方法一、通过 Dockerfile构建
创建Dockerfile
首先，创建目录nginx,用于存放后面的相关东西。
[root@huixuan ~]# mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf
[root@huixuan ~]# ls
anaconda-ks.cfg  Dockerfile  nginx  vpd.properties
[root@huixuan ~]# 


www目录将映射为nginx容器配置的虚拟目录
logs目录将映射为nginx容器的日志目录
conf目录里的配置文件将映射为nginx容器的配置文件
进入创建的nginx目录，创建Dockerfile


[root@huixuan nginx]# cat Dockerfile 
FROM debian:jessie

ENV NGINX_VERSION 1.10.1-1~jessie


RUN apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 \
        && echo "deb http://nginx.org/packages/debian/ jessie nginx" >> /etc/apt/sources.list \
        && apt-get update \
        && apt-get install --no-install-recommends --no-install-suggests -y \
                                                ca-certificates \
                                                nginx=${NGINX_VERSION} \
                                                nginx-module-xslt \
                                                nginx-module-geoip \
                                                nginx-module-image-filter \
                                                nginx-module-perl \
                                                nginx-module-njs \
                                                gettext-base \
        && rm -rf /var/lib/apt/lists/*


# forward request and error logs to docker log collector
RUN ln -sf /dev/stdout /var/log/nginx/access.log \
        && ln -sf /dev/stderr /var/log/nginx/error.log


EXPOSE 80 443


CMD ["nginx", "-g", "daemon off;"]

通过Dockerfile创建一个镜像，替换成你自己的名字
[root@huixuan nginx]# docker build -t nginx .

[root@huixuan nginx]# 








创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
方法一本人没有创建成功。








方法二、docker pull nginx
查找Docker Hub上的nginx镜像
[root@huixuan nginx]# docker search nginx


这里我们拉取官方的镜像




等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为nginx的镜像。
[root@huixuan nginx]# docker pull nginx
Using default tag: latest
Trying to pull repository docker.io/library/nginx ...

Status: Downloaded newer image for docker.io/nginx:latest
[root@huixuan nginx]# 




使用nginx镜像
运行容器


[root@huixuan nginx]# docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs  -d nginx 
c782a8c09f261929ef26fe5cbcebc85dd9dda76c97475878f77b8a2ad3faa175

: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type.
[root@huixuan nginx]# 


通过下面的命令启动
[root@huixuan nginx]# docker run -p 80:80 --name mynginx1111 -d nginx 
e5f669143490eb6dd86816da584c375d17f9ca137b8d061e9251536f7172233d
[root@huixuan nginx]# 






命令说明：
-p 80:80：将容器的80端口映射到主机的80端口
--name mynginx：将容器命名为mynginx
-v $PWD/www:/www：将主机中当前目录下的www挂载到容器的/www
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf：将主机中当前目录下的nginx.conf挂载到容器的/etc/nginx/nginx.conf
-v $PWD/logs:/wwwlogs：将主机中当前目录下的logs挂载到容器的/wwwlogs
查看容器启动情况




[root@huixuan nginx]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                NAMES
