* Use RandomizedDelaySec to spread out control certificates renewal plane If the number of control plane node is superior to 6, using (index * 10 minutes) will fail (03:60:00 is not a valid timestamp). Compared to just fixing the jinja expression (to use a modulo for example), this should avoid having two control planes certificates update node being triggered at the same time. * Make k8s-certs-renew.timer Persistent If the control plane happens to be offline during the scheduled certificates renewal (node failure or anything like that), we still want the renewal to happen. |
