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

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@"]

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>

<pushImage>true</pushImage>
<dockerDirectory>target/docker</dockerDirectory>
<imageName>
${docker.repository}/${docker.registry.name}/${project.artifactId}:${project.version}
</imageName>
<imageTags>
<!--docker的tag为项目版本号、latest-->
<imageTag>latest</imageTag>
</imageTags>
<resources>
<rescource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</rescource>
</resources>
</configuration>
</plugin>
</plugins>
</build>
