本人研究docker-compose中间花了大量的时间，网上一大堆，说的都不是很全面，决定贡献出来给大家

前提条件：宿主机安装jdk8，安装docker、安装docker-compose

关于安装docker、docker-compose的文章我前面已经说过了，可以回头再看看。

这里通过演示两个注册中心、一个配置服务：eureka-cluster、eureka-cluster2、config-center

目录结构如下：

1.编写Dockerfile文件

eureka

FROM java:8
# ARG JAR_FILE
# ARG LIB_FILE
ADD lib lib
ADD discovery-eureka-1.0.jar /app.jar
# ADD ${LIB_FILE} /lib
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Duser.timezone=GMT+08"]
CMD ["-Xms512m","-Xmx512m","-jar", "/app.jar","--spring.profiles.active=cluster","--eureka.instance.ipAddress=172.16.11.76","--server.port=8081","--eureka.client.service-url.defaultZone=http://samc:samc@172.16.11.76:8082/eureka/"]

eureka2

FROM java:8
# ARG JAR_FILE
# ARG LIB_FILE
ADD lib lib
ADD discovery-eureka-1.0.jar /app.jar
# ADD ${LIB_FILE} /lib
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Duser.timezone=GMT+08"]
CMD ["-Xms512m","-Xmx512m","-jar", "/app.jar","--spring.profiles.active=cluster","--eureka.instance.ipAddress=172.16.11.76","--server.port=8082","--eureka.client.service-url.defaultZone=http://samc:samc@172.16.11.76:8081/eureka/"]

config-center

FROM java:8
# ARG JAR_FILE
# ARG LIB_FILE
ADD lib lib
ADD config-center-1.0.jar /app.jar
# ADD ${LIB_FILE} /lib
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Duser.timezone=GMT+08"]
CMD ["-Xms512m","-Xmx512m","-jar", "/app.jar","--spring.profiles.active=native","--eureka.instance.ipAddress=172.16.11.76","--server.port=8889","--eureka.client.service-url.defaultZone=http://samc:samc@172.16.11.76:8081/eureka/,http://samc:samc@172.16.11.76:8082/eureka/"]

2.编写docker-compose

version: '3'
services:
  euraka:
    build: /home/cater/spring-java/eureka-cluster
    ports:
     - 8081:8081
    volumes:
     #将项目中的log4j日志目录，映射到宿主机的目录下，格式为  宿主机：容器目录
      - "/application/logs/euraka:/application/logs/business-discovery"
  euraka2:
    build: /home/cater/spring-java/eureka-cluster2
    ports:
      - 8082:8082
   depends_on:
     - euraka
  config-center:
    build: /home/cater/spring-java/config-center
    ports:
      - 8889:8889
    depends_on:
      - euraka
      - euraka2

4 整体结构如下：

5.进入docker-compose.yml所在的目录

运行命令：

docker-compose up -d

即可构建和运行项目
