[Reserved IP][Feature request] The controller should wait Control plane is aware of IP change before applying the label

[sogos]

Hello,

I am using the reserved ip feature and i observe the label reserved-ip=true is applied 2 or 3 minutes before the reserved IP is actually installed on the node.

I use this label to authorize my pods to deploy on these nodes and I would like Kubernetes to be aware of the change of IP before it deploys

Ideally a pending status, then a done status :)

Thanks

You means in a kubectl get node ?
Instance call to set the ip is done before setting the label and instance api take less than 30s to update the NAT.

I don't know exactly but the Node.Address.ExternalAddress is not updated before several minutes.
My goal is to notify the managed Load Balancer as soon as possible of the Node Ip change.

Probably, the behavior is good and I need to implement something else

Edit :

I writed a small program in go to monitor timings:
