peer lifecycle chaincode¶
The peer lifecycle chaincode
subcommand allows administrators to use the
Fabric chaincode lifecycle to package a chaincode, install it on your peers,
approve a chaincode definition for your organization, and then commit the
definition to a channel. The chaincode is ready to be used after the definition
has been successfully committed to the channel. For more information, visit
Fabric chaincode lifecycle.
Note: These instructions use the Fabric chaincode lifecycle introduced in the v2.0 release. If you would like to use the old lifecycle to install and instantiate a chaincode, visit the peer chaincode command reference.
Syntax¶
The peer lifecycle chaincode
command has the following subcommands:
package
install
queryinstalled
getinstalledpackage
calculatepackageid
approveformyorg
queryapproved
checkcommitreadiness
commit
querycommitted
Each peer lifecycle chaincode subcommand is described together with its options in its own section in this topic.

Example Usage¶
peer lifecycle chaincode package example¶
A chaincode needs to be packaged before it can be installed on your peers.
This example uses the peer lifecycle chaincode package
command to package
a Go chaincode.
Use the
--path
flag to indicate the location of the chaincode. The path must be a fully qualified path or a path relative to your present working directory.Use the
--label
flag to provide a chaincode package label ofmyccv1
that your organization will use to identify the package.peer lifecycle chaincode package mycc.tar.gz --path $CHAINCODE_DIR --lang golang --label myccv1
peer lifecycle chaincode install example¶
After the chaincode is packaged, you can use the peer chaincode install
command
to install the chaincode on your peers.
Install the
mycc.tar.gz
package onpeer0.org1.example.com:7051
(the peer defined by--peerAddresses
).peer lifecycle chaincode install mycc.tar.gz --peerAddresses peer0.org1.example.com:7051
If successful, the command will return the package identifier. The package ID is the package label combined with a hash of the chaincode package taken by the peer.

peer lifecycle chaincode queryinstalled example¶
You need to use the chaincode package identifier to approve a chaincode
definition for your organization. You can find the package ID for the
chaincodes you have installed by using the
peer lifecycle chaincode queryinstalled
command:
peer lifecycle chaincode queryinstalled --peerAddresses peer0.org1.example.com:7051
A successful command will return the package ID associated with the package label.
Get installed chaincodes on peer:
Package ID: myccv1:a7ca45a7cc85f1d89c905b775920361ed089a364e12a9b6d55ba75c965ddd6a9, Label: myccv1
You can also use the
--output
flag to have the CLI format the output as JSON.peer lifecycle chaincode queryinstalled --peerAddresses peer0.org1.example.com:7051 --output json
If successful, the command will return the chaincodes you have installed as JSON.
{ "installed_chaincodes": [ { "package_id": "mycc_1:aab9981fa5649cfe25369fce7bb5086a69672a631e4f95c4af1b5198fe9f845b", "label": "mycc_1", "references": { "mychannel": { "chaincodes": [ { "name": "mycc", "version": "1" } ] } } } ] }
peer lifecycle chaincode getinstalledpackage example¶
You can retrieve an installed chaincode package from a peer using the
peer lifecycle chaincode getinstalledpackage
command. Use the package
identifier returned by queryinstalled
.
Use the
--package-id
flag to pass in the chaincode package identifier. Use the--output-directory
flag to specify where to write the chaincode package. If the output directory is not specified, the chaincode package will be written in the current directory.
peer lifecycle chaincode getinstalledpackage --package-id myccv1:a7ca45a7cc85f1d89c905b775920361ed089a364e12a9b6d55ba75c965ddd6a9 --output-directory /tmp --peerAddresses peer0.org1.example.com:7051
peer lifecycle chaincode calculatepackageid example¶
You can calculate the package ID from a packaged chaincode without installing the chaincode on peers
using the peer lifecycle chaincode calculatepackageid
command.
This command will be useful, for example, in the following cases:
When multiple chaincode packages with the same label name are installed, it is possible to identify which ID corresponds to which package later.
To check whether a particular chaincode package is installed or not without installing that package.
