By the way, I’ve raised bug 34088 to fix the slowness of the database upgrade
checks. I’ve got a workable patch there, and I’ll look at polishing it up when
I have a bit more free time.
With the database upgrade check time fixed, I think we could do an
“check_for_updates.sh” script in the Docker container entry point script.

Subject: Re: [Koha-devel] Dockerized Koha
Personally, I don’t need it at the moment, although I briefly thought I might
for one library.
Sometimes I wonder about design…
1. Would it be 1 Koha instance per container, or would it be a
multi-tenant Koha in 1 container?
2. *How would upgrades be handled?*
a. At the moment, when you install a new package, post-install hooks
upgrade the database and change some configuration files. But that wouldn’t
work if you install the package when making a new Docker image. Those hooks
wouldn’t be invoked on the production system when you launch a new container
from the new image.
i. The
solution there might be to make a new script for performing upgrades, and for
backwards compatibility it would still be called by the DEB post-install hooks,
and the Docker entrypoint.sh could call it at startup time.
1. Although if it were called at startup time, that could make startup
unnecessarily slow, since the database upgrade check is very slow even when it
has no work to do. (I have been meaning to fix that…)
2. How would configuration files be persisted?
a. If you have 1 Koha instance per container, you could just mount
individual files, but there are a lot of configuration files, so that might get
burdensome.
b. If you have multi-tenant Koha, maybe you could mount the entirety of
/etc/koha/sites. That would probably work well.
i. I don’t
think you could mount /etc/koha because a lot of those files are generated by
the koha-common package at install time, so you’d want to pick them up from the
Docker image.
4. How would other files be persisted?
a. Mount to /var/lib/koha, /var/spool/koha, /var/log/koha(?)
Anything else I’ve missed?

Hi all. We actually *have* a Docker image building pipeline [1]. If someone
wants to join the effort of publishing an official docker image, please put it
in the Roadmap wiki. That reminds me I didn't send the email about the roadmap
last week. Doing it right now.
Best regards.

And while I have a lot of experience with deploying Perl apps using
containers like Docker or Podman, I did not manage to get a (usable)
Dockerfile / docker-compose for Koha running (in a reasonable amount of
time; and then discovered koha-testing-docker for localdev..)
But I could definitely again try to spend some time on this!
