Java chaincode cheatsheet

Attempting to figure out how to do stuff with Java chaincode on Fabric. Don't try this at home!

The following is based on Java chaincode generated using generator-fabric running in a fabric-devenv Vagrant environment.

v1.4???

export CORE_PEER_ADDRESS=0.0.0.0:7051
export CORE_PEER_LOCALMSPID=Org1MSP
export CORE_PEER_MSPCONFIGPATH=/home/vagrant/test-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp

peer chaincode install -l java -n mycc -v v1 -p <path_to_chaincode>

peer chaincode instantiate -o 0.0.0.0:7050 -C mychannel -c '{"Args":[]}' -P 'OR ("Org1MSP.member")' -n mycc  -v v1

With private data config: --collections-config <path_to_config>

peer chaincode invoke -C mychannel -o 127.0.0.1:7050 -n mycc -c '{"Args":["CreateAsset", "1"]}'

v2???

docker exec -it cli bash
peer lifecycle chaincode package pc0.tar.gz --path /opt/gopath/src/github.com/contracts/java-contract/ --lang java --label pc_0
peer lifecycle chaincode install pc0.tar.gz
export CC_PACKAGE_ID=$(peer lifecycle chaincode queryinstalled 2>&1 | awk -F "[, ]+" '/Label: /{print $3}') && echo $CC_PACKAGE_ID
peer lifecycle chaincode approveformyorg --channelID mychannel --name pc_0 --version 0.0.3 --package-id $CC_PACKAGE_ID --sequence 1 --waitForEvent
peer lifecycle chaincode commit -o orderer.example.com:7050 --channelID mychannel --name pc_0 --version 0.0.3 --sequence 1 --waitForEvent
peer chaincode invoke -o orderer.example.com:7050 --channelID mychannel --name pc_0 -c '{"Args":["arg1","arg2"]}'

Cheat Sheet for sequence of commands for v2.0 lifecycle and byfn (from Matthew White!)

docker kill $(docker ps -q) && docker rm $(docker ps -aq)  
docker rmi $(docker images dev-* -q) --force
docker volume prune -f && docker network prune -f
./byfn.sh generate
./byfn.sh restart
