方法一、通過 Dockerfile構(gòu)建

創(chuàng)建Dockerfile

首先，創(chuàng)建目錄nginx,用于存放后面的相關(guān)東西。

w3cschool@w3cschool:~$ mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf

www目錄將映射為nginx容器配置的虛擬目錄

logs目錄將映射為nginx容器的日志目錄

conf目錄里的配置文件將映射為nginx容器的配置文件

進(jìn)入創(chuàng)建的nginx目錄，創(chuàng)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;"]

通過Dockerfile創(chuàng)建一個(gè)鏡像，替換成你自己的名字

docker build -t nginx .

創(chuàng)建完成后，我們可以在本地的鏡像列表里查找到剛剛創(chuàng)建的鏡像

w3cschool@w3cschool:~/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鏡像

w3cschool@w3cschool:~/nginx$ docker search nginx

...

這里我們拉取官方的鏡像

w3cschool@w3cschool:~/nginx$ docker pull nginx

等待下載完成后，我們就可以在本地鏡像列表里查到REPOSITORY為nginx的鏡像。

使用nginx鏡像

運(yùn)行容器

w3cschool@w3cschool:~/nginx$ docker run -p 80:80 --name mynginx -v $PWD/www:/www -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf -v $PWD/logs:/wwwlogs  -d nginx  
45c89fab0bf9ad643bc7ab571f3ccd65379b844498f54a7c8a4e7ca1dc3a2c1e
w3cschool@w3cschool:~/nginx$

命令說明：

  • -p 80:80：將容器的80端口映射到主機(jī)的80端口

  • --name mynginx：將容器命名為mynginx

  • -v $PWD/www:/www：將主機(jī)中當(dāng)前目錄下的www掛載到容器的/www

  • -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf：將主機(jī)中當(dāng)前目錄下的nginx.conf掛載到容器的/etc/nginx/nginx.conf

  • -v $PWD/logs:/wwwlogs：將主機(jī)中當(dāng)前目錄下的logs掛載到容器的/wwwlogs

查看容器啟動(dòng)情況

w3cschool@w3cschool:~/nginx$ docker ps
CONTAINER ID        IMAGE        COMMAND                      PORTS                         NAMES
