Migration and Optimization 2024/2025

We're planning to consolidate services into a standard deployment model, consolidate external services, and maybe add some new ones.

Next Milestones

• Get server stable
• Setup useable pretix + authentik + nextcloud calender

Ideas and Notes

Consolidate:

• Wiki: Containerize => Challenges: php modules; updating php/wiki; ggf. make it easier to include the plugins (maybe php compose module handling)
• Mailsystem: ??

Externally hosted, and to be transfered into MuMaLab Infrastructure

• Tickets (https://tickets.mumalab.org/courses/)
• Calendar -> Google Calendar -> NextCloud
• ToolJet (via OpenUnitState)

Planned Services

• NextCloud
• evtl Ticket System
• Single Sign On: e.g. login to wiki either locally or via SSO. Later only SSO. Can be used e.g. for nextcloud or other services as well

Details unclear

• InfoBeamer

Mailsystem

Should support migrating of existing data and maillinglists

• https://docs.mailcow.email/#what-is-mailcow-dockerized => seems to work with postfix and integration with mailman 3 seems to be possible
• Docker Mailserver

 * Mailman supported via addon container, but very very old - docker-mailman3

• poste.io
• Mailu
• MailInABox - not dockerized

Lightburn VM

2. Licence for lightburn is already available. Would be nice to give members the chance to prepare Laser stuff remote and just come to the lab to laser.

Challenges: No Linux support https://forum.lightburnsoftware.com/t/linux-support-to-end-after-v1-7/144605; exposing remote desktop in secure way

Remote Systems?

SSO

IDPs

1. Option: Authentik
2. Option: https://git.cccv.de/uffd/uffd
3. Option: ...?
