Highlight duplicate IP addresses #2198

Open bboreham opened 7 years ago

bboreham commented 7 years ago

I just spent ~3 days hunting down an issue where a bridge and a pod had got the same IP address. So proposing a Scope feature where this would be highlighted.

None of the surrounding infrastructure - Weave IPAM, Kubernetes - was aware of the duplication; it was only on the devices themselves.

This would require retrieving the IP address of all interfaces (which I don't think we do right now).

Approximately the same approach as at https://github.com/weaveworks/scope/issues/2164#issuecomment-275760465, plus bridges in the host namespace
