dockermavenplugin 与 dockerfilemavenplugin 对springboot自动打包docker镜像并推送harbor的区别

1.环境说明

harbor在服务器192.168.2.125 未开启https校验；

idea打包使用本地docker打包引擎（docker-desktop（windows安装需要开启hype-v等）），不采用远程2375端口通信；

下面是目录结构

2.老插件

docker-maven-plugin插件1.0.0、1.2.2都会提示Failed to push 192.168.2.125/product-sim2/cybereng-asset:1.0.0, retrying in 10 seconds (1/5).换成1.1.0就正常

　dockerfile文件

#FROM openjdk:8-jre-slim
FROM 192.168.2.125/product-sim2/openjdk/8-jdk-stretch-po-fonts
# 环境变量
ENV WORK_PATH /home/project/fawkes
ENV APP_NAME @project.build.finalName@.@project.packaging@
ENV APP_VERSION @project.version@

EXPOSE 11401

#USER
#USER user:group

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

#ADD

#COPY
COPY $APP_NAME $WORK_PATH/

#LABEL

#ARG

# WORKDIR
WORKDIR $WORK_PATH


RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

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

CMD ["-jar", "-Xmx1024m", "@project.build.finalName@.@project.packaging@"]

#CMD ls -ll

　　老的方式，docker的配置文件在整个项目下，可以访问到@project.build.finalName@.@project.packaging@变量非常方便。

　　命令mvn clean package -DskipTests docker:build  docker:push -s D:\program\apache-maven-3.8.1\conf\settings_zfyz.xml

3.新插件

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <version>1.4.13</version>
    <executions>
        <execution>
            <id>default</id>
            <goals>
                <goal>build</goal>
                <goal>push</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <useMavenSettingsForAuth>
            true
        </useMavenSettingsForAuth>
        <repository>${docker.repository}/${docker.registry.name}/${project.artifactId}</repository>
        <dockerfile>Dockerfile</dockerfile>
        <tag>${project.version}</tag>
        <buildArgs>
            <JAR_FILE>${project.build.finalName}.${project.packaging}</JAR_FILE>
            <JAR_NAME>${project.build.finalName}.${project.packaging}</JAR_NAME>
            <JAR_VERSION>${project.version}</JAR_VERSION>
        </buildArgs>
    </configuration>
</plugin>

dockerfile

#FROM openjdk:8-jre-slim
FROM 192.168.2.125/product-sim2/openjdk/8-jdk-stretch-po-fonts
ARG JAR_NAME
ARG JAR_VERSION
# 环境变量
ENV WORK_PATH /home/project/fawkes
ENV APP_NAME  $JAR_NAME
ENV APP_VERSION $JAR_VERSION
EXPOSE 11401

#USER
#USER user:group

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

#ADD

#COPY
COPY target/$JAR_FILE $WORK_PATH/$JAR_FILE

#LABEL
#STOPSIGNAL
#ARG
#ONBUILD

# WORKDIR
WORKDIR $WORK_PATH


RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN echo 'Asia/Shanghai' >/etc/timezone

# ENTRYPOINT

CMD ["sh", "-c", "java -Djava.security.egd=file:/dev/./urandom -jar -Xmx1024m ${APP_NAME}"]
#CMD ls -ll

　　因为dockerfile文件必须在项目根目录下，无法引用@project.build.finalName@，最后通过docker环境变量+sh命令的方式来传递参数

　　命令mvn clean package -DskipTests dockerfile:build  dockerfile:push -s D:\program\apache-maven-3.8.1\conf\settings_zfyz.xml

最终的docker目录
