À l'aide de Docker j'obtiens l'erreur: SQLSTATE[HY000] [2002] No such file or directory”

Je suis en utilisant le Panneau de créer un conteneur pour tester mon application web construit sur PHP et MySQL sur mon Mac. Mon PHP app est construit à l'aide de la Graisse Sans Cadre pour MVC et de routage. J'ai deux Dockerfiles, un pour MySQL et un pour PHP. J'ai utilisé de test Docker applications avec succès, alors je crois que mes images sont correctement installés.

La partie principale de l'erreur:

Internal Server Error

SQLSTATE[HY000] [2002] No such file or directory

[fatfree/lib/DB/SQL.php:466] PDO->__construct('mysql:host=127.0.0.1;port=3306;dbname=robohome','root','password',array(1002=>'SET NAMES utf8;'))
[fatfree/app/Controllers/Controller.php:24] DB\SQL->__construct('mysql:host=127.0.0.1;port=3306;dbname=robohome','root','password')

Remarque, si je le connecte à l'aide de 127.0.0.1 au lieu de localhost - je obtenir un peu différente d'erreur qui dit: SQLSTATE[HY000] [2002] Connection refused

Mon PHP Dockerfile:

FROM php:5.6-apache

RUN docker-php-ext-install mysqli pdo pdo_mysql
RUN a2enmod rewrite

Mon MySQL Dockerfile:

FROM mysql:5.7

ENV MYSQL_ROOT_PASSWORD password
ENV MYSQL_DATABASE robohome

COPY ./schema.sql /docker-entrypoint-initdb.d/

Mon Controller.php fichier dans lequel l'erreur mentionne ligne 24:

<?php

namespace Controllers;

class Controller
{
    protected $f3;
    protected $db;

    public function __construct()
    {
        $f3 = \Base::instance();
        $this->f3 = $f3;

        $mysqlServerName = $f3->get("MYSQL_SERVERNAME");
        $mysqlDatabseName = $f3->get("MYSQL_DBNAME");

        //$container = \DI\ContainerBuilder::buildDevContainer(); <-Not used currently

        //Below is line 24 referred to in the error
        $db = new \DB\SQL(
            "mysql:host={$mysqlServerName};port=3306;dbname={$mysqlDatabseName}",
            $f3->get("MYSQL_USERNAME"),
            $f3->get("MYSQL_PASSWORD")
        );

        $this->db = $db;
    }

Ceux MYSQL_* valeurs sont extraites d'un .ini fichier:

MYSQL_SERVERNAME = "localhost" <-This is what I've tried changing to 127.0.0.1
MYSQL_USERNAME = "root"
MYSQL_PASSWORD = "password"
MYSQL_DBNAME = "robohome"

Mon menu fixe composer fichier:

version: '2'

services:
  web:
    build: ./docker/php
    ports:
      - 80:80
    volumes:
      - .:/var/www/html/
    links:
      - db
  db:
    build: ./docker/mysql
    ports:
      - 3306

Je l'exécute en faisant docker-compose up --build -d. La sortie alors je peux obtenir à partir de docker ps est:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                     NAMES

Si je suis à court de premier plan au lieu de cela, j'obtiens le résultat suivant:

De mes recherches, j'ai essayé de connecter à l'aide de deux localhost et 127.0.0.1 depuis qu'ils sont techniquement de les traiter différemment. Il pourrait aussi être quelque chose lié à essayer de parler via des sockets à la place de TCP. Idéalement, je voudrais une solution que je peux cuire dans mon Dockerfiles donc je n'ai pas à vous soucier de se souvenir des commandes ou comment j'ai fait quelque chose.

Eh bien, qu'est-ce que mysql configuré pour écouter sur? Le Port 3306 (par défaut pour le protocole TCP) ou un fichier de socket?
Basé sur mon commentaire ci-dessus (vous avez faites défiler vers la droite pour le voir) 0.0.0.0:32777->3306/tcp
Modifié pour inclure de mon menu fixe composer de fichier.
