Docker 安装 Nginx

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。

renren@renren:~$ 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:jessie

MAINTAINER NGINX Docker Maintainers "docker-maint@nginx.com"

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

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

renren@renren:~/nginx$ docker images nginx
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
nginx               latest              555bbd91e13c        3 days ago          182.8 MB

方法二、docker pull nginx

查找Docker Hub上的nginx镜像

renren@renren:~/nginx$ docker search nginx
NAME                      DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED

...

这里我们拉取官方的镜像

renren@renren:~/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

renren@renren:~/nginx$ docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs  -d nginx  
45c89fab0bf9ad643bc7ab571f3ccd65379b844498f54a7c8a4e7ca1dc3a2c1e
renren@renren:~/nginx$

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

renren@renren:~/nginx$ docker ps
CONTAINER ID        IMAGE        COMMAND                      PORTS                         NAMES
