How to run "configtxgen" command to build a transaction message to create the channel in BYFN (Build Your First Network)?

You can follow this tutorial to run "configtxgen" command to build a transaction message to create the channel in BYFN.

The "configtxgen" command file is located in the ../bin directory. It takes the configtx.yaml file as the input with the help of FABRIC_CFG_PATH environment variable:

$ cd hyperledger-binaries/fabric-samples/first-network

$ export FABRIC_CFG_PATH=./
$ mkdir ./channel-artifacts
$ ../bin/configtxgen -profile TwoOrgsChannel -channelID mychannel \
   -outputCreateChannelTx ./channel-artifacts/channel.tx 

...[common.tools.configtxgen] main -> INFO 001 Loading configuration
...[common.tools.configtxgen.localconfig] Load -> INFO 002 Loaded configuration: \ 
   /home/fyicenter/hyperledger-binaries/fabric-samples/first-network/configtx.yaml
...[common.tools.configtxgen.localconfig] completeInitialization \
   -> INFO 003 orderer type: solo
...[common.tools.configtxgen.localconfig] LoadTopLevel -> INFO 004 Loaded configuration: \
   /home/fyicenter/hyperledger-binaries/fabric-samples/first-network/configtx.yaml
...[common.tools.configtxgen] doOutputChannelCreateTx -> INFO 005 Generating new channel configtx
...[common.tools.configtxgen] doOutputChannelCreateTx -> INFO 006 Writing new channel tx

The transaction message is generated in the ./channel-artifacts sub-directory and named as "channel.tx":

$ ls -l ./channel-artifacts

-rw-r--r-- 1 fyicenter 12988 Apr  1 01:26 channel.tx

⇒ "configtxgen" Command - Build *MSPanchors.tx
