I have deployed a one org hyperledger fabric network over docker swarm. Where one node has an orderer, peer , ca and couchdb and other node has one couchdb and node. I was able to invoke basic chaincode over it. Now I want to deploy composer over it. But I am not sure what shall I give in request and event url of connection.json. I already tried giving individual IPs instead of localhost,but no luck. I used this tutorial to deploy one org fabric network over docker swarm.
