創建Docker目錄
新建docker-compose.yml和Dockerfile

創建src/main/java目錄
新建com.funtl.cbj.eureka包
新建EurekaApplication啓動類

package com.funtl.cbj.eureka;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}

在main目錄下新建resources
新建bootstrap.yml

spring:
  cloud:
    config:
      uri: http://localhost:8888
      name: cbj-eureka
      label: master
      profile: dev

bootstrap-test.yml

spring:
  cloud:
    config:
      uri: http://192.168.0.27:8888
      name: cbj-eureka
      label: master
      profile: test

bootstrap-prod.yml

spring:
  cloud:
    config:
      uri: http://192.168.0.27:8888
