Docker服务无法构建：返回非零代码1

我尝试使用docker为php安装一些所需的扩展 .

这是我的Dockerfile：

FROM php:7-fpm

RUN apt-get update && apt-get install -y \
    libfreetype6-dev \
    libjpeg62-turbo-dev \
    libmcrypt-dev \
    libpng12-dev \
    libsqlite3-dev \
    libssl-dev \
    libcurl3-dev \
    libxml2-dev \
    libzzip-dev \
&& docker-php-ext-install iconv json mcrypt mbstring mysql mysqli pdo_mysql pdo_sqlite phar curl ftp hash session simplexml tokenizer xml xmlrpc zip \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install gd

WORKDIR /var/www

CMD ["php7-fpm"]

这是我得到的错误：

您是否在我的Dockerfile中看到任何问题，或者问题出在其他地方？

php docker hub让我对这个Dockerfile感到鼓舞 .
