SpringCloud

1. 首先在 Amnibus-CaaS 平台上使用 SpringCloud-Eureka 模板创建服务发现与注册组件 Eureka，Eureka Route HostName 建议按 eureka.${apps_dns_domain} 规则填写。

2. 测试 Eureka 服务是否正常：

   $ curl https://eureka.${apps_dns_domain}/health
   {"description":"Composite Discovery Client","status":"UP"}

3. 创建服务提供者 microservice-provider-user

   eureka.client.serviceUrl.defaultZone 需要对应已经创建好的 Eureka 服务，即 https://eureka.${apps_dns_domain}/eureka

   $ oc apply -f microservice_provider_user_configmap.yaml
   $ oc apply -f microservice_provider_user_deployment.yaml
   $ oc scale deployment microservice-provider-user-deployment --replicas=3

4. 创建服务消费者 microservice-consumer-movie

   同样 eureka.client.serviceUrl.defaultZone 需要对应已经创建好的 Eureka 服务，即 https://eureka.${apps_dns_domain}/eureka

   $ oc apply -f microservice_consumer_movie_configmap.yaml
   $ oc apply -f microservice_consumer_movie_deployment.yaml
   $ oc apply -f microservice_consumer_movie_service.yaml

5. 测试消费者是否成功从 Eureka 获取服务提供者

   $ curl http://microservice-consumer-movie.default.svc.cluster.local/user/1
   {"id":1,"username":"account1","name":"张三","age":20,"balance":100.00}
   $ curl http://microservice-consumer-movie.default.svc.cluster.local/user/2
   {"id":2,"username":"account2","name":"李四","age":28,"balance":180.00}
   $ curl http://microservice-consumer-movie.default.svc.cluster.local/user/3
   {"id":3,"username":"account3","name":"王五","age":32,"balance":280.00}
