peer chaincode upgrade
升级指定的链码。当交易提交后新的链码将立即替代原来的链码。
使用方法
~$ peer chaincode upgrade [flags]
命令标志
-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 upgrade
-l, --lang string Language of chaincode, either "golang" (default), "node", or "java"
-n, --name string Name of the chaincode
-p, --path string Path to chaincode, for "golang" use relative path from $GOPATH/src, for "node" or "java" use absolute path
--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
全局标志：
--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
示例代码
下面的示例使用peer chaincode upgrade命令将版本1.0的mycc链码升级为版本1.1，该新版本链码
包含了一个新的变量c。在启用TLS的网络中使用全局标志--tls和--cafile：
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 upgrade -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C mychannel -n mycc -v 1.2 -c '{"Args":["init","a","100","b","200","c","300"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"
