While creating a channel in Hyperledger fabric, which of the following Docker commands will you use for updating the anchor peer for the Org2 organization?

To update the anchor peer for the Org2 organization while creating a channel in Hyperledger Fabric, you would use the following Docker command:

docker exec -e "CORE_PEER_LOCALMSPID=Org2MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org2.example.com peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx

Here's a step-by-step breakdown of the command:

1. docker exec: This command is used to run a new command in a running container.

2. -e "CORE_PEER_LOCALMSPID=Org2MSP": This sets the environment variable CORE_PEER_LOCALMSPID to Org2MSP. This is used to specify the MSP ID of the peer's organization.

3. -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp": This sets the environment variable CORE_PEER_MSPCONFIGPATH to the path of the MSP configuration for the admin user of Org2.

4. peer0.org2.example.com: This is the name of the Docker container for the peer.

5. peer channel update: This is the command to update the channel.

6. -o orderer.example.com:7050: This specifies the orderer endpoint.

7. -c $CHANNEL_NAME: This specifies the name of the channel.

8. -f ./channel-artifacts/Org2MSPanchors.tx: This specifies the file that contains the configuration update for setting the anchor peer for Org2.
