## 1. 釋義 將指定的鏈碼部署到網絡上。 ## 2. 使用方法 ``` ~$ peer chaincode instantiate [flags] ``` ## 3. 命令標志 ``` -C, --channelID string The channel on which this command should be executed --collections-config string The fully qualified path to the collection JSON file including the file name --connectionProfile string Connection profile that provides the necessary connection information for the network. Note: currently only supported for providing peer connection information -c, --ctor string Constructor message for the chaincode in JSON format (default "{}") -E, --escc string The name of the endorsement system chaincode to be used for this chaincode -h, --help help for instantiate -l, --lang string Language the chaincode is written in (default "golang") -n, --name string Name of the chaincode --peerAddresses stringArray The addresses of the peers to connect to -P, --policy string The endorsement policy associated to this chaincode --tlsRootCertFiles stringArray If TLS is enabled, the paths to the TLS root cert files of the peers to connect to. The order and number of certs specified should match the --peerAddresses flag -v, --version string Version of the chaincode specified in install/instantiate/upgrade commands -V, --vscc string The name of the verification system chaincode to be used for this chaincode ``` 全局標志： ``` --cafile string Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint --certfile string Path to file containing PEM-encoded X509 public key to use for mutual TLS communication with the orderer endpoint --clientauth Use mutual TLS when communicating with the orderer endpoint --connTimeout duration Timeout for client to connect (default 3s) --keyfile string Path to file containing PEM-encoded private key to use for mutual TLS communication with the orderer endpoint -o, --orderer string Ordering service endpoint --ordererTLSHostnameOverride string The hostname override to use when validating the TLS connection to the orderer. --tls Use TLS when communicating with the orderer endpoint --transient string Transient map of arguments in JSON encoding ``` ## 示例代碼 在下面的示例中，使用`peer chaincode instantiate`命令將名為`mycss`、 版本為1.0的鏈碼在`mychannel`通道上實例化，在啟用TLS加密通信的網絡中， 還需要使用全局標志--tls和--cafile來實例化鏈碼。 ``` ~$ export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem ~$ peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')" 2018-02-22 16:33:53.324 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc 2018-02-22 16:33:53.324 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc 2018-02-22 16:34:08.698 UTC [main] main -> INFO 003 Exiting..... ``` 在下面的示例中，沒有使用全局標志來實例化鏈碼，因為在禁用TLS的網絡中不需要--tls和--cafile全局標志： ``` ~$ peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')" ``` 2018-02-22 16:34:09.324 UTC \[chaincodeCmd\] checkChaincodeCmdParams -> INFO 001 Using default escc 2018-02-22 16:34:09.324 UTC \[chaincodeCmd\] checkChaincodeCmdParams -> INFO 002 Using default vscc 2018-02-22 16:34:24.698 UTC \[main\] main -> INFO 003 Exiting.....