Calculate the package ID for the mycc.tar.gz
package:
peer lifecycle chaincode calculatepackageid mycc.tar.gz
A successful command will return the package ID for the packaged chaincode.
myccv1:cc7bb5f50a53c207f68d37e9423c32f968083282e5ffac00d41ffc5768dc1873
You can also use the
--output
flag to have the CLI format the output as JSON.peer lifecycle chaincode calculatepackageid mycc.tar.gz --output json
If successful, the command will return the chaincode package ID as JSON.
{ "package_id": "myccv1:cc7bb5f50a53c207f68d37e9423c32f968083282e5ffac00d41ffc5768dc1873" }
peer lifecycle chaincode approveformyorg example¶
Once the chaincode package has been installed on your peers, you can approve a chaincode definition for your organization. The chaincode definition includes the important parameters of chaincode governance, including the chaincode name, version and the endorsement policy.
Here is an example of the peer lifecycle chaincode approveformyorg
command,
which approves the definition of a chaincode named mycc
at version 1.0
on
channel mychannel
.
Use the
--package-id
flag to pass in the chaincode package identifier. Use the--signature-policy
flag to define an endorsement policy for the chaincode. Use theinit-required
flag to require the execution of an initialization function before other chaincode functions can be called.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 lifecycle chaincode approveformyorg -o orderer.example.com:7050 --tls --cafile $ORDERER_CA --channelID mychannel --name mycc --version 1.0 --init-required --package-id myccv1:a7ca45a7cc85f1d89c905b775920361ed089a364e12a9b6d55ba75c965ddd6a9 --sequence 1 --signature-policy "AND ('Org1MSP.peer','Org2MSP.peer')" 2019-03-18 16:04:09.046 UTC [cli.lifecycle.chaincode] InitCmdFactory -> INFO 001 Retrieved channel (mychannel) orderer endpoint: orderer.example.com:7050 2019-03-18 16:04:11.253 UTC [chaincodeCmd] ClientWait -> INFO 002 txid [efba188ca77889cc1c328fc98e0bb12d3ad0abcda3f84da3714471c7c1e6c13c] committed with status (VALID) at peer0.org1.example.com:7051

peer lifecycle chaincode queryapproved example¶
You can query an organization’s approved chaincode definition by using the peer lifecycle chaincode queryapproved
command.
You can use this command to see the details (including package ID) of approved chaincode definitions.
Here is an example of the
peer lifecycle chaincode queryapproved
command, which queries the approved definition of a chaincode namedmycc
at sequence number1
on channelmychannel
.peer lifecycle chaincode queryapproved -C mychannel -n mycc --sequence 1 Approved chaincode definition for chaincode 'mycc' on channel 'mychannel': sequence: 1, version: 1, init-required: true, package-id: mycc_1:d02f72000e7c0f715840f51cb8d72d70bc1ba230552f8445dded0ec8b6e0b830, endorsement plugin: escc, validation plugin: vscc
If NO package is specified for the approved definition, this command will display an empty package ID.
You can also use this command without specifying the sequence number in order to query the latest approved definition (latest: the newer of the currently defined sequence number and the next sequence number).
peer lifecycle chaincode queryapproved -C mychannel -n mycc Approved chaincode definition for chaincode 'mycc' on channel 'mychannel': sequence: 3, version: 3, init-required: false, package-id: mycc_1:d02f72000e7c0f715840f51cb8d72d70bc1ba230552f8445dded0ec8b6e0b830, endorsement plugin: escc, validation plugin: vscc

peer lifecycle chaincode checkcommitreadiness example¶
You can check whether a chaincode definition is ready to be committed using the
peer lifecycle chaincode checkcommitreadiness
command, which will return
successfully if a subsequent commit of the definition is expected to succeed. It
also outputs which organizations have approved the chaincode definition. If an
organization has approved the chaincode definition specified in the command, the
command will return a value of true. You can use this command to learn whether enough
channel members have approved a chaincode definition to meet the
/Channel/Application/Endorsement
policy (a majority by default) before the
definition can be committed to a channel.
Here is an example of the
peer lifecycle chaincode checkcommitreadiness
command, which checks a chaincode namedmycc
at version1.0
on channelmychannel
.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 lifecycle chaincode checkcommitreadiness -o orderer.example.com:7050 --channelID mychannel --tls --cafile $ORDERER_CA --name mycc --version 1.0 --init-required --sequence 1
If successful, the command will return the organizations that have approved the chaincode definition.
