docker+nginx構建鏡像，部署靜態頁面

今天收到一個需求，要部署一個H5頁面，多簡單。既然是靜態頁面，那只需要構建一個nginx就可以了。

第一步：

構建nginx鏡像：我嘗試了兩種方法：

第一種：

直接拉取nginx鏡像，把程序打包拷貝進去就OK。

Dockerfile

FROM nginx
# COPY nginx.conf /etc/nginx/nginx.conf
COPY . /usr/share/nginx/html
COPY   nginx.conf /etc/nginx/nginx.conf
WORKDIR /usr/share/nginx/html
CMD ["nginx","-g","daemon off;"]

跑一下build就行了。

docker build -f dockerfile -t nginx:v1 .

缺點：nginx版本無法自定義。

 

第二種：拉取一個centos:7基礎鏡像，打包nginx成新鏡像

FROM centos:7

WORKDIR /usr/local/src
RUN yum install -y wget

RUN wget http://nginx.org/download/nginx-1.7.8.tar.gz

RUN tar zxvf nginx-1.7.8.tar.gz

WORKDIR nginx-1.7.8

RUN yum -y install gcc gcc-c++ pcre-devel zlib-devel openssl*
RUN useradd -M -u 40 -s /sbin/nologin nginx
RUN ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-file-aio --with-http_stub_status_module --with-http_gzip_static_module --with-http_flv_module --with-http_ssl_module --with-http_realip_module
RUN make
RUN make install

RUN ln -s /usr/local/nginx/sbin/* /usr/local/sbin/
RUN /usr/local/nginx/sbin/nginx

RUN echo "daemon off;">>/usr/local/nginx/conf/nginx.conf

ADD run.sh /usr/local/sbin/run.sh
RUN chmod 755 /usr/local/sbin/run.sh

RUN mkdir -p   /data/www && chown -R 755 /data/www 

WORKDIR /data/www

#COPY  index.html /data/www

#COPY nginx.conf /usr/local/nginx/conf/nginx.conf

EXPOSE 80 443

CMD ["/usr/local/sbin/run.sh"]

兩個 COPY的作用是把程序文件和nginx配置文件拷貝進容器進行替換。

nginx.conf配置文件：

user root;  #modify
worker_processes auto;  #modify

worker_rlimit_nofile 51200;


events {
    use epoll;
    worker_connections 51200;
    multi_accept on;
}


http {
    include      types;
    default_type  application/octet-stream;

    client_max_body_size 100m;  
    sendfile        on;
    
    keepalive_timeout  120; #65;

    #gzip  on;

    server {
        listen       80;
        server_name  cj.juyunka.com;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        root  /usr/share/nginx/html;
        index   index.html index.htm;
        
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
       
    }
 
    #include vhost/*.conf;

}
