1. 手工形式
1.1. 筹备 Springboot jar 我的项目
] 将我的项目打包成 jar
1.2. 编写 Dockerfile
FROM java:8
VOLUME /tmp
ADD elk-web-1.0-SNAPSHOT.jar elk.jar
EXPOSE 8080
ENTRYPOINT [“java”,”-Djava.security.egd=file:/dev/./urandom”,”-jar”,”/elk.jar”]
FROM：示意根底镜像，即运行环境 VOLUME /tmp 创立 /tmp 目录并长久化到 Docker 数据文件夹，因为 Spring Boot 应用的内嵌 Tomcat 容器默认应用 /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 将利用 jar 包复制到 /elk.jar) EXPOSE：并不是真正的公布端口，这个只是容器部署人员与建设 image 的人员之间的交换，即建设 image 的人员通知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，相当于咱们在命令行中输出 java -jar xxxx.jar，为了缩短 Tomcat 的启动工夫，增加 java.security.egd 的零碎属性指向 /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 MB

1.4. 运行容器
docker run -di –name 容器名称 -p 8080:8080 镜像名称
其中 - d 示意后盾运行容器，这也就天然地解决的 Spring Boot 不反对后盾运行应用程序的问题。-p 8080:8080 示意将容器外部的 8080 端口映射到宿主机器的 8080 端口，这样就能够通过宿主机器间接拜访应 用。–name 给容器取一个容易记住的名字不便日后治理。
[root@VM_0_15_centos elk]# docker run -di –name myspringboot -p 8080:8080 8937e1ade6c7

1.6. 拜访测试
2.Docker 近程连贯并且应用 idea 一键部署
2.1. 配置 docker 近程连贯端口
首先编辑咱们服务器上的 docker 文件
vim /usr/lib/systemd/system/docker.service
批改以 ExecStart 结尾的行（centos 7）：增加
-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
批改后保留文件，而后重启 docker
systemctl daemon-reload
service docker restart
重启之后测试近程连贯是否失常，这里的 2375 是之前配置的端口
curl http://localhost:2375/version
看到返回信息基本上就没有问题了
[root@VM_0_15_centos elk]# curl http://localhost:2375/version
{“Version”:”1.13.1″,”ApiVersion”:”1.26″,”MinAPIVersion”:”1.12″,”GitCommit”:”7f2769b/1.13.1″,”GoVersion”:”go1.10.3″,”Os”:”linux”,”Arch”:”amd64″,”KernelVersion”:”3.10.0-957.21.3.el7.x86_64″,”BuildTime”:”2019-09-15T14:06:47.565778468+00:00″,”PkgVersion”:”docker-1.13.1-103.git7f2769b.el7.centos.x86_64″}
而后开启端口，或者敞开防火墙，二者选其一即可
firewall-cmd –zone=public –add-port=2375/tcp –permanent
chkconfig iptables off
而后关上浏览器测试将之前的 localhost 批改为你的 ip
2.2. 应用 idea 连贯到 docker
首先下载 docker 插件，idea2019 自带了 docker 插件。如果没有插件能够抉择装置 docker 插件
而后配置 docker 地址，在你的 File | Settings | Build, Execution, Deployment | Docker 配置实现链接之后，呈现了框中的内容即可. 链接胜利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
在咱们继续集成过程中，我的项目工程个别应用 Maven 编译打包，而后生成镜像，通过镜像上线，可能大大提供上线效率，同时可能疾速动静扩容，疾速回滚，着实很不便。docker-maven-plugin 插件就是为了帮忙咱们在 Maven 工程中，通过简略的配置，主动生成镜像并推送到仓库中。
pom.xml:
<build>
<finalName>${project.artifactId}</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
</configuration>
</plugin>
<!– 跳过单元测试 –>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
<!– 应用 docker-maven-plugin 插件 –>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>1.0.0</version>
<!– 将插件绑定在某个 phase 执行 –>
<executions>
<execution>
<id>build-image</id>
<!– 用户只需执行 mvn package，就会主动执行 mvn docker:build–>
<phase>package</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
</executions>
<configuration>
<!– 指定生成的镜像名 –>
<imageName>bruceliu/${project.artifactId}</imageName>
<!– 指定标签 –>
<imageTags>
<imageTag>latest</imageTag>
</imageTags>
<!– 指定根底镜像 jdk1.8–>
<baseImage>java</baseImage>
<!– 镜像制作人自己信息 –>
<maintainer>bruceliu@email.com</maintainer>
<!– 切换到 ROOT 目录 –>
<workdir>/ROOT</workdir>
<cmd>[“java”, “-version”]</cmd>
<entryPoint>[“java”, “-jar”, “/${project.build.finalName}.jar”]</entryPoint>
<!– 指定近程 docker api 地址 –>
<dockerHost>http://122.51.50.249:2375</dockerHost>
<!– 这里是复制 jar 包到 docker 容器指定目录配置 –>
<resources>
<resource>
<targetPath>/</targetPath>
<!–jar 包所在的门路 此处配置的 即对应 target 目录 –>
<directory>${project.build.directory}</directory>
<!– 用于指定须要复制的文件 须要蕴含的 jar 包，这里对应的是 Dockerfile 中增加的文件名 –>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
</plugins>
</build>
