait that 3 Services appear under "Instances currently registered with Eureka" (Search, Subscription, Zuul) by refreshing the page
- Zuul (running on 8080) is the API Gateway (Config) that routes the search and subscription path to the corresponding services and their REST-Endpoints
- call http://localhost:8080/search/company (The Request runs against Zuul, Zuul requests the services address of the service instance from Eureka and poxies the request to the available service instance)
