Question

我整天都在尝试将一些PHP扩展安装到定制的docker映像中（基于官方php：7.1.21-fpm-alpine3.8映像），但是没有成功。我真的不知道自己在做什么错，因为我过去能够做同样的事情。

当我运行docker-compose up时，似乎图像（php-fpm，nginx和mysql）已正确构建，并且3个docker容器正在运行。

但是，当我检查phpinfo文件时，可以看到未加载扩展名。（pdo_mysql，zip，imap和xdebug）

当我进入php-fpm容器并检查/usr/local/etc/php/conf.d目录时，我可以看到所有这些扩展的ini文件：

docker-php-ext-imap.ini
docker-php-ext-pdo_mysql.ini
docker-php-ext-xdebug.ini
docker-php-ext-zip.ini
my-firm.ini

phpinfo还通知我“扫描此目录以查找其他.ini文件”为空（无值）

app.dockerfile：

FROM php:7.1.21-fpm-alpine3.8

RUN rm -rf /var/cache/apk/* && \
    rm -rf /tmp/*

编辑：令我更加陌生的是，我在docker-compose文件中创建了一个附加服务，而dockerfile看起来大致相同。当我检查该新服务的phpinfo文件时，它确实加载了pdo_mysql吗？

app.dockerfile（新服务）：

FROM php:7.1.21-fpm-alpine3.8

# Clean & update package manager
RUN rm -rf /var/cache/apk/* && \
    rm -rf /tmp/*

RUN apk update

# Install tools
RUN apk add --no-cache ${PHPIZE_DEPS}

# Install PHP extensions
RUN docker-php-ext-install pdo pdo_mysql

RUN pecl install xdebug \
    && docker-php-ext-enable xdebug

# Copy configuration file(s)
COPY php-ini/my-firm.ini /usr/local/etc/php/conf.d/my-firm.ini

# Set workdir
WORKDIR /var/www

Answer 1

我发现了问题：我正在将docker.compose.yml文件中的.env文件加载到该.env文件中的值包含双引号。删除引号即可解决此问题。

未使用官方PHP docker映像安装/加载/启用PHP扩展
