How to watch the log file of the "orderer" Container?

The "orderer" Container plays an important role in a Hyperledger Fabric network. You can follow this tutorial to watch its log file:

1. Set up a new terminal on the hosting system to follow the log file of the "orderer" container:

$ docker logs -f orderer.example.com
[localconfig] completeInitialization -> INFO 001 Kafka.Version unset, setting to 0.10.2.0
[orderer.common.server] prettyPrintStruct -> INFO 002 Orderer config values:
        General.LedgerType = "file"
        General.ListenAddress = "0.0.0.0"
        General.ListenPort = 7050
        General.TLS.Enabled = true
        General.TLS.PrivateKey = "/var/hyperledger/orderer/tls/server.key"
        General.TLS.Certificate = "/var/hyperledger/orderer/tls/server.crt"
        General.TLS.RootCAs = [/var/hyperledger/orderer/tls/ca.crt]
        ...

[orderer.common.broadcast] Handle -> WARN 032 Error reading from 192.168.1.7:58476: \
   rpc error: code = Canceled desc = context canceled
[comm.grpc.server] 1 -> INFO 033 streaming call completed \
   grpc.service=orderer.AtomicBroadcast \
   grpc.method=Broadcast grpc.peer_address=192.168.1.7:58476 \
   error="rpc error: code = Canceled desc = context canceled" \
   grpc.code=Canceled grpc.call_duration=1m31.930790373s

2. Use another terminal to query the chaincode:

$ docker exec -it cli bash

bash-4.4# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
90

No new message printed on the orderer log window.

3. Use another terminal to invoke the chaincode:

bash-4.4# peer chaincode invoke -o orderer.example.com:7050 --tls true \
   --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto\
   /ordererOrganizations/example.com/orderers/orderer.example.com/msp\
   /tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc \
   --peerAddresses peer0.org1.example.com:9051 --tlsRootCertFiles \
   /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations\
   /org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
   --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles \
   /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations\
   /org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
   -c '{"Args":["invoke","a","b","10"]}'

[chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200

Two new messages printed on the orderer log window, one warning and one information:

[orderer.common.broadcast] Handle -> WARN 034 Error reading from 192.168.1.7:36600: \
   rpc error: code = Canceled desc = context canceled
   
[comm.grpc.server] 1 -> INFO 035 streaming call completed \
   grpc.service=orderer.AtomicBroadcast grpc.method=Broadcast \
   grpc.peer_address=192.168.1.7:36600 error="rpc error: code = Canceled desc = context canceled" \
   grpc.code=Canceled grpc.call_duration=64.329479ms
