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
  • 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 of myccv1 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 on peer0.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 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 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 the init-required flag to request the execution of the Init function to initialize the chaincode.

    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 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 named mycc at sequence number 1 on channel mychannel.

    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

  • You can also use the --output flag to have the CLI format the output as JSON.

    • When querying an approved chaincode definition for which package is specified

      peer lifecycle chaincode queryapproved -C mychannel -n mycc --sequence 1 --output json

      If successful, the command will return a JSON that has the approved chaincode definition for chaincode mycc at sequence number 1 on channel mychannel.

      {
  "sequence": 1,
  "version": "1",

      }
    }
  }
}

    • When querying an approved chaincode definition for which package is NOT specified

      peer lifecycle chaincode queryapproved -C mychannel -n mycc --sequence 2 --output json

      If successful, the command will return a JSON that has the approved chaincode definition for chaincode mycc at sequence number 2 on channel mychannel.

      {

    }
  }
}

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 Application/Channel/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 named mycc at version 1.0 on channel mychannel.

    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
