k8s.ServiceSpec.externalTrafficPolicy property

Denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints.

Signature:

externalTrafficPolicy?: string;

Remarks

"Local" preserves the client source IP and avoids a second hop for LoadBalancer and Nodeport type services, but risks potentially imbalanced traffic spreading. "Cluster" obscures the client source IP and may cause a second hop to another node, but should have good overall load-spreading.
