E：包"mysql-client"在 dockerfile 执行时没有安装候选

Question

我是docker的新手，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

但是我收到这个错误

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-client？

现在通常是mariadb-client，我认为在过去的PHP 7.1+中，他们更改了基础图像的sql版本
