打包，移包

1. 進入到專案根目錄，通過 mvn clean test package install 生成 jar/war 包。
   

2. 在 target 目錄內，找到打包好的 jar 包 / war 包。複製到 Linux 系統的指定目錄

把 jar包放入對應的目錄內，以下是放好jar包的目錄結構。

編寫 Dockerfile

supershop-service-admin 目錄內的 Dockerfile

[root@localhost supershop]# cat ./supershop-service-admin/Dockerfile 
FROM openjdk:8-jre

MAINTAINER Flying <814110433@qq.com>

RUN mkdir /app

WORKDIR /app

COPY supershop-service-admin.jar /app

ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app/supershop-service-admin.jar"]

EXPOSE 20880 8510
[root@localhost supershop]#

supershop-web-admin 目錄內的 Dockerfile

[root@localhost supershop]# cat ./supershop-web-admin/Dockerfile 
FROM openjdk:8-jre

MAINTAINER Flying <814110433@qq.com>

RUN mkdir /app

WORKDIR /app

COPY supershop-web-admin.jar /app

ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app/supershop-web-admin.jar"]

EXPOSE 8100
[root@localhost supershop]#

supershop-service-redis 目錄內的 Dockerfile

[root@localhost supershop]# cat ./supershop-service-redis/Dockerfile 
FROM openjdk:8-jre

MAINTAINER Flying <814110433@qq.com>

RUN mkdir /app

WORKDIR /app

COPY supershop-service-redis.jar /app

ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app/supershop-service-redis.jar"]

EXPOSE 20882 8512

編寫 docker-compose.yml

根據啟動先後順序和服務型別配置一個或多個 docker-compose.yml 。此處分為 service 和 web 。先啟動 service ，再啟動 web 。

存放 docker-compose.yml 的目錄

[root@localhost docker-compose]# tree

├── service
│   └── docker-compose.yml
└── web
    └── docker-compose.yml

2 directories, 2 files
[root@localhost docker-compose]# pwd
/root/supershop/docker-compose
[root@localhost docker-compose]# ls
service  web		
[root@localhost docker-compose]# 

service 的 docker-compose 內容

[root@localhost docker-compose]# cd service/
[root@localhost service]# 
[root@localhost service]# ls

啟動

先進入 service 目錄： docker-compose build && docker-compose up -d
再進入 web 目錄： docker-compose build && docker-compose up -d
