镜像（每个镜像的id值都不一样）
podman images
podman load -i /root/httpd.tar.gz
podman images
podman load -i /root/nginx.tar.gz
podman images
podman load -i /root/myos.tar.gz

容器（每个容器的id值都不一样）
podman run -it localhost/myos:httpd /bin/bash # /bin/bash解释器为'启动命令'
cat /etc/redhat-release
useradd dc
id dc
exit
podman ps -a
podman start 03
podman exec -it 03 /bin/bash
id dc
exit
podman ps -a
podman stop 03
podman rm 03
podman ps -a
容器放入后台并创建名字
podman run --name abc01 -itd localhost/myos:httpd /bin/bash
podman ps -a
podman exec -it abc01 /bin/bash
useradd tc
id tc
exit
podman stop abc01
podman rm abc01
podman ps -a
容器放入后台，端口绑定
podman run --name nsdweb -p 80:80 -itd localhost/myos:httpd /bin/bash
podman ps -a
podman exec -it nsdweb /bin/bash
echo wo shi nsdweb > /var/www/html/index.html
/usr/sbin/httpd
exit
curl http://192.168.4.100 #真机访问
终极容器
podman stop nsdweb
podman rm -f nsdweb
podman run --name rqweb -p 80:80 -v /opt:/var/www/html -itd localhost/myos:httpd /bin/bash
podman exec -it rqweb /bin/bash
/usr/sbin/httpd
exit
echo wo shi zhenji > /opt/index.html #真机
curl http://192.168.4.100 #真机
