Description

Description: When using a stats_matcher inclusion_list, Envoy using the ADS variant of the xDS protocol will fail to receive cluster updates from the control-plane. After receiving an initial Cluster list, Envoy will no longer receive cluster updates. When paired with envoyproxy/go-control-plane in ADS mode, this can cause EDS updates to stall if the cluster list is later expanded.

Repro steps: A docker-compose reproduction of the issue with Envoy 1.12.2 and 1.13.0
