Hello,
If I install dejavu fonts on systems ubuntu:20.04, fedora:35,
opensuse/leap:15.4 in docker they do not install fontconfig and freetype
as dependencies.
DejaVu fonts have dependencies on fontconfig and freetype libraries on
Linux Alpine .
---------
docker run -it alpine:3.17 ash
/ # apk update
/ # apk add font-dejavu

Executing fontconfig-2.14.1-r0.trigger
Executing mkfontscale-1.2.2-r1.trigger
OK: 28 MiB in 25 packages
---------
The use case which I have is using a docker with Linux Alpine to
generate reports with Java in headless mode.
Java allows to use fonts on systems where the fontconfig is not
installed by providing paths to fonts in <jdk>/lib/fontconfig.properties
file.
Java also can be built with bundled freetype which is a subset of the
full freetype library.
Is it necessary that fonts have dependencies on fontconfig and freetype
libraries in Alpine Linux?
Thanks,
Alexander.

freetype is merely a dependency of fontconfig in this case
>>> Is it necessary that fonts have dependencies on fontconfig and freetype > libraries in Alpine Linux?
yes, as normally using the fonts generally requires it.
i suppose it's not impossible to not depend on it paired with any fonts
directly, but strictly speaking there is generally no difference, except in
your special usecase. you'd probably say the same goes for mkfontscale?

Yes. The general question is that fonts on Alpine Linux has more
dependencies than fonts on other systems.
For example, if I use ubuntu:20.04, dejavu fonts depend only on
fonts-dejavu-core and fonts-dejavu-extra
---------
docker run -it ubuntu:20.04 bash
apt update
apt install fonts-dejavu
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following additional packages will be installed:
fonts-dejavu-core fonts-dejavu-extra
The following NEW packages will be installed:
fonts-dejavu fonts-dejavu-core fonts-dejavu-extra
0 upgraded, 3 newly installed, 0 to remove and 4 not upgraded.
Need to get 2996 kB of archives.
After this operation, 10.5 MB of additional disk space will be used.
---------
The aim is to use a docker image with Java as small as possible.
What is the right way to setup Alpine Linux docker with fonts and
without additional dependencies for my use case?
My be fonts can be just copied during docker image creation instead of
just font installation from packages?
Thanks,
Alexander.

merely dropping the dependencies could be looked at by someone if they wanted,
i don't have the energy currently , but for your usecase:
- exactly that, just copy what you want.
- use:
$ apk add -t mkfontscale
$ apk add -t fontconfig
(note individual commands with nothing else)
this is a hack(!) that creates a virtual package with no dependencies with a
pkgver of the current date, so it will then uninstall the real ones that exist
(since the dependency is satisfied via name only, and this virtual has the
highest version). you end up with no dependencies.

Thank you. This works for my case.
