# Как подключиться к хосту локальному (к бд, например) из докер контейнера

1\) Помогло только использование network\_mode: host

Т.е. в таком случае сеть докера как бы вливается в сеть локальную.

Пример:

```
version: '3'

services:

  web:
    container_name: picfind-web
    image: nginx:1.15.10-alpine
    restart: always
    ports: ["86:80"]
    volumes:
      - ../../:/app
      - ../logs:/logs
      - ../common/host.conf:/etc/nginx/conf.d/default.conf
    depends_on:
      - app
    network_mode: host
```

Сервисы в конфиге, которые указывались по имени днс, теперь нужно указать как localhost. И видимо эти сервисы не должны перекрывать локальные порты:

Плюс значение **ports** не имеет значение в docker compose. Нужно указать свободный локальный порт в конфиге нгинкс такой же, что и был в докер-контейнер, чтобы был таким же, что и раньше:

Было: 

```
server {
    charset utf-8;
    client_max_body_size 256M;

    listen 80 default_server;

    server_name localhost;
    root        /app;
    index       index.php;

    access_log  /logs/access.log;
    error_log   /logs/error.log;

    location / {
        # Redirect everything that isn't a real file to index.php
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_read_timeout 3600;
        fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
    }

    location ~ /\.(ht|svn|git) {
        deny all;
    }
}

```

Стало: 

```
server {
    charset utf-8;
    client_max_body_size 256M;

    listen 86 default_server;

    server_name localhost;
    root        /app;
    index       index.php;

    access_log  /logs/access.log;
    error_log   /logs/error.log;

    location / {
        # Redirect everything that isn't a real file to index.php
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass localhost:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_read_timeout 3600;
        fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
    }

    location ~ /\.(ht|svn|git) {
        deny all;
    }
}

```
