1. 手动构建

  • 在jar所在目录编写DockFile

    1. FROM java:8
    2. ENV ARTIFACTID xxxxxx
    3. ENV ARTIFACTVERSION 1.0‐SNAPSHOT
    4. ENV HOME_PATH /home
    5. WORKDIR $HOME_PATH
    6. ADD /$ARTIFACTID‐$ARTIFACTVERSION.jar $HOME_PATH/$ARTIFACTID.jar
    7. ENTRYPOINT ["java", "‐jar", "xxxxxx.jar"]

  • 执行docker build -t xxxxxx:1.0-SNAPSHOT创建镜像

  • 创建容器

    1. docker create ‐‐name xxx ‐t ‐p 8080:8080 ‐e PORT=8080 xxxxxx:1.0‐SNAPSHOT

  • 启动容器

    1. docker start xxx

    2. maven插件自动构建

  • 工程引入docker-maven-plugin

    1. <build>
    2. <!--  -->
    3. <finalName>${project.artifactId}‐${project.version}</finalName>
    4. <plugins>
    5.   <!-- maven打包插件 -->
    6.   <plugin>
    7.     <groupId>org.springframework.boot</groupId>
    8.     <artifactId>spring‐boot‐maven‐plugin</artifactId>
    9.   </plugin>
    10.   <!-- maven构建镜像插件：docker-maven-plugin -->
    11.   <plugin>
    12.     <groupId>com.spotify</groupId>
    13.     <artifactId>docker‐maven‐plugin</artifactId>
    14.     <version>1.0.0</version>
    15.     <!-- docker镜像相关的配置信息 -->
    16.     <configuration>
    17.       <!-- 镜像名，这里用工程名 -->
    18.       <imageName>${project.artifactId}‐${project.version}</imageName>
    19.       <!-- Dockerfile文件所在目录 -->
    20.       <dockerDirectory>${project.basedir}/src/main/resources</dockerDirectory>
    21.       <!-- TAG,这里用工程版本号 -->
    22.       <imageTags>
    23.         <imageTag>${project.version}</imageTag>
    24.       </imageTags> <imageName>${project.artifactId}:${project.version}</imageName>
    26.       <!-- 如下3个配置是持续集成结合Jenkins使用，没有Jenkins可以不用 -->
    27.       <!--<registryUrl>192.168.101.64:5000</registryUrl>-->
    28.       <!--<pushImage>true</pushImage>-->
    29.       <!--<imageName>192.168.101.64:5000/${project.artifactId}:${project.version}</imageName>-->
    31.       <!-- 构建镜像的配置信息 -->
    32.       <resources>
    33.         <resource>
    34.           <targetPath>/</targetPath>
    35.           <directory>${project.build.directory}</directory>
    36.           <include>${project.artifactId}‐${project.version}.jar</include>
    37.         </resource>
    38.       </resources>
    39.     </configuration>
    40.   </plugin>
    41. </plugins>
    42. </build>

  • 在src/main/resource目录编写DockerFile

    FROM java:8
ENV ARTIFACTID xxxxxx
ENV ARTIFACTVERSION 1.0‐SNAPSHOT
ENV HOME_PATH /home
WORKDIR $HOME_PATH
ADD /$ARTIFACTID‐$ARTIFACTVERSION.jar $HOME_PATH/$ARTIFACTID.jar
ENTRYPOINT ["java", "‐jar", "xxxxxx.jar"]

  • 在工程根目录执行

    mvn ‐f pom.xml clean package ‐DskipTests docker:build

  • 创建镜像成功
