Lumen - Postgresql设置 - Composer

Question

真的很喜欢这个，它不是我试图设置它的第一个，但我真的不明白它为什么不起作用。

所以这是我的app.docker文件：

FROM php:7-fpm
# Install modules
RUN buildDeps="libpq-dev libzip-dev libfreetype6-dev libjpeg62-turbo-dev libpng-dev " && apt-get update && apt-get install -y $buildDeps --no-install-recommends && rm -rf /var/lib/apt/lists/* \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install pdo pdo_pgsql pgsql gd

WORKDIR /var/www

COPY . /var/www

RUN chown www-data:www-data -R ./storage

RUN ln -s /storage/app/public /public

非常简单。接下来是phpinfo（）的输出

我知道现在已经安装了pgsql驱动程序，但是，当运行php artisan migrate时我还是得到了

这是我的config / database.php文件。

            'database' => env('DB_PG_DATABASE', 'dockerApp'), // This seems to be ignored
            'port'     => env('DB_PG_PGSQL_PORT', 5432),
            'username' => env('DB_PG_USERNAME', 'postgres'),

            'database' => 0,

我能错过什么？
