Vips missing

[typhoon2099]

vips-dev seems to be installed in the Docker image (jekyll/jekyll:latest) but it's not available to me. I've tried running which vips but I get no response, and jekyll_picture_tag which requires it in version 2.0.0 is failing because it can't run it either.

EDIT: I have confirmed it is installed using apk list --all | grep vips, which returns:

vips-8.8.4-r0 x86_64 {vips} (LGPL-2.1-or-later) [installed]
vips-dev-8.8.4-r0 x86_64 {vips} (LGPL-2.1-or-later) [installed]

Unfortunately, none of the packages vips nor vips-dev contains a vips binary and no build is done during docker image generation. You'll find the binary in vips-tools.
=> To maintainers : So why not install vips-tools directly ?

PS: Same for imagemagick-dev which do not contains any binary and is not built.
=> To maintainers: Binaries are in the imagemagick package.
