docker-maven-plugin插件設置Docker的buildArgs

docker-maven-plugin是spotify出品的一款針對spring boot項目的docker插件，可將spring boot項目打包到docker鏡像中。

如果在編譯docker鏡像時需要設置build arg，只需要在maven的配置文件pom.xml中，configuration下增加buildArgs。標簽的key和值對應build arg的key和值，如下所示，docker鏡像編譯過程中，會有一個build arg名為ARG_TIME_ZONE，而其值則為OS的環境變量TIME_ZONE。
