We’re releasing an optional feature where it’s possible to assign Elastic IPs to nodepools. This can be useful for whitelisting purposes. For example when nodes, running in public subnets, need to connect to services behind enterprise firewalls.
When enabled, a node will search for available EIPs with a defined tag and try to assign it. If assignment fails, these nodes will become tainted with node.kubernetes.io/eip-unavailable:NoSchedule. We have also alerts in place to notify you and us when this happens.
If you have a use case for this feature, get in touch with your lead engineer for the details and setup.
