Hi folks. Theke Solutions has started a project some time ago, sponsored by ByWater Solutions to generate the tools and pipelines to provide a reliable Docker implementation for deploying Koha in production environments. We have just finished the housekeeping a few days ago so we are not embarrassed by our commit messages and leftovers :-D and want to propose it for community adoption anytime soon.
The project lives here for now: https://gitlab.com/thekesolutions/koha-docker What you will find there is a Docker image that can be used to run any of the different Koha services/pieces on separate containers, or all inside a single one. We aimed to target different deployment scenarios, from a small library running it on a desktop computer to a multi-cluster K8s setup. A helm chart is part of the roadmap. You will notice there are a couple issues to be addressed [1]. For instance, the shipped docker-compose.yml is outdated regarding the MySQL/MariaDB server and we definitely need more on the README. Thanks to ByWater for supporting this effort, and now that people are talking about this, let's start the conversation \o/ [1] https://gitlab.com/thekesolutions/koha-docker/-/issues El jue., 11 jun. 2020 a las 4:52, <dc...@prosentient.com.au> escribió: > Hi all, > > For a long time, I've been thinking about how Koha could scale better, and > I'm wondering what other people are thinking about this topic.
