How to test marbles02 sample chaincode from vagrant environment

Execution 2 : Sample chaincode marbles02

Install

peer chaincode install -n marbles -v 1 -p github.com/hyperledger/fabric/examples/chaincode/go/marbles02

Instantiate

peer chaincode instantiate -o 127.0.0.1:7050 -n marbles -v 1 -p github.com/hyperledger/fabric/examples/chaincode/go/marbles02 -c '{"Args":[""]}'

After succesful chaincode instantiation , you would see a chaincode container coming up

CONTAINER ID        IMAGE                COMMAND                  CREATED             STATUS              PORTS               NAMES

Invoke

  • Create 3 marbles
peer chaincode invoke -o 127.0.0.1:7050 -n marbles -c '{"Args":["initMarble","marble1","blue","35","tom"]}' 
peer chaincode invoke -o 127.0.0.1:7050 -n marbles -c '{"Args":["initMarble","marble2","red","50","tom"]}'
peer chaincode invoke -o 127.0.0.1:7050 -n marbles -c '{"Args":["initMarble","marble3","blue","70","tom"]}'
  • Transfer marble2 from tom to Jerry
peer chaincode invoke -o 127.0.0.1:7050 -n marbles -c '{"Args":["transferMarble","marble2","jerry"]}'
  • Transfer blue color marble to Jerry
peer chaincode invoke -o 127.0.0.1:7050 -n marbles -c '{"Args":["transferMarblesBasedOnColor","blue","jerry"]}'
  • Delete marble1
peer chaincode invoke -o 127.0.0.1:7050 -n marbles -c '{"Args":["delete","marble1"]}'

Query

peer chaincode query -n marbles -c '{"Args":["readMarble","marble1"]}'
peer chaincode query -n marbles -c '{"Args":["getMarblesByRange","marble1","marble3"]}'
peer chaincode query -n marbles -c '{"Args":["getHistoryForMarble","marble1"]}'
