docker镜像制作 centos6 nginx1.15.6 with NGINX_UPSYNC_MODULE

首先我选择了在centos6里部署nginx的镜像，如果大家选择的是centos7,自己重新修改吧

这里的问题点有几个：

1，make的版本选择，因为我下载了最新的cmake,需要c++11编译

     这玩意的安装比较麻烦，在前面一篇随笔里已经写过gcc在centos里的安装

2，docker容器的层级，我使用了 以下办法来减少层级，不在同一个层级，有些操作会出现问题哦

     RUN .....   

      && .....

3，CMD和Endpoint的使用，我这里只用了endpoint，但nginx作为后台运行，需要额外添加参数

    ENTRYPOINT ["/usr/local/nginx/sbin/nginx","-g","daemon off;"]

4，调试，在调试过程中最好使用“docker run -itd nginx_centos6”，把-itd改为-it,这样能够查看到出错信息

5，真正部署时，我使用了dockercompose文件，可以让很多参数进行额外的配置

}

创建镜像

docker build -t nginx_centos6 ./

启动镜像

docker run -it nginx_centos6

这样启动后，正常来说使用http://127.0.0.1是访问拒绝的，因为Docker里有自己的IP，需要隐射一下

我选择使用了docker_compose来配置隐射

services:
  nginx0:
    image: nginx_centos6
    restart: always
    container_name: nginx0
    ports:
      - 80:80

　　执行docker-compose -f docker-compose-nginx.yaml up -d 2>&1

一切OK
