First meeting of the (revamped) infra team.

Participants: delroth, hexa, raitobezarius, vcunat, zimbatm

[zimbatm] Presentation

  • At NixCon, we added new people to the team, but we were not able to give space to those new people, with this in mind, I would like to dedicate one hour per week or two weeks where I can unblock the infrastructure matters.
  • I don’t know what people are interested in, I believe this is a volunteer ecosystem and you should work on what you would like to work on.
  • We have big challenges in front of us, e.g. the cache situation, with a new team, maybe we can tackle those bigger challenges.

Round of intros

Skipped in these edited notes.

[raito] Recommending hexa for infra-core

  • Consensus: yes please.
  • [zimbatm] Done.
  • delroth/vcunat to assist with onboarding, provision access, etc.

[delroth] Matrix Homeserver situation

  • EMS is dropping legacy plans after 2024-01-17
  • We are getting dropped.
  • We need to react but Graham, owner of the EMS account, is not reacting.
  • The problem is not the cost but access to the account.
  • delroth/hexa are in favor of self-hosting.
    • But we need the database dump from EMS.
    • hexa to prepare the config for this, delroth can act as backup/fallback.
  • Fallback: we can always pay the $1200 (excl. VAT) for renewing the 1 year plan.

[hexa] Moving NGI out of nixos-org-configurations

  • Goals: unblock ngi0 maintainers, less consumption of our review bandwidth.
  • Should we move them to a new repo?
    • Either in the nixos GitHub org or the ngi-nix org.
  • Action item: let's ask them!

Builders

  • Context: various cost reduction efforts need to happen on the Hydra/ofborg builders infra.
  • There might be the possibility to get Hetzner to sponsor one more machine.
  • [delroth] Pretty sure we are not using our build resources efficiently as it is (queue-runner bottleneck)
  • [vcunat] xz compression is the main problem
  • [zimbatm] We should properly analyze where the bottlenecks are.

Backups

  • We are not doing proper backups of the NixOS infra.
  • There is an rsync.net account where the Hydra database gets backed up to, at least.
  • Julien's vaultwarden PR is currently blocked by this, we're getting backup storage space from Hetzner (storage boxes).
