Maven的Docker镜像二次打包，再次推送至Harbor中

之所以如此操作，主要原因是，官版的镜像中默认的setting.xml已内置好，不容易修改，
重新二次打包，可以指定我们自己的setting.xml配置，配置自己的私服地址以及解决默认Maven仓库国内下载速度慢的问题

一、创建操作目录

$ cd ~
$ mkdir -p dockerfiles/maven

二、创建 settings.xml 和 Dockerfile

$ cd dockerfiles/maven
$ touch settings.xml Dockerfile

三、编辑 settings.xml 以下供参考

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

编辑settings.xml，主要是对maven的repository与mirror进行配置，内容如下

四、编辑Dockerfile，

来源于 maven:3.6.0-jdk-8-alpine，把编写好的配置settings.xml复制到镜像内即可

FROM maven:3.6.0-jdk-8-alpine
COPY settings.xml /usr/share/maven/ref/

五、构建镜像

$ docker build -t maven:3.5-jdk-8 .

其中maven指的是自定义镜像中的 REPOSITORY
3.5-jdk-8指的是自定义镜像中的 TAG

六、查看镜像

$ docker image ls

七、将自定义的镜像推送到自己的harbor仓库

# 如服务器未登录过，需先使用以下命令登录后再推送
# $ docker login harbor.test.com
$ docker push harbor.test.com/jx-common/maven:3.5-jdk-8

八、使用自定义镜像
