I wrote a Dockerfile. How can nginx’s configuration file read the files on the host computer?

  docker, question

This is my Dockerfile:

FROM centos
 MAINTAINER salamander  ********@qq.com
 RUN yum install -y pcre-devel wget net-tools gcc zlib zlib-devel make openssl-devel
 # Add File
 ADD  http://nginx.org/download/nginx-1.12.1.tar.gz
 RUN tar -zxvf  nginx-1.12.1.tar.gz .
 RUN mkdir -p /usr/local/nginx
 RUN cd nginx-1.12.1 && ./configure --prefix=/usr/local/nginx && make && make install
 RUN rm -vf /usr/local/nginx/conf/nginx.conf
 COPY ./nginx_conf /usr/local/nginx/conf/nginx.conf
 # Expose ports
 CMD service nginx start

I want to set the actual configuration file reading location of Nginx to/home/www/doc/etc/NGINX
The path of this Dockerfile is under /home/www/docker.

I want to ask,COPY .nginx_conf /usr/local/nginx/conf/nginx.confYou should have written it wrong. It should be writtenCOPY nginx_conf /usr/local/nginx/conf/nginx.confLet’s see. It is nginx.conf that covers docker.

If you want to set the configuration file directory, you can add it at startup.-vParameters:

docker run -d -v $PWD/etc/nginx:/usr/local/nginx/conf/ YOUR_IMAGE_NAME

However, I suggest nginx to directly use the official image.

FROM nginx:1.12
 COPY etc/nginx /etc/nginx/conf.d/
 ENTRYPOINT ["nginx", "-g", "daemon off;"  ]

Just wrote an article about docker, you canLook.
