From fabric document create-join-channel, when I execute the command

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

it return error snippet following message:

Please make sure that channel name is new one and that there is no existing channel already with that name in the network.

for example, if you already created a channel with CHANNEL_NAME=mychannel, change the variable before you create another channel, by running something like export CHANNEL_NAME=mychannelanother

Got unexpected status: BAD_REQUEST

Unfortunately, this error message can mean many things. FYI, in the upcoming fabric v1.1 release, this message has been enhanced to include additional text.

Most commonly, for channel creation, this status indicates that the submitter does not have channel creation rights (which usually equates to admin authority for an org). However, as mac indicates, if the channel already exists you might also get this error.

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

This command strikes me as the likely culprit. This command should usually be paired with lines like:

export CORE_PEER_MSPCONFIGPATH=`pwd`/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp 
export CORE_PEER_LOCALMSPID=PeerOrg1

Which tell the peer command that the channel creation request should be signed using a particular admin's certificate. The default paths for the peer command's certificate material usually result in a standard user cert being used to sign.

回答3:

The reason you're getting this is probably because the docker-compose-cli.yaml file is still running the script.sh script. Comment out the line that invokes the script and it will run fine. Example:

# Comment out the line like the example below by adding a #
# command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME} ${DELAY} ${LANG}; sleep $TIMEOUT'```

I am suggesting a documentation change to fix this.

回答4:

I had similar error. There seems to be a issue with the way CHANNEL_NAME variable is set within the docker-compose (I guess?). I ran this command with a slight modification as below [changed flag '-c $CHANNEL_NAME' to '-c mychannel']:

peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

This worked.

回答5:

As @Phil said, you should comment out that line before you start the network. As documentation says :

If left uncommented, that script will exercise all of the CLI commands when the network is started, as we describe in the What’s happening behind the scenes? section. However, we want to go through the commands manually in order to expose the syntax and functionality of each call.

see the doc

The same thing happens to me but I just down the network and then done all procedure again like generate genesis block again and then up my network I got up a network.
