Summary
Add a new
--internal-cidrflag that filters internal IP auto-detection by specified CIDRs. This flag can be specified multiple times.Motivation
When running Kilo with CNI plugins like Cilium, the auto-detected internal IP may incorrectly select overlay network IPs (e.g., 10.244.x.x) instead of actual node IPs (e.g., 192.168.x.x) due to lexicographic sorting in IP selection. This causes routing issues as
privIfacegets set to the wrong interface.Usage
