关于构建图像最具挑战性的事情之一是保持图像的大小。Dockerfile中的每条指令都会为图像添加一个图层,并且您需要记住在移动到下一图层之前清理不需要的任何工件。为了编写一个非常高效的Dockerfile,传统上需要使用shell技巧和其他逻辑来尽可能地减小图层,并确保每个图层都具有它从上一图层需要的构件,而不是其他任何东西。
The AppleScript code below will quit Mail, vacuum the SQLite index, then re-open Mail. On a large email database that hasn't been optimized for a while, this can provide significant improvements in responsiveness and speed. (* Speed up Mail.app by vacuuming the Envelope Index ...
