2.搜索並下載nginx容器
[root@Docker ~]# docker search nginx
[root@Docker ~]# docker pull docker.io/nginx
3.將容器的80端映射到本機的8080
[root@Docker ~]# docker run --name=nginx -itd -p8080:80 docker.io/nginx bash
或者
[root@Docker ~]# docker run --name nginx -itd -p8080:80 docker.io/nginx /bin/bash
或者
[root@Docker ~]# docker run --name=nginx -itd -p8080:80 docker.io/nginx
4.查看docker容器進程
[root@Docker ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
26ae21c8bddd 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
[root@Docker ~]# docker inspect 0a9db4be695b |grep -i ip
"HostIp": "",
"IpcMode": "",
"LinkLocalIPv6Address": "",
"LinkLocalIPv6PrefixLen": 0,
"HostIp": "0.0.0.0",
"SecondaryIPAddresses": null,
"SecondaryIPv6Addresses": null,
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"IPAddress": "172.17.0.2",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"IPAMConfig": null,
"IPAddress": "172.17.0.2",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
[root@Docker ~]#
6.瀏覽器訪問測試：
http://IP:8080
7.登錄進入容器中，更改默認的測試頁面內容 [root@Docker ~]# docker exec -it 0a9db4be695b /bin/bash root@0a9db4be695b:/# cd /usr/share/nginx/html/ root@0a9db4be695b:/usr/share/nginx/html# ls 50x.html index.html root@0a9db4be695b:/usr/share/nginx/html# echo "<h1>www.hello.com</h1>"> index.html root@0a9db4be695b:/usr/share/nginx/html# exit exit [root@Docker ~]# 8.瀏覽器訪問測試： http://IP:8080
9.強制刪除所有的虛擬機 [root@Docker ~]# docker rm -f `docker ps -aq`
