Web Infrastructure

Some documentation on MuMaLab's web infrastructure stuff.

Current Tasks

Checkout: Working Group IT

Hosts

We currently have 3 VMs at Hetzner:

• mars.munichmakerlab.de (Mars)
• jupiter.munichmakerlab.de
• saturn.munichmakerlab.de

Saturn

• docker containers are started via systemd or via docker compose (configs in /data/ path) => target everything with docker compose with separated /data/ and /config/ folder.
• cronjob added for cleanup of old docker images
• docker deamon resource limit via systemd slice (/etc/systemd/system/docker.slice)
• Firewall: ufw => check via sudo ufw status verbose (does not include docker. This would need addtional hacks like this, but it had no benefits so far with the reverse proxy we already use)

Maintenance

We currently have a bit of a spam problem, easiest way to fix it currently is to clean them up in the database directly.

update mw_account_requests set acr_rejected = DATE_FORMAT(NOW(),"%Y%m%d%H%i%S"), acr_user = 1, acr_comment = "Spam, no confirmed mail address", acr_deleted = 1 where acr_email_authenticated is null and acr_rejected is null and acr_registration < now() - interval 7 day;

update mw_account_requests set acr_rejected = DATE_FORMAT(NOW(),"%Y%m%d%H%i%S"), acr_user = 1, acr_comment = "Spam", acr_deleted = 1 where acr_rejected is null and acr_registration < now() - interval 7 day;
