SpringBoot 远程打包Docker镜像

运行环境

远程环境 CentOS Linux 7
本地环境 Windows 10
Docker版本 1.13.1, build 774336d/1.13.1

开启docker远程连接

修改配置

vim /usr/lib/systemd/system/docker.service

在ExecStart后面 添加一行（表示启动2375端口 用于监听远程操作）

-H tcp://0.0.0.0:2375  -H unix:///var/run/docker.sock \

docker.service修改后部分展示

          $REGISTRIES
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=1048576
LimitNPROC=1048576

重新加载配置文件

systemctl daemon-reload

重启服务

systemctl restart docker.service 

端口查看

netstat -nptl 

curl看是否生效

curl http://127.0.0.1:2375/info

修改pom.xml配置

   	   <plugin>
   			<groupId>org.springframework.boot</groupId>
   			<artifactId>spring-boot-maven-plugin</artifactId>
   		</plugin>

创建Dockerfile

FROM java:8

MAINTAINER [e-mail]

WORKDIR /

ARG JAR_FILE

ADD ${JAR_FILE} app.jar

EXPOSE 58035

ENV TZ=Asia/Shanghai

RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

ENTRYPOINT ["sh" ,"-c","java -Djava.security.egd=file:/dev/./urandom -jar app.jar"]

将Dockerfile放到项目根目录下

Eclipse构建

项目右键-> Run As -> Maven Build…
填写maven命令
clean package dockerfile:build

添加DOCKER_HOST

点击Run开始构建
