介绍

Dockerc 它是一个容器镜像编译器，可以将Docker容器镜像编译成独立的可移植二进制文件。这意味着用户不再需要使用docker run命令来运行容器，也不需要使用pip install或npm i来安装软件包，而是可以直接运行编译后的可执行文件。

编译后的二进制文件可以像普通二进制文件一样被调用。此外，网络服务在容器内部运行时，用户可以直接访问，而无需指定-p参数来映射端口。

这个项目对于希望简化容器部署和管理的用户来说非常有用，尤其是那些希望避免复杂的Docker命令行操作的用户。

安装webman

composer create-project workerman/webman tinywan-docker-webman

wget 

解压即可得到一个PHP可执行文件，可直接使用，无需安装PHP环境。目前只支持Linux系统。通常下载x86_64架构。下载地址

解压后会生成一个二进制PHP文件

tar -zxvf php-8.2.8-static-bin-x86_64.tar.gz
