maven构建docker镜像推送至私有docker仓库

1、创建私有docker仓库

2、在maven项目中，添加【Dockerfile】文件，【Dockerfile】文件一般放置在项目main/docker目录下

FROM openjdk:8

MAINTAINER Sunny 914204907@qq.com

VOLUME /tmp

ADD springboot-test.jar app.jar

RUN bash -c 'touch /app.jar'

RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone

EXPOSE 18889

ENTRYPOINT ["java", "-jar", "app.jar"]

3、修改maven的setting文件，添加docker私有仓库的账号密码

<servers>    
        <server>
            <id>docker-hub</id>
            <username>docker-user</username>
            <password>123456</password>
            <configuration>
                <email>914204907@qq.com</email>
            </configuration>
        </server>
    </servers>

4、修改pom文件

<build>
        <finalName>springboot-test</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!-- Docker -->
            <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 ，就会自动执行mvn docker:build -->
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal> <!--build命令，相当于docker的build命令 会读取Dockerfile来构件docker镜像-->
                        </goals>
                    </execution>
                    <execution>
                        <id>image-tag</id>
                        <phase>package</phase>
                        <goals>
                            <goal>tag</goal>      <!--tag命令，相当于docker的tag命令-->
                        </goals>
                        <configuration>
                            <image>cxw/${project.build.finalName}</image>   <!--镜像名-->
                            <newName>192.168.2.216:5000/cxw/${project.build.finalName}</newName>   <!--打的标签名-->
                        </configuration>
                    </execution>
                    <execution>
                        <id>package-push</id>
                        <phase>package</phase>
                        <goals>
                            <goal>push</goal>    <!--相当于docker的push命令！！！ 这里会去maven的setting文件中根据configuration/serverId标签的id，读取到docker私有仓库的用户名和密码-->
                        </goals>
                        <configuration>
                            <imageName>192.168.2.216:5000/cxw/${project.build.finalName}</imageName>  <!--要push的镜像名-->
                        </configuration>
                    </execution>
                </executions>
                <configuration>
                    <!-- 指定生成的镜像名 -->
                    <imageName>cxw/${project.build.finalName}</imageName>
                    <!-- 指定标签 -->
                    <imageTags>
                        <imageTag>${project.version}</imageTag>
                    </imageTags>
                    <!-- 指定 Dockerfile 路径 -->
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <!-- 指定远程 docker api地址 -->
                    <dockerHost>http://192.168.2.216:2375</dockerHost>
                    <authConfig>
                        <username>docker-user</username>
                        <username>123456</username>
                    </authConfig>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <!-- jar包所在的路径此处配置的对应target目录 -->
                            <directory>${project.build.directory}</directory>
                            <!-- 需要包含的jar包,这里对应的是Dockerfile中添加的文件名　-->
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <serverId>docker-hub</serverId>   <!--mvn setting.xml配置的那个id-->
                </configuration>
            </plugin>
        </plugins>
    </build>

 

 

手动推送docker镜像至私有仓库的方式

1、给镜像打tag

docker image ls

session-web:latest

docker tag session-web:latest 127.0.0.1:5000/session-web:latest

2、推送镜像

docker push 127.0.0.1:5000/session-web:latest
