##### 手动部署 #####

`根据已有的jar生成镜像 新建文件夹dockerfile,将项目的jar移入，接下来编写Dockerfile文件内容如下(简单实例):`

FROM java:8
    VOLUME /tmp
    ADD my-blog.jar app.jar
    RUN bash -c 'touch /app.jar'
    EXPOSE 9000
    ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

`将Dockerfile文件和项目jar放在一起，然后执行(需要docker环境)`

docker build -t="myblog:v1.0" /dockerfile
    (/dockerfile 为dockerfile所在的路径)

##### 插件部署(docker-maven-plugin) #####

<build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
                
                <plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>1.0.0</version>
                    <configuration>
                        
                        
                        <imageName>my-blog</imageName>
                        <imageTags>
                            <imageTag>v4</imageTag>
                        </imageTags>
                        
                        <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
                        <resources>
                            <resource>
                                <targetPath>/</targetPath>
                                <directory>${project.build.directory}</directory>
                                <include>${project.build.finalName}.jar</include>
                            </resource>
                        </resources>
                    </configuration>
                </plugin>
            </plugins>
            <finalName>my-blog</finalName>
        </build>

`其中<dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>Dockerfile的路径 Dockerfile文件的内容如下:`

#第一行必须指令基于的基础镜像
    FROM java:8
    #指定维护者的基本信息
    MAINTAINER jishanwang123@163.com
    VOLUME /tmp
    ADD my-blog.jar app.jar
    RUN bash -c 'touch /app.jar'
    EXPOSE 8080
    ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

`以上准备完毕，在项目的跟目录执行(需要docker环境)`

> mvn clean package docker:build

##### 插件部署(推送到阿里云镜像库) #####

在maven的settings.xml中添加

<server>
            
          <id>docker-aliyun</id>
          
          <username>12345678@qq.com</username>
          
          <password>abcdef</password>
          <configuration>
                
                <email>12345678@qq.com</email>
          </configuration>
        </server>

在pom.xml中添加吐下代码

<properties>
            <docker.repostory>registry.cn-beijing.aliyuncs.com</docker.repostory>
            <docker.registry.name>wangjishan</docker.registry.name>
            <docker.image.prefix>my-blog</docker.image.prefix>
            <docker.image.version>0.1</docker.image.version>
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
            <java.version>1.8</java.version>
        </properties>

<build>
            <plugins>
                
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
                
                <plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>1.0.0</version>
                    
                    <configuration>
                        
                        <imageName>${docker.repostory}/${docker.registry.name}/${docker.image.prefix}:${docker.image.version}</imageName>
                        
                        <imageTags>
                            <imageTag>v1</imageTag>
                        </imageTags>
                        
                        <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
                        <resources>
                            <resource>
                                <targetPath>/</targetPath>
                                <directory>${project.build.directory}</directory>
                                <include>${project.build.finalName}.jar</include>
                            </resource>
                        </resources>
                        <serverId>docker-aliyun</serverId>
                        <registryUrl>${docker.repostory}</registryUrl>
                        <pushImage>true</pushImage>
                    </configuration>
                </plugin>
            </plugins>
            <finalName>my-blog</finalName>
        </build>

`添加完后执行，开始构建 mvn -f pom_ali.xml clean package -DskipTests docker:build`

##### 镜像的运行 #####

docker run -v /xxa:/xxb -d -p 22061:22061 imagename:tag

`解释： (1) -v 挂载目录 /xxa 宿主机的目录 /xxb容器的目录(Dockerfile中的挂载点) (2) imagename 镜像名称 tag镜像tag`
