How to test hyperledger fabric V1.0 chaincode from CLI

How to test your chaincode from Vagrant :

You wrote some chaincode on Fabric V1.0 and now you wanted to test your chaincode with simple of steps of creating a channel configuration , create channel and join channel ...?

Follow are the instructions:

---

Pre-requisites:

mkdir -p $GOPATH/src/github.com/hyperledger

cd $GOPATH/src/github.com/hyperledger

git clone https://github.com/hyperledger/fabric.git

rm -rf /var/hyperledger/*

Build native binaries

cd fabric/devenv

vagrant up && vagrant ssh

cd $GOPATH/src/github.com/hyperledger/fabric

make peer orderer

NOTE: If required do make clean and build the binaries

---

Vagrant Terminal Tab 1:

Start the Orderer

ORDERER_GENERAL_GENESISPROFILE=SampleSingleMSPSolo orderer

---

Vagrant Terminal Tab 2:

Start the peer

peer node start

---

Vagrant Terminal Tab 3:

This uses chaincode example program example02 Install chaincode on the peer

peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

---

Generate channel configuration (transaction)

configtxgen -channelID myc -outputCreateChannelTx myc.tx -profile SampleSingleMSPChannel

---

Create channel

peer channel create -o 127.0.0.1:7050 -c myc -f myc.tx -t 10

---

Join channel

peer channel join -c myc -f myc.block

---

Instantiate chaincode

peer chaincode instantiate -o 127.0.0.1:7050 -C myc -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}'

After succesful chaincode instantiation, you would see chaincode container comes up. docker ps

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
ba2746fd32bf        dev-jdoe-mycc-0    "chaincode -peer.a..."   6 seconds ago       Up 5 seconds                            dev-jdoe-mycc-0

---

Invoke

Issue an invoke to move "10" from "a" to "b":

peer chaincode invoke -o 127.0.0.1:7050 -C myc -n mycc -c '{"Args":["invoke","a","b","10"]}'

Wait a few seconds for the operation to complete

---

Query

Query for the value of "a"

peer chaincode query -n mycc -c '{"Args":["query","a"]}'

---

cleanup

Don't forget to clear ledger after each run!

rm -rf /var/hyperledger/*

And may be chaincode containers(optional)

docker rm -f $(docker ps -aq)

docker rmi -f $(docker images | grep "dev-jdoe" | awk '{print $3}')
