Support for wkhtmltopdf

A working solution to add wkhtmltopdf to the existing PHP container is to install it after the container got started:

apk add --no-cache xvfb ttf-freefont fontconfig dbus
apk add qt5-qtbase wkhtmltopdf --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/testing/ --allow-untrusted
mv /usr/bin/wkhtmltopdf /usr/bin/wkhtmltopdf-origin

Then add a new file /usr/bin/wkhtmltopdf with the following content and make it executable:

#!/usr/bin/env sh

Xvfb :0 -screen 0 1024x768x24 -ac +extension GLX +render -noreset &
DISPLAY=:0.0 wkhtmltopdf-origin $@
killall Xvfb

When using the Drupal module print then go to admin/config/user-interface/print/pdf/wkhtmltopdf and remove the options --footer-font-size 7 --footer-right '[page]' because they don't work in the unpatched QT version.

wkhtmltopdf was moved from testing to community. This is what I ran today to create my docker image:

RUN apk add --update --no-cache \
    xvfb dbus libgcc libstdc++ libx11 glib libxrender libxext libintl \
    libcrypto1.0 libssl1.0 \
    fontconfig ttf-dejavu ttf-droid ttf-freefont ttf-liberation ttf-ubuntu-font-family

RUN apk add qt5-qtbase --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/testing/ --allow-untrusted \
	&& \
	apk add wkhtmltopdf --no-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/community/ --allow-untrusted \
	&& \
    mv /usr/bin/wkhtmltopdf /usr/bin/wkhtmltopdf-origin && \
    echo $'#!/usr/bin/env sh\n\
Xvfb :0 -screen 0 1024x768x24 -ac +extension GLX +render -noreset & \n\
DISPLAY=:0.0 wkhtmltopdf-origin $@ \n\
killall Xvfb\
' > /usr/bin/wkhtmltopdf && \
    chmod +x /usr/bin/wkhtmltopdf

@brandonbest thanks for your comment. Our composer plugin also comes with a built-in solution (see the commits above) and the main task is done by this script which is pretty similar to what you've posted.

Instead of building this into the php container by default we allow that to be configured in composer.json such that this script gets called when the container starts up only if the current project really requires wkhtml.

Why there is unpatched QT version?

@Mykola-Veriga what do you mean by that question?

There we have /usr/bin/wkhtmltopdf unpatched QT version.

But we can install something like that

$ /usr/bin/wkhtmltopdf-origin --version
wkhtmltoimage 0.12.5 (with patched qt)

Then the footer-html option will works.

Yes, I remember we had experimented with the unpatched version but ran into other difficulties which I can't recall in detail. But if you wanted to provide an MR to improve this, then you're more than welcome. But you should start a new issue for that, because this one is over one year old and long closed.

I didn't have enough time to resolve the issue in the right way. I used this quick solution
