How to create a custom test-network in Hyperledger Fabric 2.x? How to create five peer org in a private channel in test-netork?

Question

For example, I want to create a private channel of five peer org. How should I configure my test-network? I've created org3 peerOrganizations using configtx.yaml but it doesn't get a container ID.

reference https://hyperledger-fabric.readthedocs.io/en/release-1.4/build_network.html

You need to perform these steps manually,because the script is not applicable.

this tutorials was base fabric v1.4.2,but I think it also applies to v2.x.

and I have put to git reposistory https://github.com/iamlzw/five-network.git

you need to clone this reposistory to $GOPATH/src/github.com/hyperledger/fabric-samples/

1、Configure configtx.yaml

you need configure Organizations: ,TwoOrgsOrdererGenesis and TwoOrgsChannel part of Profiles:，how many organizations you want join in network,then you need to configure how many organizations

reference https://github.com/iamlzw/byfn-with-five-org/blob/master/configtx.yaml

2、Configure crypto-config.yaml

you need configure PeerOrgs:,same as above,how many organizations you want join in network,then you need to configure how many organizations.

referene https://github.com/iamlzw/byfn-with-five-org/blob/master/crypto-config.yaml

3、Manually generate the artifacts generate crypto artifacts

../bin/cryptogen generate --config=./crypto-config.yaml

generate orderer genesis block

export FABRIC_CFG_PATH=$PWD
../bin/configtxgen -profile TwoOrgsOrdererGenesis -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block

4、Create a Channel Configuration Transaction

export CHANNEL_NAME=mychannel  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

5、Start the network

docker-compose -f docker-compose-e2e.yaml up -d

5.1 create and join channel

execute this command in your terminal not in cli container, because I dont start a cli container

so you need configure your /etc/hosts

sudo /etc/hosts

### change 192.168.126.128 to your IP or localhost or 127.0.0.1
192.168.126.128 orderer.example.com
192.168.126.128 peer0.org1.example.com 
192.168.126.128 peer1.org1.example.com
192.168.126.128 peer0.org2.example.com
192.168.126.128 peer1.org2.example.com
192.168.126.128 peer0.org3.example.com 
192.168.126.128 peer1.org3.example.com
192.168.126.128 peer0.org4.example.com
192.168.126.128 peer1.org4.example.com
192.168.126.128 peer0.org5.example.com
192.168.126.128 peer1.org5.example.com

next all steps you can execute script byfn_five.sh

5.1.1 create genesis block

5.1.3 instantiate chaincode,you need just instantiate chaincode on peer0.org1

#export peer0.org1 env
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=$GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

export CORE_PEER_ADDRESS=peer0.org1.example.com:7051

#instantiate chaincode on peer0.org1
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile $GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"

6、invoke and query

#export peer0.org1 env
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=$GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=$GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=peer0.org1.example.com:7051

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

# export peer0.org5 env
export CORE_PEER_LOCALMSPID="Org5MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=$GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org5.example.com/peers/peer0.org5.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=$GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org5.example.com/users/Admin@org5.example.com/msp
export CORE_PEER_ADDRESS=peer0.org5.example.com:15051

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

### invoke use peer0.org5
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile $GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles $GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles $GOPATH/src/github.com/hyperledger/fabric-samples/five-network/crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","2"]}'

### query
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
