修改了 Dockerfile 文件 | Modified Dockerfile

[findlayfeng]

• 修改了运行时依赖的处理方式，通过对 PHP插件的库连接情况自动处理保留的包
• PHP 的默认的配置文件通过link的方式链接到 production 文件
• 修改了 apache 的默认 root 文件夹和其他环境做统一
• 通过版本 环境变量SMARTY_VERSION 安装不同版本的 SMARTY
• 通过 Multi-stage builds 的方式构建镜像
• 删除了 .dockerignore 文件 通过 INSTALL_PATHS 变量的方式指定需要发布的路径，好处是添加了新的路径后需要显式的添加到发布列表，而不是默认发布，这个文件 5年没有修改了，显然的将不少不必要的文件发布到了docker镜像

• Modified the handling of runtime dependencies, automatically handling the retained packages by checking the library connection of the PHP plugin
• PHP's default configuration file is linked to the production file through link
• Modified the default root folder of apache to unify with other environments
• Install different versions of SMARTY through the version environment variable SMARTY_VERSION
• Build images through Multi-stage builds
• Deleted .dockerignore file The path to be published is specified through the INSTALL_PATHS variable. The advantage is that after adding a new path, it needs to be explicitly added to the release list instead of being published by default. This file has not been modified for 5 years. Obviously, many unnecessary files are published to the docker image.
