title: wkhtmltopdf with php:8-fpm-alpine
body: <p>I have an existing php:8-fpm-alpine Dockerfile, and i need to add WKHTMLTOPDF package. Is that even possible. I tried using following dockerfile, but i get following error log:</p>
  <p>Dockerfile...</p>
  <pre><code>FROM php:8-fpm-alpine
  ...
  RUN apk add xvfb libfontconfig wkhtmltopdf
  
  </code></pre>
  <p>error:</p>

  <p>I tried including contents from following repository, but i think its way too much work for 1 package, and it breaks in build process:
  <a href="https://github.com/alloylab/Docker-Alpine-wkhtmltopdf" rel="nofollow noreferrer">https://github.com/alloylab/Docker-Alpine-wkhtmltopdf</a></p>
  <p>Any help would be appreciated.</p>
