Docker - PHP 7.2 FPM Alpine - Imagick

Question

I'm using Docker image php:7.2-fpm-alpine as base image with following command to install Imagick:

RUN apk add --update --no-cache autoconf g++ imagemagick-dev libtool make pcre-dev \
    && pecl install imagick \
    && docker-php-ext-enable imagick \
    && apk del autoconf g++ libtool make pcre-dev

Everything went fine with build and I have php7.2 with Imagick but it cannot be used because of following error:

UnableToOpenConfigureFile `coder.xml' @ warning/configure.c/GetConfigureOptions/714

I'm trying to fix this for two hours. I tried with adding XML libraries without any luck. Any ideas?

Solution

The files you are missing are in the imagemagick package, which you also need to apk add explicitly. The dependencies for imagemagick-dev do not pull it in.