Chaincode definition for chaincode 'mycc', version '1.0', sequence '1' on channel 'mychannel' approval status by org: Org1MSP: true Org2MSP: true
You can also use the
--output
flag to have the CLI format the output as JSON.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 lifecycle chaincode checkcommitreadiness -o orderer.example.com:7050 --channelID mychannel --tls --cafile $ORDERER_CA --name mycc --version 1.0 --init-required --sequence 1 --output json
If successful, the command will return a JSON map that shows if an organization has approved the chaincode definition.
{ "Approvals": { "Org1MSP": true, "Org2MSP": true } }
peer lifecycle chaincode commit example¶
Once a sufficient number of organizations approve a chaincode definition for
their organizations (a majority by default), one organization can commit the
definition the channel using the peer lifecycle chaincode commit
command:
This command needs to target the peers of other organizations on the channel to collect their organization endorsement for the definition.
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 lifecycle chaincode commit -o orderer.example.com:7050 --channelID mychannel --name mycc --version 1.0 --sequence 1 --init-required --tls --cafile $ORDERER_CA --peerAddresses peer0.org1.example.com:7051 --peerAddresses peer0.org2.example.com:9051 2019-03-18 16:14:27.258 UTC [chaincodeCmd] ClientWait -> INFO 001 txid [b6f657a14689b27d69a50f39590b3949906b5a426f9d7f0dcee557f775e17882] committed with status (VALID) at peer0.org2.example.com:9051 2019-03-18 16:14:27.321 UTC [chaincodeCmd] ClientWait -> INFO 002 txid [b6f657a14689b27d69a50f39590b3949906b5a426f9d7f0dcee557f775e17882] committed with status (VALID) at peer0.org1.example.com:7051
peer lifecycle chaincode querycommitted example¶
You can query the chaincode definitions that have been committed to a channel by
using the peer lifecycle chaincode querycommitted
command. You can use this
command to query the current definition sequence number before upgrading a
chaincode.
You need to supply the chaincode name and channel name in order to query a specific chaincode definition and the organizations that have approved it.
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 lifecycle chaincode querycommitted -o orderer.example.com:7050 --channelID mychannel --name mycc --tls --cafile $ORDERER_CA --peerAddresses peer0.org1.example.com:7051 Committed chaincode definition for chaincode 'mycc' on channel 'mychannel': Version: 1, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc Approvals: [Org1MSP: true, Org2MSP: true]
You can also specify just the channel name in order to query all chaincode definitions on that channel.
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 lifecycle chaincode querycommitted -o orderer.example.com:7050 --channelID mychannel --tls --cafile $ORDERER_CA --peerAddresses peer0.org1.example.com:7051 Committed chaincode definitions on channel 'mychannel': Name: mycc, Version: 1, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc Name: yourcc, Version: 2, Sequence: 3, Endorsement Plugin: escc, Validation Plugin: vscc
You can also use the
--output
flag to have the CLI format the output as JSON.For querying a specific chaincode definition
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 lifecycle chaincode querycommitted -o orderer.example.com:7050 --channelID mychannel --name mycc --tls --cafile $ORDERER_CA --peerAddresses peer0.org1.example.com:7051 --output json
If successful, the command will return a JSON that has committed chaincode definition for chaincode ‘mycc’ on channel ‘mychannel’.
{ "sequence": 1, "version": "1", "endorsement_plugin": "escc", "validation_plugin": "vscc", "validation_parameter": "EiAvQ2hhbm5lbC9BcHBsaWNhdGlvbi9FbmRvcnNlbWVudA==", "collections": {}, "init_required": true, "approvals": { "Org1MSP": true, "Org2MSP": true } }
The
validation_parameter
is base64 encoded. An example of the command to decode it is as follows.echo EiAvQ2hhbm5lbC9BcHBsaWNhdGlvbi9FbmRvcnNlbWVudA== | base64 -d /Channel/Application/Endorsement
For querying all chaincode definitions on that channel
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 lifecycle chaincode querycommitted -o orderer.example.com:7050 --channelID mychannel --tls --cafile $ORDERER_CA --peerAddresses peer0.org1.example.com:7051 --output json
If successful, the command will return a JSON that has committed chaincode definitions on channel ‘mychannel’.
