wkhtmltopdf with php:8-fpm-alpine

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:

Dockerfile...

FROM php:8-fpm-alpine
...
RUN apk add xvfb libfontconfig wkhtmltopdf

error:

ERROR [ 8/13] RUN apk add --no-cache wkhtmltopdf                                                                                                   2.1s

executor failed running [/bin/sh -c apk add --no-cache wkhtmltopdf]: exit code: 1
ERROR: Service 'php' failed to build : Build failed

I tried including contents from following repository, but i think its way too much work for 1 package, and it breaks in build process: https://github.com/alloylab/Docker-Alpine-wkhtmltopdf

Any help would be appreciated.

Solution

  • I faced a similar problem with php:7.4-fpm-alpine image.

    It seems like wkhtmltopdf is missing in Alpine v.3.15, but it is available in v.3.14.

    Try to change

    FROM php:8-fpm-alpine

    to

    FROM php:8-fpm-alpine3.14
