BYFN CLI "peer" Command Prefix
How to use BYFN CLI "peer" Command Prefix?
✍: FYIcenter.com
By default, when you run the "peer" command on the BYFN CLI container,
it will be executed again the default peer node
specified by 4 environment variables:
CORE_PEER_MSPCONFIGPATH=/opt/gopath/.../org1.example.com/users/Admin@org1.example.com/msp CORE_PEER_ADDRESS=peer0.org1.example.com:7051 CORE_PEER_LOCALMSPID=Org1MSP CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/.../org2.example.com/peers/peer0.org1.example.com/tls/ca.crt
If you want to switch to different peer node, you have to re-define those 4 variables, which takes 4 commands to do.
Another quick solution is to prefix the "peer" command to override those variables. For example, the following command list installed chaincodes on peer0.org2 peer node, not the default peer node.
1. Connect to the BYFN CLI container and check the default peer:
$ docker exec -it cli bash bash-4.4# echo $CORE_PEER_ADDRESS peer0.org2.example.com:7051
2. Run "peer" command on default peer, peer0.org1:
bash-4.4# peer node status status:STARTED
1. Run "peer" command on peer0.org2:
bash-4.4# CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger\ /fabric/peer/crypto/peerOrganizations/org2.example.com/users\ /Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer0.org2.example.com:7051 \ CORE_PEER_LOCALMSPID=Org2MSP CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src\ /github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com\ /peers/peer0.org2.example.com/tls/ca.crt \ peer node status status:STARTED
2. Run "peer" command on pee0.org2:
bash-4.4# CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger\ /fabric/peer/crypto/peerOrganizations/org2.example.com/users\ /Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer0.org2.example.com:7051 \ CORE_PEER_LOCALMSPID=Org2MSP CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src\ /github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com\ /peers/peer0.org2.example.com/tls/ca.crt \ peer node status status:STARTED
