Create & Join Channel in Hyperledger Fabric Build your First Network Walk Through

I am trying create a channel according to documentation

Hyperledger Fabric v1.0 docs Have an issue with certificate. On the docker "hyperledger/fabric-tools" node I can find certificate with current name - tlsca.example.com. But the channel cannot be created. I have certificate hand shake issue. Should I check/mount certificate to the peer node ? 

root@4b6423da537b:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com# 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

i meet the same problem. And run this command to close the network. 

./network_setup.sh down mychannel

The reason that cause my problem is that the source code exists a error. So i modify this code error and reopen the network. This problem work out.

It would seem that you are in the incorrect working directory. When running the sample manually, you start the cli container and it places you in the /opt/gopath/src/github.com/hyperledger/fabric/peer directory. That is where you should be running the peer command. It would seem from your post that you were running the peer command in the /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com directory in the container, and it is not finding the configuration files that were mounted for the example.
