I just tried minideb, the resulting image weigh 1.1GB, right between
debian:buster-slim and debian:buster
I did not found a free plan for quay.io (only a 30-day free trial). Does
it have one ?

This is fantastic Julian! The only thing I can contribute that hasn't
already been said by you or David is to suggest taking a look at MiniDeb
as a base image ( https://github.com/bitnami/minideb ). I would also
suggest using quay.io <http://quay.io> to build and host your Docker
images, as it has built in security scanning. I prefer minimal install
images not for size reduction ( though it is nice ), but for the smaller
attack surface they provide. Fewer things installed means fewer exploits
available!

Hi all,
I've been playing with docker lately, and I tried to build a minimal
docker image for Koha. Here are the results.
My goals were:
* Install only required "things" to get Koha up and running, and
nothing
else (no testing or dev tools),
* No external dependencies except CPAN
* Follow Docker best practices as much as possible
The resulting images are here:
https://hub.docker.com/repository/docker/julianmaurice/koha
and the Dockerfiles are here:
https://github.com/jajm/koha-docker
A few things worth mentioning:
* I tried to build the smallest image possible by using alpine or perl
slim images at first but it was not that great, because the perl
version
shipped with those images is missing some libs, which cause
MARC::Charset to build a database of several hundreds MBs (which is
only
5MBs with a standard perl version). So I chose a more standard image
(debian:buster) as base.
* Koha doesn't work well when running with a perl version different
than
the system perl installed in /usr/bin/perl. For example, the
updatedatabase doesn't work when called from the web installer. This is
because Perl scripts are called directly as executable files, and
shebangs contain '/usr/bin/perl'. Same problem from
misc/translator/translate which calls tmpl_process3.pl
<http://tmpl_process3.pl>.
* I tried to make the Koha installation as self-contained as possible.
Almost everything is installed as a non-root user in /home/koha,
including Perl dependencies.
* It doesn't need a reverse proxy such as apache or nginx. The
necessary
URL rewriting is handled in PSGI file. The container expose two ports,
one for intranet, the other one for OPAC.
* Each Perl dependency is installed in its latest version, so expect
things to break. I can only confirm that the webinstaller, basic
cataloguing and search/indexation work. I did not test anything else.
* There are docker-compose.yml files in the github repository to get
Koha running quickly with mariadb, memcached and elasticsearch.
* Zebra is not installed
* Images weigh ~1.15GB uncompressed (koha sources included)
If you made it this far, thanks for reading :)
And if you want to use these docker images, you should start by reading
