Production docker service of the mirror

Mirroring

Manual production yum mirror source nginx

1, into the container

$ docker run -it -p 8802:80

2, container operations

$ yum install wget -y

$ rm -rf ./etc/yum.repos.d/*
 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

$ wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
$ yum install -y vim wget pcre pcre-devel zlib zlib-devel openssl openssl-devel iproute net-tools iotop

$ yum install nginx –y
$ vim /etc/nginx/nginx.conf
daemon off;
      


server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        }
# 添加location      
  location /pansn {
             root /data/nginx/html;
             index index.html;
}



$ mkdir -p /data/nginx/html/pansn
$ echo "test linux37" > /data/nginx/html/pansn/index.html
$ mv 1.jpg /data/nginx/html/pansn



3、创建镜像
重开一个终端窗口创建镜像

$ docker commit -a "[email protected]" -m "nginx yum v1" --change="EXPOSE 80 443" 373b8f018f4c docker.io/linux37/centos-nginx:v1

$ docker commit -a "[email protected]" -m "nginx yum  v1" --change="EXPOSE 80 443" 05b7e99cf4b8 www.pansn.cn/linux37/centos-nginx:v1

4、启动镜像并传递命令nginx启动命令
$ docker run -d -it -p 82:80 www.pansn.cn/linux37/centos-nginx:v1 nginx 
$ ss -ntl  #确定82端口是否开启成功

verification

Finally, the backup image to another terminal authentication guide

$ docker save www.pansn.cn/linux37/centos-nginx:v1 > /opt/nginx-v1

$ ll /opt

 导入镜像并启动

映射端口
$ docker run -it -d -p 80:80 www.pansn.cn/linux37/centos-nginx:v1 nginx

DockerFile production version of nginx yum mirror

DockerFile can be said that the script of which may be interpreted Docker program, a command is DockerFile bar composition, each command corresponding to a command linux following, these DockerFile Docker program instructions and then translated into a real linux commands, which have own writing systems and command support, the program reads DockerFile Docker Docker and generate the mirror according to the instruction, compared to manual to mirror the way, DockerFile more intuitive display mirroring is how to produce, with the DockerFile, when there is an additional late when needs, just add or modify the response before DockerFile command to regenerate a new Docke mirror, to avoid the trouble of repeated manual mirrored

Official dockerfile: https: //github.com/nginxinc/docker-nginx/blob/master/stable/buster/Dockerfile
environment to prepare:

nginx软件：
nginx-1.16.1.tar.gz

$ mkdir /data/nginx/html/linux37/apps -pv
$ vim /data/nginx/html/linux37/apps/index.html

$ useradd nginx -u 2019

Download base image Centos:

$ docker pull centos

Create a mirror directory:

$ mkdir  /opt/dockerfile/{web/{nginx,tomcat,jdk,apache},system/{centos,ubuntu,redhat}} -pv
