1.手工方式
1.1.准备Springboot jar项目
将项目打包成jar
1.2.编写Dockerfile
FROM java:8VOLUME /tmpADD elk-web-1.0-SNAPSHOT.jar elk.jarEXPOSE 8080ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/elk.jar"]FROM：表示基础镜像，即运行环境
VOLUME /tmp创建/tmp目录并持久化到Docker数据文件夹，因为Spring Boot使用的内嵌Tomcat容器默认使用/tmp作为工作目录
ADD：拷贝文件并且重命名(ADD elk-web-1.0-SNAPSHOT.jar elk.jar 将应用jar包复制到/elk.jar)
EXPOSE：并不是真正的发布端口，这个只是容器部署人员与建立image的人员之间的交流，即建立image的人员告诉容器布署人员容器应该映射哪个端口给外界
ENTRYPOINT：容器启动时运行的命令，相当于我们在命令行中输入java -jar xxxx.jar，为了缩短 Tomcat 的启动时间，添加java.security.egd的系统属性指向/dev/urandom作为 ENTRYPOINT
1.3.构建容器
[root@VM_0_15_centos elk]# docker build -t elk .Sending build context to Docker daemon 14.43 MBStep 1/5 : FROM java:8Trying to pull repository docker.io/library/java ... 8: Pulling from docker.io/library/java5040bd298390: Pull complete fce5728aad85: Pull complete 76610ec20bf5: Pull complete 60170fec2151: Pull complete e98f73de8f0d: Pull complete 11f7af24ed9c: Pull complete 49e2d6393f32: Pull complete bb9cdec9c7f3: Pull complete Digest: sha256:c1ff613e8ba25833d2e1940da0940c3824f03f802c449f3d1815a66b7f8c0e9dStatus: Downloaded newer image for docker.io/java:8 ---> d23bdf5b1b1bStep 2/5 : VOLUME /tmp ---> Running in 0aec2dc2f98c ---> a52e844f25d4Removing intermediate container 0aec2dc2f98cStep 3/5 : ADD elk-web-1.0-SNAPSHOT.jar elk.jar ---> 3ba2f4fddddaRemoving intermediate container 860a0f748a23Step 4/5 : EXPOSE 8080 ---> Running in 1d3331cc2be6 ---> e9ac33d26ce0Removing intermediate container 1d3331cc2be6Step 5/5 : ENTRYPOINT java -Djava.security.egd=file:/dev/./urandom -jar /elk.jar ---> Running in d354f8ee2af5 ---> 8937e1ade6c7Removing intermediate container d354f8ee2af5Successfully built 8937e1ade6c71.4.运行容器
docker run -di --name 容器名称 -p 8080:8080 镜像名称其中-d表示后台运行容器，这也就自然地解决的Spring Boot不支持后台运行应用程序的问题。
-p 8080:8080表示将容器内部的8080端口映射到宿主机器的8080端口，这样就可以通过宿主机器直接访问应
用。
--name 给容器取一个容易记住的名字方便日后管理。
[root@VM_0_15_centos elk]# docker run -di --name myspringboot -p 8080:8080 8937e1ade6c704d6b2c347950a10c95a039c94a3e51d717e516dd8c3c742e3197687dfcf5523[root@VM_0_15_centos elk]# docker ps -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES04d6b2c34795 8937e1ade6c7 "java -Djava.secur..." 8 seconds ago Up 7 seconds 0.0.0.0:8080->8080/tcp myspringboot[root@VM_0_15_centos elk]# 1.5.查看运行日志

2.Docker远程连接并且使用idea一键部署
2.1.配置docker远程连接端口
首先编辑我们服务器上的docker文件
vim /usr/lib/systemd/system/docker.service修改以ExecStart开头的行（centos 7）：添加
-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock \
修改后保存文件，然后重启docker
systemctl daemon-reloadservice docker restart重启之后测试远程连接是否正常，这里的2375是之前配置的端口
curl elk]# curl >firewall-cmd --zone=public --add-port=2375/tcp --permanent chkconfig iptables off然后打开浏览器测试将之前的localhost修改为你的ip
2.2.使用idea连接到docker
首先下载docker插件，idea2019自带了docker插件。如果没有插件可以选择安装docker插件
然后配置docker地址，在你的File | Settings | Build, Execution, Deployment | Docker
配置完成链接之后，出现了框中的内容即可.
链接成功之后会列出容器和镜像!
配置阿里云镜像加速器：
2.3.docker-maven-plugin 介绍
在我们持续集成过程中，项目工程一般使用 Maven 编译打包，然后生成镜像，通过镜像上线，能够大大提供上线效率，同时能够快速动态扩容，快速回滚，着实很方便。docker-maven-plugin 插件就是为了帮助我们在Maven工程中，通过简单的配置，自动生成镜像并推送到仓库中。
