Walkthrough

The OVN node and master DaemonSets now use startup probes to check for /etc/cni/net.d/10-ovn-kubernetes.conf. Each probe runs every five seconds and allows 36 failures.

Changes

OVN startup probes

Layer / File(s)	Summary
CNI configuration startup checks `assets/components/ovn/multi-node/node/daemonset.yaml`, `assets/components/ovn/single-node/master/daemonset.yaml`	The `ovnkube-node` and `ovnkube-master` containers now use an exec-based `startupProbe` that checks for the CNI configuration file. Existing readiness probe configuration remains unchanged.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to ae79e

A restarted OVN pod can appear started and ready while its node initialization is still running. Remove the stale CNI file during startup before merging.
