运行一个nginx容器,命名为webserver，并将容器端口80映射到本机

docker run --name webserver -d -p 80:80 nginx

1.查看启动中的容器

docker ps -a

输出结果查看port可以看到端口映射情况

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5e62c8c47f18 nginx “nginx -g ‘daemon of…” 12 seconds ago Up 10 seconds 0.0.0.0:80->80/ tcp web

2.本地机器测试nginx服务

curl 127.0.0.1

执行结果显示服务成功访问

<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

另外我们可以通过命令查看docker端口映射

docker port web

输出结果:

80/tcp -> 0.0.0.0:80
