Proof of concept containerised Fabric chaincode for use with fabric-builder-k8s
Based on the token-erc-721 example in fabric-samples
See fabric-builder-k8s samples for more recent examples in Go, Java, and Node.js
The badge above should launch this contract inside a prototype Fabric dev container
Once it has started, there should be a running microfab network, which you can use to deploy the contract to as follows
Configure the peer command environment
export FABRIC_LOGGING_SPEC=INFO
export CORE_PEER_TLS_ENABLED=false
export CORE_PEER_MSPCONFIGPATH=/var/opt/hyperledger/microfab/admin-org1
export FABRIC_CFG_PATH=/var/opt/hyperledger/microfab/peer-org1/config
export CORE_PEER_ADDRESS=$(yq .peer.address ${FABRIC_CFG_PATH}/core.yaml)
export CORE_PEER_LOCALMSPID=$(yq .peer.localMspId ${FABRIC_CFG_PATH}/core.yaml)Create a chaincode-as-a-service package
~/fabric-samples/test-network/scripts/pkgcc.sh -l conga -a 0.0.0.0:9999Note: ignore the error, which is due to a known issue
Install the chaincode package
peer lifecycle chaincode install conga.tgzExport a PACKAGE_ID environment variable
export PACKAGE_ID=$(peer lifecycle chaincode calculatepackageid conga.tgz) && echo $PACKAGE_IDApprove the chaincode

Check the chaincode works!
