我是docker的新手，我正在尝试运行这个dockerfile
FROM php:latest
RUN apt-get update && apt-get install -y libmcrypt-dev \
mysql-client libmagickwand-dev --no-install-recommends
RUN pecl install imagick
RUN docker-php-ext-enable imagick
RUN docker-php-ext-install pdo_mysql
RUN docker-php-ext-install zip
WORKDIR /app
但是我得到了这个错误
FROM php:latest
RUN apt-get update && apt-get install -y libmcrypt-dev \
mysql-client libmagickwand-dev --no-install-recommends
RUN pecl install imagick
RUN docker-php-ext-enable imagick
RUN docker-php-ext-install pdo_mysql
RUN docker-php-ext-install zip
WORKDIR /app
我应该使用什么来代替mysql客户端？

通常是mariadb客户端现在，我认为在PHP7.1之后，他们更改了基础映像的sql版本
