先說明一下docker須要搭建的微服務的基本狀況：html

項目狀況：一個demo_parent項目，下面三個子模塊：demo_eureka(eureka服務)、demo_article(文章服務）、demo_zuul(網關服務)。
用到的資源有：jdk1.八、mysql5.7。
須要用到的docker容器有：mysql(mysql單獨一個容器）、jdk1.8(article、eureka、zuul三個服務運行在該jdk1.8容器中)

一，用idea新建父項目

File->New->Project->Maven,選擇Project SDK爲jdk8->GroupId:com.demo,ArtifactId:demo_parentjava

修改pom.xml文件，完整以下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </snapshots>
        </pluginRepository>
    </pluginRepositories>
</project>

2、新增demo_eureka模塊,並編寫代碼

右鍵demo_parent->new->Module->Maven,選擇Module SK爲jdk8->ArtifactId:demo_eurekamysql

1.修改pom.xml<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>demo_parent</artifactId>
        <groupId>com.demo</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>demo_eureka</artifactId>


    <dependencies>
        <!-- eureka 服務端依賴 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>
</project>

2.在resources目錄下新增application.yml文件

server:
  port: 7000 #eureka的啓動端口，可自定義
spring:
  application:
    name: demo-eureka #eureka項目名稱，可自定義
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://127.0.0.1:${server.port}/eureka #在IDEA中運行時使用127.0.0.1，部署發佈時，請修改成虛擬機宿主機的ip地址

注：因爲這裏講的是單機部署，因此eureka的register-with-eureka和fetch-registry都設置爲了falseweb

3.新建com.demo.eureka包，並在該包下新建啓動類EurekaApplication

package com.demo.eureka;

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

/**
 * 註冊中心微服務
 */
// 標註爲一個spring boot項目
@SpringBootApplication
// 標註爲Eureka服務端
@EnableEurekaServer
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}
