How to switch the default peer on BYFN CLI Container? I want to join peer0.org2.example.com to the channel.

You can follow this tutorial to switch the default peer to peer0.org2.example.com and join it to BYFN "mychannel" channel.

1. Switch the default peer by channing envrionment variables:

bash-4.4# export CORE_PEER_ADDRESS=peer0.org2.example.com:7051

bash-4.4# export CORE_PEER_LOCALMSPID=Org2MSP

bash-4.4# export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger\
   /fabric/peer/crypto/peerOrganizations/org2.example.com/users\
   /Admin@org2.example.com/msp

bash-4.4# export 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

2. Check default peer, peer0.org2.example.com, status:

bash-4.4# peer node status
status:STARTED

bash-4.4# peer channel list
[channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
Channels peers has joined:

3. Join the default peer to channel "mychannel":

bash-4.4# peer channel join -b mychannel.block
[channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
[channelCmd] executeJoin -> INFO 002 Successfully submitted proposal to join channel

bash-4.4# peer channel list

[channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
Channels peers has joined:
mychannel

peer.org2.example.com has joined the "mychannel".
