Samples

  • five microservices that are called each other
  • eureka server (or you may use consul with small changes) (http://{you_docker_machine_host}:8761/)
  • gateway server with hystrix dashboard (see http://{you_docker_machine_host}:9000/hystrix/) and service routing
  • ops server with open zipking tracing through sleuth (http://{you_docker_machine_host}:9411/)
  • turbine server for colleting hystrix data from all services through rabbit-mq

Build, run, rebuild

build app: ./gradlew build

build image: ./gradlew dockerBuild

run all: ./run up -d

rebuild: ./rebuild-{sub-project-name}

rebuild script redeploy app automatically

example:

./gradlew build && ./run up -d && ./rebuild-rent-service

Step0

  • do nothing. Just launch ./rebuild-all ./run up

Step1

  • add @EnableDiscoveryClient to rent-service

  • add eureka client configuration to it

  • fix docker-compose.yml with env, links and dependsOn properties

  • then launch again and test /rent method

Step2

  • add gateway

Step 3

  • add @EnableHystrix annotation to rent-service

  • add dependency with hystrix-starter

  • add feign.hystrix.enabled to application.yml

  • then rebuild and check hystrix-dashboard at gateway-server

Step 4

  • add hystrix-stream starter and stream-rabbit to rent-service
  • add rabbitmq endpoint (spring properties) to rent-service in docker-compose.yml

Step 5

  • add sleuth starter, zipkin starter and sleuth-zipkin start to rent-service
  • add zipkin base url to rent-service in docker-compose.yml
