1、下载需要的rpm包和从windows下找到需要的中文字体

1.1在http://rpmfind.net/linux/rpm2html/search.php?query=fontconfig(x86-64)地址下载需要的rpm包，分别为一下包：

fontconfig-2.13.0-4.3.el7.x86_64.rpm
freetype-2.8-14.el7.x86_64.rpm
libpng-1.5.13-7.el7_2.x86_64.rpm
ttmkfdir-3.0.9-42.el7.x86_64.rpm

1.2找到字体包

simsun.ttf

2、上传这些包到gitlab

3、通过修改dockerfile文件进行安装
