In split service mode, and during periods of inactivity, the gRPC connections to the databroker may fall idle. Some network firewalls may eventually time out an idle TCP connection and even start dropping subsequent packets once connection traffic resumes. Combined with Linux default TCP retransmission settings, this could cause a broken connection to persist for over 15 minutes. In an attempt to avoid this scenario, enable TCP keepalive for outbound gRPC connections, matching the Go standard library default settings for time & interval: 15 seconds for both. (The probe count does not appear to be set, so it will remain at the OS default.) Add a test case exercising the BuildClusters() method with the default configuration options, comparing the results with a reference "golden" file in the testdata directory. Also add an '-update' flag to make it easier to update the reference golden when needed: go test ./config/envoyconfig -update |
