Bug Reporting

Expected Behavior

Applicable new nodes should get the shared IP assigned when they join the cluster if a cilium BGP Load Balancer exists.

Actual Behavior

New nodes are not getting the shared IP assigned.

Steps to Reproduce the Problem

1. Deploy CCM with cilium BGP load balancing enabled
2. Deploy a sample deployment such as nginx
3. Create a service of type LoadBalancer to expose the sample deployment
4. Scale up the cluster to add a new node
5. Observe the new node does not get the shared IP attached to it in the Linode Cloud Manager.
