This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps:1. The Docker client contacted the Docker daemon.2. The Docker daemon pulled the "hello-world" image from the Docker Hub.(amd64)3. The Docker daemon created a new container from that image which runs theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/若能正常输出以上信息，则说明安装成功。

原因：这些错误表明 Docker 无法找到 iptables 命令，它是用于配置网络规则和转发的重要工具。缺少 iptables 可能会导致 Docker 无法初始化网络控制器，从而无法启动。
解决方法
# 检查 iptables 是否已安装

root@ubuntu2204:~# apt-get install iptables # 或重新安装：apt-get install --reinstall iptables# 再次启动 docker
