Symfony2的Docker容器中的权限问题

我想创建一个Docker镜像来引导Symfony项目.这是我的Dockerfile:

FROM php:7-apache

LABEL Description = "This image is used to start Symfony3 project"

ENV DIRPATH /var/www/html

# apt-get command
RUN apt-get update && apt-get install -y \
    vim \
    git
RUN apt-get install -y zlib1g-dev && docker-php-ext-install zip


# Install Composer
RUN curl -sS https://getcomposer.org/installer | php
RUN mv composer.phar /usr/local/bin/composer

# Install the Symfony Installer
RUN curl -LsS http://symfony.com/installer -o /usr/local/bin/symfony
RUN chmod a+x /usr/local/bin/symfony

# Create the php.ini file
RUN cp /usr/src/php/php.ini-development /usr/local/etc/php/php.ini

构建和容器创建工作正常,但我的容器中有权限问题.当我要去app_dev.php时,我收到了这条消息:

您无权访问此文件.检查app_dev.php以获取更多信息.

显然,我只能使用localhost访问此文件.此外,PHP无法在我的容器中删除或创建任何内容.例如,我在运行时遇到以下错误:

$php app/console cache:clear
Failed to remove directory "/var/www/html/app/cache/dev_old/doctrine

我怎样才能在Dockerfile中解决这个问题？

终于在几周后找到了它:

在你的Dockerfile中添加它.它解决了许可问题.

# Workaround for write permission on write to MacOS X volumes

RUN usermod -u 1000 www-data
