关于Docker运行Nginx的文章层出不穷，鄙人推荐http://www.runoob.com/docker/docker-install-nginx.html这篇文章中介绍的两种方法。在这里，我着重介绍下第二种方法吧，直接从docker Hub上拉取Nginx镜像，供我们使用。

 这里，我在虚拟机中安装了CentOS7，然后，安装docker，这一步，就不必详细介绍了。假设，你已经成功安装了docker。我这里安装的版本是1.13.1,API版本1.26，

Client:
 Version:         1.13.1
 API version:     1.26
 Package version: <unknown>
 Go version:      go1.8.3
 Git commit:      774336d/1.13.1
 Built:           Wed Mar  7 17:06:16 2018
 OS/Arch:         linux/amd64

Server:
 Version:         1.13.1
 API version:     1.26 (minimum version 1.12)
 Package version: <unknown>
 Go version:      go1.8.3
 Git commit:      774336d/1.13.1
 Built:           Wed Mar  7 17:06:16 2018
 OS/Arch:         linux/amd64
 Experimental:    false

首先，创建一个目录：

mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf

命令进入nginx目录。

然后，我们通过docker search命令，来检索nginx镜像

docker search nginx

然后，通过docker pull命令，从远程拉取nginx镜像，命令如下：

docker pull nginx

拉取成功后，我们可以通过docker images命令，查看镜像：

[root@localhost nginx]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
docker.io/nginx     latest              ae513a47849c        4 weeks ago         109 MB

然后，通过docker run命令启动容器，运行镜像：

[root@localhost nginx]#  docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf --privileged=true -v $PWD/logs:/www/logs -v $PWD/html:/etc/nginx/html  -d nginx

这里，-v $PWD/www:/www把主机当前目录下的www目录绑定到了docker中www目录。需要注意的是，

由于docker容器需要对nginx.conf的访问权限，因此，绑定nginx.conf文件时，后面添加--privileged=true命令。

通过docker ps命令，查看容器运行状况
