We have historically decided to support AND TEST 3 versions of kubernetes. For that, we lagged behind in terms of client versions. Lagging behind one version allowed us, thanks to kubernetes client version skew, to support 3 versions at relatively low cost. However, maintaining 3 versions has always been a pain. For that, we pinned old versions of kubernetes clients/api and test tooling. In december 2025 community meeting, we decided to only maintain two versions: the most current one, and the previous one. This allows us to bump more regularly and be more secure. We can also more easily use dependabot this way. Signed-off-by: Jean-Philippe Evrard <open-source@a.spamming.party>
kured - Kubernetes Reboot Daemon
Introduction
Kured (KUbernetes REboot Daemon) is a Kubernetes daemonset that performs safe automatic node reboots when the need to do so is indicated by the package management system of the underlying OS.
- Watches for the presence of a reboot sentinel file e.g.
/var/run/reboot-requiredor the successful run of a sentinel command. - Utilises a lock in the API server to ensure only one node reboots at a time
- Optionally defers reboots in the presence of active Prometheus alerts or selected pods
- Cordons & drains worker nodes before reboot, uncordoning them after
