这篇博客介绍了如何在没有网络的CentOS 7.9环境中安装Docker CE。首先提供了适用于RHEL/CentOS 7的Docker RPM包下载地址，然后详细展示了下载所需包及依赖包的过程。通过`yum install`命令离线安装了包括docker-ce在内的5个主要包以及4个依赖包。最后，提到了安装完成后启动和检查Docker服务的命令。

适用于RHEL/CentOS 7的 rpm 包下载地址：

Index of linux/centos/7/x86_64/stable/Packages/ (docker.com)https://download.docker.com/linux/centos/7/x86_64/stable/Packages/ 官方需要下载的包共计 5 个，如下所示：

下载完成后，将上面的包上传到CentOS7.9系统中，然后离线下载所需的其它依赖包，依赖包的下载数量与系统安装的模式有关，如：GUI模式和最小化模式，所需的依赖包数量是不一样的。

下载完成后，即可使用下面的命令执行安装

$ rpm -ivh *.rpm

$ systemctl enable docker.service

$ systemctl start docker.service

$ systemctl status docker.service

下载离线包的原因是因为我们在生产环境安装的时候，绝大多数的生产环境都是与外网隔离的，所以就需要提前下载好安装所需的离线rpm包。
