Invoke Operation on Chaincode Container

Q

Which chaincode container runs the chaincode invoke operation?

A

The chaincode "mycc" instance is configured in the BYFN (Build Your First Network) to run in both chaincode containers when one of their peers receives the "Invoke" call.

1. Set up a terminal on the hosting system to follow the log file of the chaincode container linked to "peer0.org1":

$ docker ps --all | grep dev-peer0.org1
cc7aeb60bb85        dev-peer0.org1.example.com-mycc-2.0-04da...

$ docker logs --tail 10 -f cc7aeb60bb85

2. Set up another terminal on the hosting system to follow the log file of the chaincode container linked to "peer0.org2":

$ docker ps --all | grep dev-peer0.org2
5e2d37a1099f        dev-peer0.org2.example.com-mycc-2.0-03c5...

$ docker logs --tail 10 -f 5e2d37a1099f

3. Invoke the chaincode instance from peer0.org1:

$ docker exec -it cli bash

bash-4.4# echo $CORE_PEER_ADDRESS
peer0.org1.example.com:7051

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

The same message comes out from both chaincode containers linked to peer0.org1 and peer0.org2:

ex02 Invoke
Aval = 70, Bval = 230
