Vehicle Locator Application Assets

This repo contains modules for Vehicle Locator application template for a customer workshop

vehicle-location-client houses the consumer end of the application

vehicle-location-service houses the server piece which houses the smarts to track vehicle locations using GPS and incoming sensor data

service-registry houses the eureka server piece which keeps the registry of variuous modules

config-server retains all the configuration pieces

  1. Create Service Registry in Spring Cloud Services on PCF
    cf create-service p-service-registry standard vehicle-service-registry

  2. Create Circuit Breaker Dashboard also in SCS on PCF
    cf create-service p-circuit-breaker-dashboard standard vehicle-circuit-breaker

  3. First, demonstrate the Spring Cloud Contracts piece by going to vehicle-location-service and demoing the groovy contract templates.
    Use mvn clean package to create tests and stubs, and then mvn install to install the maven repository for consumer testing

  4. Then, change over to vehicle-location-client and run the stubbed out Wiremock service functionality to test consumer in isolation. Once, the consumer piece is finished, make sure to uncomment the following pieces to run in full-online mode (i.e. location service is running and accessible)
