Cannot access docker nginx image on localhost - OSX

Question

I was given a repo containing a PHP Application using Docker/Symfony. I'm able to successfully run docker-compose up --build and it looks like everything is running successfully. When I run docker ps --all I see everything I'm expecting

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES
65d7f22b6b13        nginx               "nginx -g 'daemon ..."   16 minutes ago      Up 7 minutes        0.0.0.0:8086->80/tcp   symfony_nginx_1
4fa3c58d1eea        symfony_fpm         "docker-php-entryp..."   16 minutes ago      Up 7 minutes        9000/tcp               symfony_fpm_1
7316d40b1b8c        mysql:5.5           "docker-entrypoint..."   16 minutes ago      Up 7 minutes        3306/tcp               symfony_mysql_1
cac0757e2f6d        redis:latest        "docker-entrypoint..."   16 minutes ago      Up 7 minutes        6379/tcp               symfony_redis_1

When I try to access localhost:8086 on my browser, I get connection refused. I though maybe my local config might be janky and tried this on another machine with the same results. I tried to get the logs of the nginx image by running docker logs 65d7f22b6b13 but it returns nothing.

Is there something I'm not understanding about docker/nginx and port forwarding that I'm doing incorrectly? Below is my docker config

version: '2'

services:
  nginx:
    image: nginx
    ports:
      - "8086:80"
    volumes:
      - ./:/var/www/symfony
      - ./docker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
    links:
      - fpm

  fpm:
    build: docker/php-fpm/
    links:
      - redis
      - mysql
    volumes:
      - ./:/var/www/symfony
      - ./docker/php-fpm/php-ini-overrides.ini:/usr/local/etc/php/conf.d/99-overrides.ini

  mysql:
    image: mysql:5.5
    environment:
      MYSQL_DATABASE: devdb
      MYSQL_USER: devdb
      MYSQL_PASSWORD: devdb
      MYSQL_ROOT_PASSWORD: root
    volumes:
      - ./backup.sql.gz:/docker-entrypoint-initdb.d/backup.sql.gz

  redis:
    image: redis:latest

I'm on OSX 10.11.6 - Any help appreciated. Symfony and Docker are new to me.

edit Below is my nginx config file - I updated listen to use 127.0.0.1:8086 but still see it using 0.0.0.0 when I run docker ps

server {
    listen 127.0.0.1:80 default;

    client_max_body_size 108M;

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

    root /var/www/symfony/web;

    rewrite ^/index\.php/?(.*)$ /$1 permanent;

    try_files $uri @rewriteapp;

    location @rewriteapp {
        rewrite ^(.*)$ /index.php/$1 last;
    }

    # Deny all . files
    location ~ /\. {
        deny all;
    }

    location ~ ^/index\.php(/|$) {
        fastcgi_pass fpm:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        fastcgi_index index.php;
        send_timeout 1800;
        fastcgi_read_timeout 1800;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PHP_VALUE "error_log=/var/log/nginx/routemap3_php_errors.log";
        fastcgi_buffers 16 16k;
        fastcgi_buffer_size 32k;
        include fastcgi_params;
    }

    # Statics
        location /(bundles|media) {
        access_log off;
        expires 30d;
        try_files $uri @rewriteapp;
    }

}

Your answer is in your question:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES
65d7f22b6b13        nginx               "nginx -g 'daemon ..."   16 minutes ago      Up 7 minutes        0.0.0.0:8086->80/tcp   symfony_nginx_1

Now if you read the column PORTS carefully you will see 0.0.0.0:8086->80/tcp , which means that your local loop 0.0.0.0 on port 8086 is mapped to the port 80 of your ngnix container, and this with the tcp protocol.

So your correct url to access is http://0.0.0.0:8086/

You will also have to change your NGINX config to adapt to that, it should read:

listen 0.0.0.0:80;

or even better:

listen *:80;
