How to change localhost to domain in nginx docker-compose container?

Question

Nginx

All good time.
Can you tell me how you can use your domain name instead of 'localhost' ?
Here is the basic configuration:
docker-compose.yml

version: '2'
services:
    web:
        build:
            context: ./
            dockerfile: web.docker
        volumes:
            - ./:/var/www/html
        ports:
            - "80:80"
        links:
            - app
    app:
        build:
            context: ./
            dockerfile: app.docker
        volumes:
            - ./:/var/www/html

vhost.conf

server {
    listen 80;
    index index.php index.html;
    root /var/www/html/public;

    location / {
        try_files $uri /index.php?$args;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

web.docker

FROM nginx:1.10

ADD ./vhost.conf /etc/nginx/conf.d/default.conf
WORKDIR /var/www/html

app.docker

FROM php:7-fpm

RUN apt-get update && apt-get install -y libmcrypt-dev mysql-client \
    && docker-php-ext-install mcrypt pdo_mysql

WORKDIR /var/www/html

Answer 1

Insert a line in the first block of the vhost.conf file
And yes, docker has nothing to do with it, you just don't have nginx configured.
