Docker PHP7 CLI Debian Buster 如何安装软件包 php-imagick？

Question

我有一个 PHP-CLI Docker image of Debian Buster and would like to install php-imagick 包，但有命令：

Docker 文件：

RUN apt-get install -y php-imagick

我得到一个错误：

Package php-imagick is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package 'php-imagick' has no installation candidate

运行之前：

RUN apt-get update -y && apt-get upgrade -y

没有帮助。

怎么没有php-imagick的候选包？
如何为此 PHP Docker image 安装和启用 imagick 扩展？

要复制问题的 Dockerfile：

FROM php:7.3-buster

RUN apt-get update -y && apt-get upgrade -y
RUN apt-get install -y php-imagick

构建命令

docker build --tag testimage .

除非您有充分的理由不这样做，否则使用 https://deb.sury.org/ 中的软件包可能是个好主意。以下似乎有效：

FROM debian:buster-slim

USER root

# Get Debian up-to-date
RUN apt-get update -qq \
    && DEBIAN_FRONTEND=noninteractive apt-get install -y git \
    mariadb-client wget curl \
    ca-certificates lsb-release apt-transport-https gnupg bsdmainutils

RUN echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | tee -a /etc/apt/sources.list.d/php.list \
    && curl https://packages.sury.org/php/apt.gpg | apt-key add - \
    && apt-get update -qq \
    && DEBIAN_FRONTEND=noninteractive apt-get install -y php7.3 php7.3-common php7.3-cli \
    php7.3-mysql php7.3-curl php7.3-xml php7.3-mbstring \
    php7.3-intl php7.3-redis php7.3-zip \
    php7.3-imagick supervisor
