Multiple peer nodes but only one dev-peer

Question

I have a Fabric Composer network with 3 peers in one organization.

The problem is that when I do docker stats I see only one 'Chain code container' dev-peer0.org1 and as far as I know there should be dev-peer for each peer node (Extra dev peers in hyperledger fabric)

Here is my connection profile

{
    "name": "hlfv1",
    "x-type": "hlfv1",
    "x-commitTimeout": 300,

        }
    }
}

Anybody knows what is wrong?

Answer 1

Got it. The problem was that I hadn't changed the startFabric.sh script so I had 3 peer nodes running but they didn't join the channel

Here is how startFabric.sh should look like:

...

# Create the channel and join for peer 0
docker exec peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c composerchannel -f /etc/hyperledger/configtx/composer-channel.tx
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer0.org1.example.com peer channel join -b composerchannel.block

# Create the channel and join for peer 1
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer1.org1.example.com peer channel fetch config -o orderer.example.com:7050 -c composerchannel
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer1.org1.example.com peer channel join -b composerchannel_config.block

# Create the channel and join for peer 2
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer2.org1.example.com peer channel fetch config -o orderer.example.com:7050 -c composerchannel
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer2.org1.example.com peer channel join -b composerchannel_config.block

if [ "${FABRIC_DEV_MODE}" == "true" ]; then
    echo "Fabric Network started in chaincode development mode"
fi
