You can find the orderer.yaml file at fabric-samples/config folder. Going through the fields and their respective comments in orderer.yaml and core.yaml can help you to understand the method of configuring the network(orderer/peer).

And here you can get the info related to TLS.

  • Thanks for your reply.But i have already given the tls enabled and required keys and certificates in peers and orderer in docker files.Do i need to modify the core.yaml and orderer.yaml as i didnt find any link that firstnetwork in fabric samples is using config folder's files @rohit_sethi – Sahithi Dyavarasahetti Mar 12 '19 at 11:48
  • As mentioned in link send by you, i have added tls enabled certificates and keys in peers and orderer containers – Sahithi Dyavarasahetti Mar 12 '19 at 11:50

    I am working on multi organisation network setup using first network of fabric samples.one of the organisation say org1 has created a channel by passing tls certs of orderer ,the other organisation org2 has to fetch the channel created by org1 and join the peers into the channel.when i do fetch action using peer channel fetch by passing tls certs of orderer ,i got the error like ""connection error: desc = "transport: Error while dialing dial tcp 98.124.199.121:7050: connect: connection refused". Reconnecting..."". – Sahithi Dyavarasahetti Mar 12 '19 at 12:40
  • and in orderer logs ,i got error as :TLS handshake failed with error tls: client didn't provide a certificate {"server": "Orderer", "remote address": "172.24.0.4:49608"} – Sahithi Dyavarasahetti Mar 12 '19 at 12:42
  • `CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt` - `CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key` - `CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt` set these environment variables and then try again – rohit_sethi Mar 12 '19 at 13:19
