springboot 利用 docker-maven插件生成docker镜像并推送到镜像仓库

springboot 利用 docker-maven插件生成docker镜像并推送到镜像仓库

一、环境配置
java、maven 、docker 安装及环境变量配置
    1. maven配置文件修改

    <server>
      <id>docker-aliyun</id>
      <username>私仓账号</username>
      <password>私仓密码</password>
      <configuration>
            <email>邮箱</email>
      </configuration>
    </server>

    2.docker 添加环境变量
    配置DOCKER_HOST环境变量：tcp://localhost:2375 打开daemon 2375访问权限（windows docker >> settings >> General）

二、添加Dockerfile文件及修改maven编译配置

1. 添加Dockerfile

FROM java:8

MAINTAINER ziyun "wlcloudy@163.com"

# 环境变量
ENV WORK_PATH /home/project/eureka-server
ENV APP_NAME @project.build.finalName@.@project.packaging@
ENV APP_VERSION @project.version@

EXPOSE 5555

#VOLUME
VOLUME ["/home/project", "/tmp/data"]

#COPY
COPY $APP_NAME $WORK_PATH/

# WORKDIR
WORKDIR $WORK_PATH

# ENTRYPOINT
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom"]

# CMD
CMD ["-jar", "@project.build.finalName@.@project.packaging@"]

1. 修改maven打包配置信息

<!-- 添加镜像仓库 -->
<properties>
        <docker.repository>仓库地址</docker.repository>
        <docker.registry.name>仓库名（即阿里云仓库命名空间名称）</docker.registry.name>
</properties>

<build>
        <finalName>EurekaServer</finalName>
        <!-- Dockerfile文件路径配置 -->
        <resources>
            <resource>
                <directory>src/main/docker</directory>
                <filtering>true</filtering>
                <includes>
                    <include>**/Dockerfile</include>
                </includes>
                <targetPath>../docker</targetPath>
            </resource>
        </resources>
        <plugins>
            <!-- 打包Docker -->

                </executions>
                <configuration>
                    <!-- 私有仓库配置，需要settings.xml文件配合serverId对应的服务地址 -->
                    <serverId>docker-aliyun</serverId>

                    <imageTags>
                        <!--docker的tag为项目版本号、latest-->
