How to run "configtxgen" command to build a transaction message to define the anchor peer in each organization in BYFN (Build Your First Network)?

You can follow this tutorial to run "configtxgen" command to build a transaction message to define the anchor peer in each organization 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 -asOrg Org1MSP \
   -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx 

...
...[common.tools.configtxgen] doOutputAnchorPeersUpdate -> INFO 005 Generating anchor peer update
...[common.tools.configtxgen] doOutputAnchorPeersUpdate -> INFO 006 Writing anchor peer update

$ ../bin/configtxgen -profile TwoOrgsChannel -channelID mychannel -asOrg Org2MSP \
   -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx 

...
...[common.tools.configtxgen] doOutputAnchorPeersUpdate -> INFO 005 Generating anchor peer update
...[common.tools.configtxgen] doOutputAnchorPeersUpdate -> INFO 006 Writing anchor peer update

Transaction messages for both organizations are generated in the ./channel-artifacts sub-directory and named as "Org1MSPanchors.tx" and "Org2MSPanchors":

$ ls -l ./channel-artifacts

-rw-r--r-- 1 fyicenter 12988 Apr  1 01:26 Org1MSPanchors.tx
-rw-r--r-- 1 fyicenter 12988 Apr  1 01:26 Org2MSPanchors.tx
