Hi All,
trying to get GNMI telemetry from Telegraf in docker. GRPC host available from docker via nc with grpc port destination. But no actual communication to grpc host detected in tcpdump from telegraf and constantly got an error:
2021-09-09T16:28:41Z E! [inputs.gnmi] Error in plugin: failed to setup subscription: rpc error: code = Unavailable desc = connection error: desc = “transport: Error while dialing failed to do connect handshake, status code: 503 Service Unavailable”
The same config from host service telegraf works well. But need to do the same from docker.
Please help to troubleshoot.
Config:
