Chaincode Lifecycle

Environment Varibles

• FABRIC_CFG_PATH path of configtx.yaml file

• CORE_PEER_LOCALMSPID ID of peer to be accessed

• CORE_PEER_ADDRESS IP/FQDN+PORT of peer to be accessed

• CORE_PEER_TLS_ENABLED (required only for TLS)

• CORE_PEER_TLS_CERT_FILE

• CORE_PEER_TLS_KEY_FILE

• CORE_PEER_TLS_ROOTCERT_FILE

• CORE_PEER_MSPCONFIGPATH

Steps

• packaging chaincode （make *.tar.gz）

peer lifecycle chaincode package

• installing chaincode （upload chaincode to peer）

peer lifecycle chaincode install

• getting package ID

peer lifecycle chaincode queryinstalled

• sign chaincode

peer lifecycle chaincode approveformyorg

• check chaincode status

peer lifecycle chaincode checkcommitreadiness

• commit chaincode peer lifecycle chaincode commit

Example

#1.0 switch to PEER0@ORG1
#1.1. package
peer lifecycle chaincode package tmp/${CC_LABEL}.tar.gz --path ${CC_PATH} --lang $CC_LANG --label ${CC_LABEL}
#1.2. install
peer lifecycle chaincode install tmp/${CC_LABEL}.tar.gz
#1.3. get packageID
peer lifecycle chaincode queryinstalled --output json | jq -r '.installed_chaincodes[] | select(.label == env.CC_LABEL) | .package_id'
#1.4. sign-ORG1
peer lifecycle chaincode approveformyorg \
-o ${ORDERER_ADDRESS} --ordererTLSHostnameOverride orderer.example.com --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA \
--channelID $CHANNEL_NAME --name ${CC_NAME} --version ${CC_VERSION} \
--init-required --package-id ${PACKAGE_ID} --sequence $CC_SEQ --waitForEvent \
--signature-policy "$CC_POLICY"

#2.0 switch to PEER0@ORG2
#2.1. package
peer lifecycle chaincode package tmp/${CC_LABEL}.tar.gz --path ${CC_PATH} --lang $CC_LANG --label ${CC_LABEL}
#2.2. install
peer lifecycle chaincode install tmp/${CC_LABEL}.tar.gz
#2.3. get packageID
peer lifecycle chaincode queryinstalled --output json | jq -r '.installed_chaincodes[] | select(.label == env.CC_LABEL) | .package_id'
#2.4. sign-ORG2
peer lifecycle chaincode approveformyorg \
