A

If you are the MagnetoCorp administrator, you need to use the peer chaincode install command to copy the papercontract chaincode from their local machine’s file system to the file system within the target peer’s docker container. Once the chaincode is installed on the peer and instantiated on a channel, papercontract can be invoked by client applications.

1. Install the chaincode:

(magnetocorp admin)$ cd ~/hyperledger-binaries/fabric-samples
(magnetocorp admin)$ cd commercial-paper/organization/magnetocorp/contract
(magnetocorp admin)$ docker exec cliMagnetoCorp peer chaincode install -n papercontract \
   -v 0 -p /opt/gopath/src/github.com/contract -l node

[chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
[chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
[chaincodeCmd] install -> INFO 003 Installed remotely response:<status:200 payload:"OK" >

Note that the "peer chaincode install" command takes the chaincode from the path on the cliMagnetoCorp container, /opt/gopath/src/github.com/contract, which is mapped to the commercial-paper/organization/magnetocorp/contract on the local system in the docker-compose.yml file.

2. Verify the installed chaincode:

(magnetocorp admin)$ docker exec cliMagnetoCorp peer chaincode list --installed
Get installed chaincodes on peer:
Name: papercontract, Version: 0, Path: /opt/gopath/src/github.com/contract,
