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。
runoob@runoob:~$ mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf
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
FROM debian:jessieMAINTAINER NGINX Docker Maintainers "docker-maint@"ENV NGINX_VERSION 1.10.1-1~jessieRUN apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 \&& echo "deb /packages/debian/ jessie nginx" >> /etc/apt/sources.list \&& apt-get update \&& apt-get install --no-install-recommends --no-install-suggests -y \ca-certificates \nginx=${NGINX_VERSION} \nginx-module-xslt \nginx-module-geoip \nginx-module-image-filter \nginx-module-perl \nginx-module-njs \gettext-base \&& rm -rf /var/lib/apt/lists/*# forward request and error logs to docker log collectorRUN ln -sf /dev/stdout /var/log/nginx/access.log \&& ln -sf /dev/stderr /var/log/nginx/error.logEXPOSE 80 443CMD ["nginx", "-g", "daemon off;"]
通过Dockerfile创建一个镜像，替换成你自己的名字
docker build -t nginx .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/nginx$ docker images nginxREPOSITORYTAG IMAGE IDCREATED SIZEnginx latest 555bbd91e13c 3 days ago182.8 MB
方法二、docker pull nginx
查找Docker Hub上的nginx镜像
runoob@runoob:~/nginx$ docker search nginxNAME DESCRIPTION STARS OFFICIAL AUTOMATEDnginx Official build of Nginx. 3260 [OK] jwilder/nginx-proxy Automated Nginx reverse proxy for docker c... 674 [OK]richarvey/nginx-php-fpm Container running Nginx + PHP-FPM capable ... 207 [OK]million12/nginx-php Nginx + PHP-FPM 5.5, 5.6, 7.0 (NG), CentOS... 67[OK]maxexcloo/nginx-php Docker framework container with Nginx and ... 57[OK]webdevops/php-nginx Nginx with PHP-FPM39[OK]h3nrik/nginx-ldapNGINX web server with LDAP/AD, SSL and pro... 27[OK]bitnami/nginx Bitnami nginx Docker Image 19[OK]maxexcloo/nginxDocker framework container with Nginx inst... 7[OK]...
这里我们拉取官方的镜像
runoob@runoob:~/nginx$ docker pull nginx
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。使用nginx镜像
运行容器
runoob@runoob:~/nginx$ docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs -d nginx 45c89fab0bf9ad643bc7ab571f3ccd65379b844498f54a7c8a4e7ca1dc3a2c1erunoob@runoob:~/nginx$
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 $PWD/logs:/wwwlogs：将主机中当前目录下的logs挂载到容器的/wwwlogs
查看容器启动情况
runoob@runoob:~/nginx$ docker psCONTAINER ID IMAGE COMMAND PORTS NAMES45c89fab0bf9 nginx "nginx -g 'daemon off" ... 0.0.0.0:80->80/tcp, 443/tcp mynginxf2fa96138d71 tomcat "catalina.sh run" ... 0.0.0.0:81->8080/tcptomcat
