mvn package  # 打包 war/jar ，并打包 docker image 
docker push register-domain-name/group-name/project-name:tag-name    # push image
## mvn deploy  # 需要提前配置 install 

注意：

1. 镜像名称要全部小写，不然会报错 I/O exception https://github.com/spotify/dockerfile-maven/issues/123
2. 需要在项目中准备Dockfile

      </plugin>

jar 包自定义 entrypoint

 <entrypoint>
  <arg>/bin/sh</arg>
  <arg>-c</arg>
 <arg>java ${JAVA_OPTS} -cp /app/resources/:/app/classes/:/app/libs/* 
   com.example.JibDemoApplication</arg>
</entrypoint>

以上配置中， <phase>install</phase> ，只有在 mvn install 时才进行docker 镜像打包及上传。 mvn package 只进行war/jar 的打包。

#mvn compile jib:dockerBuild     # 打包本地镜像
#mvn clean compile package jib:dockerBuild        # 打包本地镜像并上传到仓库
 mvn install  # 打包本地镜像并上传到仓库
