基于Alpine Linux构建前端node-web镜像步骤详解

FROM 自己打的镜像:版本

# 安装图形化软件和编译器用于canvas依赖
apk add --update --no-cache make g++ jpeg-dev cairo-dev giflib-dev pango-dev libtool autoconf automake 
# 安装 浏览器 node npm
apk add --update --no-cache chromium nodejs npm

# mac 字体地址 /System/Library/Fonts 其它自己查找
# 镜像字体库地址 /usr/share/fonts/ 不对自己查找下
# 查看运行的镜像 docker ps 找到需要的 CONTAINER ID
docker cp /System/Library/Fonts/ b0cda85d36:/usr/share/fonts/
