22.20.2 System Administration

A configuração do Sistema Guix para todos os nossos sistemas é mantida neste repositório:

https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/

The two front-ends are berlin.scm (the machine behind ci.guix.gnu.org) and bayfront.scm (the machine behind bordeaux.guix.gnu.org, guix.gnu.org, hpc.guix.info, qa.guix.gnu.org, and more). Both connect to a number of build machines and helpers.

Caso não tenha inclusive acesso SSH à máquina, voucê pode ajudar postando patches para melhorar a configuração (pode testar isso com guix system vm). Alguns caminhos para você poder ajudar:

• Improve infra monitoring: set up a dashboard to monitor all the infrastructure, and an out-of-band channel to communicate about downtime.
• Implement web site redundancy: guix.gnu.org should be backed by several machines on different sites. Get in touch with us and/or send a patch!
• Implement substitute redundancy: likewise, bordeaux.guix.gnu.org and ci.guix.gnu.org should be backed by several head nodes.
• Improve backup: there’s currently ad-hoc backup of selected pieces over rsync between the two head nodes; we can improve on that, for example with a dedicated backup site and proper testing of recoverability.
• Support mirroring: We’d like to make it easy for others to mirror substitutes from ci.guix and bordeaux.guix, perhaps by offering public rsync access.
• Optimize our web services: Monitor the performance of our services and tweak nginx config or whatever it takes to improve it.

  There is no time constraint on this activity: any improvement is welcome, whenever you can work on it.

  Prerequisite: Familiarity with Guix System administration and ideally with the infrastructure handbook:
