将试着做出最小的 docker 容器给 Gaea 进行测试 (Provide a smaller size of container for Gaea usage)

小米您好

我试着做出最小的数据库容器给 Gaea 进行测试，想辨法把容器的大小压到比官方容器还要小，目前找到关键所在
(I am struggling with creating a smaller database container for Gaea usage. There is a critical point.)

关键在官方把 mariadb 的 lib 全部清除，也是这个原因，我之前无法做出比官方容器更小的镜像
(Official MariaDB docker removes all files inside /var/lib/mysql. It was the main reason I had not made the image smaller than the Official before.)

大家会使用官方镜像去做为基底，所以多多少少，为了大家方便，官方镜像无法做到太小
(People use the official docker as a base image. It will avoid the official docker being too tiny to have trouble being the base image.)

我是觉得为了测试方便和效率，有必要把容器做到尽量小
(It is necessary to get a smaller image size to get more efficiency.)

这个容器小很多，还要在改良，执行速度要加强
This container is smaller. However, I need to improve it.
