问题
I am trying to pass in the channel configuration transaction artifact to the order-er using the command:
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -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
But I get an error:
2018-03-17 20:55:21.380 GMT [main] main -> ERRO 001 Fatal error
when initializing core config : error when reading core
config file: Unsupported Config Type ""
What does this error mean? and how can I fix it?
Using docker ps -a

回答1:
You should be inside the CLI container to execute the peer channel create command.
You will enter the CLI container using the docker exec command:
docker exec -it cli bash
If successful you should see the following:
root@0d78bb69300d:/opt/gopath/src/github.com/hyperledger/fabric/peer#
Over there, you should run the peer channel create command like this:
root@0d78bb69300d:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
Before running this command, please note that you should also run commands for creating environment variables for CHANNEL_NAME and other Environment variables for PEER0 within this CLI Container.
回答2:
export FABRIC_CFG_PATH=$PWD. it will resolve this issue.
回答3:
Can you try running this command: echo $FABRIC_CFG_PATH
Whatever value you get, can you navigate to that directory and confirm if you can see the configtx.yaml file in there.
From the docs here, it says the error is as a result of inappropriately setting the value of that variable.
回答4:
This is the error you get when the core.yaml is not found. Like the Mukesh mentioned above, running command within the CLI Container will not throw the Error.
See this link for more detail.
