GitOps

The machine configs are synced every minute using comin.

To see the status:

• On machine, use comin status
• Prometheus metrics are exported on <HOST_IP>:4343/metrics

Rebuilding

Wait at most a minute for comin to pull and start a rebuild, or:

sudo nixos-rebuild switch --flake /var/lib/comin/repository/nixos#(hostname)

Note: comin can be paused using systemctl stop comin.

Testing

To test on one machine, ensure branches.testing.name is unset and push changes to a branch named testing-<HOSTNAME>.

To test changes on all machines, set branches.tesing.name to the name of the testing branch.
