Cluster discovery service |
|
========================= |
|
|
|
The cluster discovery service (CDS) is an optional API that Envoy will call to dynamically fetch |
|
cluster manager members. Envoy will reconcile the API response and add, modify, or remove known |
|
clusters depending on what is required. |
