运行缓存时允许的内存大小耗尽：清除和缓存：热身

Question

我正在使用 docker 运行 symfony 应用程序，并且有以下 Dockerfile：

# PHP Image
FROM php:7.3-fpm-alpine as base

WORKDIR /var/www/html

RUN set -xe \
    && apk add --no-cache bash icu-dev \
    libzip-dev \
    libzip \ 
    zlib-dev  \
    zlib \
    libpng-dev \
    libsodium-dev \
    libtool \
    libwebp-dev \
    libxml2-dev \
    libxpm-dev \
    php7-dev \
    imagemagick-dev \   
    g++ \
    gcc \
    make \  
    imagemagick \
    imagemagick-libs \
    && docker-php-ext-install zip bcmath pdo_mysql mysqli mbstring opcache pdo pdo_mysql \
    && docker-php-ext-install gd \
    && pecl install imagick apcu \
    && docker-php-ext-enable apcu opcache

EXPOSE 9000
CMD ["php-fpm", "--nodaemonize"]

# Composer Image
FROM composer:1.8 as vendor

COPY services/api/composer.json /app/composer.json
COPY services/api/composer.lock /app/composer.lock

RUN cd /app && composer install --prefer-dist --no-scripts --no-progress --no-suggest --no-interaction

# PHP APP Image

RUN mkdir -p var/log  && chmod -Rf 777 var/log

COPY ./docker/php/entrypoint*.sh /
RUN chmod +x /entrypoint*.sh

ENTRYPOINT ["/bin/sh", "/entrypoint.sh"]
EXPOSE 9000
CMD ["php-fpm", "--nodaemonize"]

# NGINX Image

FROM nginx:alpine as webservice
RUN apk add --no-cache bash coreutils grep sed
COPY ./docker/nginx/default.conf /etc/nginx/conf.d/default.conf

RUN mkdir -p /var/www/html && chmod 777 /var/www/html
COPY --from=app /var/www/html /var/www/html
COPY --from=vendor /app/vendor /var/www/html/vendor

CMD /bin/sh -c "exec nginx -g 'daemon off;'"

我的 php-fpm 容器有这个入口点：

#!/usr/bin/env bash
set -eux

cd /var/www/html

until nc -z -v -w30 ${DATABASE_HOST} ${DATABASE_PORT}
do
  echo "Waiting for database connection..."
  # wait for 5 seconds before check again
  sleep 5
done

set +e
php bin/console cache:clear
php bin/console cache:warmup
php bin/console doctrine:migrations:migrate --no-interaction

exec "$@"

但是，当我尝试运行容器并开始执行入口点脚本时，它会引发错误：

php_1 | + php bin/控制台缓存：清除 php_1 | PHP致命错误： 允许的内存大小为 2097152 字节已用尽（试图分配 32768 字节）在 /var/www/html/vendor/symfony/dependency-injection/ContainerBuilder.php 在第 129 行

我怀疑这是 var/cache 和 var/log 的权限错误，但我已经尝试过 chmod 777。我真的不知道我在哪里搞砸了。

注意：我不想将 memory_limit 增加到 -1，因为这是个坏主意，会导致我的主机死机。

非常感谢！

在你的 symfony 命令中试试这个：

php -d memory_limit=128M bin/console cache:clear
