Question

我正在使用postgres和一些其他我项目的基本软件包在CentOS 7上为开发环境构建映像。但是最终大小约为900MB，我什至删除了一些在构建过程后将不再使用的软件包。

# Here I copy some files and stuff related to the database from my host machine to the container, they all combined have 4MB (in my local machine)

USER postgres 

CMD ["/usr/pgsql-9.6/bin/postgres", "-D", "/var/lib/pgsql/9.6/data"]

我看到了一些其他的postgres图片，其中大多数都小于100MB。我该怎么做才能减小此尺寸？

码头工人-为什么我的码头工人图像太大？
