Docker 上的本地主机有“冲突的服务器名称”问题

Question

I am trying to launch a docker image with localhost. The code is open sourced and here:

https://github.com/Helium-MVC/Boilerplate

When I run docker-compose up , I get the following:

helium_nginx | 2018/12/11 07:43:31 [warn] 1#1: conflicting server name "localhost" on 0.0.0.0:80, ignored
helium_nginx | nginx: [warn] conflicting server name "localhost" on 0.0.0.0:80, ignored

Now my docker site.conf only has 1 vhost:

server {
    #The port to listen on. SSL would listen on 443
    listen 80 default_server;

    #The name/alias the server listens for when deciding to use this configuration
    server_name  localhost _;

    #Where the lo files are being written too
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;

    #Location of our site
    location / {
            #The root of the site is in public_html
        root    /code/site/public_html/;
        index  index.php index.html index.htm;
        #important for pretty url and routing
        try_files $uri $uri/ /index.php?rt=$uri&$args;
    }                                                                 
}

With it set in the yml like so:

web:
    image: nginx:latest
    container_name: "helium_nginx"
    ports:
      - "8000:80"
    volumes:
      - ./:/code
      - ./site.conf:/etc/nginx/conf.d/site.conf
      - ./nginx_custom_settings.conf:/etc/nginx/conf.d/nginx_custom_settings.conf
    links: ['php']

What is weird is that is if I change the server_name to something like www.example.com and place that name in my /etc/hosts file, it works ! Otherwise using localhost I get only the nginx default page . What can be wrong?

To provide an answer, I had to change the default nginx configuration. In my YML I added:

services:
  web:
    image: nginx:latest
    container_name: "helium_nginx"
    ports:
      - "8000:80"
    volumes:
      - ./:/usr/share/nginx/html
      - ./:/code
      - ./site.conf:/etc/nginx/conf.d/site.conf
    additionnx.conf:/etc/nginx/nginx.conf

The addittion was the -./nginx.conf:/etc/nginx/nginx.conf

The nginx.conf being copied was this:

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/site.conf;
}

What I changed was instead of having include /etc/nginx/conf.d/*.conf; that would load all configuration, I loaded just the one I wanted, include /etc/nginx/conf.d/site.conf;

I'm using the nginx image in docker, which has a default.conf file with server_name localhost and listening port 80. I simply replace that file and get this resolved.

docker-compose.yml

version: '2'
services:
  nginx: 
    image: nginx:latest
    volumes:
      - ./tmp/https_reverse_proxy.conf:/etc/nginx/conf.d/https_reverse_proxy.conf
      - ./tmp/http_reverse_proxy.conf:/etc/nginx/conf.d/default.conf
    ports:
      - 80:80
      - 443:443

and http_reverse_proxy.conf

server {
  listen 80;

  server_name localhost;

  return 301 https://$host$request_uri;
}
