[[email protected] ~]# docker pull docker.io/nginx
3.将容器的80端映射到本机的8080[[email protected] ~]# docker run --name=nginx -itd -p8080:80 docker.io/nginx bash
或者[[email protected] ~]# docker run --name nginx -itd -p8080:80 docker.io/nginx /bin/bash
或者[[email protected] ~]# docker run --name=nginx -itd -p8080:80 docker.io/nginx
注:--privileged 给予管理员权限,--restart=always 容器随docker宿主机的启动而启动;CentOS7安装服务器后若使用systemctl工具启动创建容器时需要执行/usr/sbin/init或/sbin/init命令。
4.查看docker容器进程[[email protected] ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES26ae21c8bddd docker.io/nginx "bash" 5 seconds ago Up 4 seconds 0.0.0.0:8080->80/tcp nginx
5.查看docker容器IP地址[[email protected] ~]# docker inspect 0a9db4be695b |grep -i ip
"HostIp": "",
"IpcMode": "",
"LinkLocalIPv6Address": "",
"LinkLocalIPv6PrefixLen": 0,
"HostIp": "0.0.0.0",
"SecondaryIPAddresses": null,
"SecondaryIPv6Addresses": null,
"GlobalIPv6Address": "",
