hyperledger fabric chaincode dev mode connection error

Question

I was following this tutorial of building a simple chaincode in dev mode here . I'm stuck here First I cleared everything with docker rm -f $(docker ps -aq) . When I enter docker-compose -f docker-compose-simple.yaml up it ends with this Error: Error getting broadcast client: Error connecting to orderer:7050 due to context deadline exceeded cli | Usage: cli | peer channel create [flags] cli | orderer | 2017-12-05 20:44:53.681 UTC [orderer/common/deliver] Handle -> WARN 0d1 Error reading from stream: rpc error: code = Canceled desc = context canceled orderer | 2017-12-05 20:44:53.681 UTC [orderer/main] func1 -> DEBU 0d2 Closing Deliver stream cli exited with code 1 Error: Error getting broadcast client: Error connecting to orderer:7050 due to context deadline exceeded cli | Usage: cli | peer channel create [flags] cli | orderer | 2017-12-05 20:44:53.681 UTC [orderer/common/deliver] Handle -> WARN 0d1 Error reading from stream: rpc error: code = Canceled desc = context canceled orderer | 2017-12-05 20:44:53.681 UTC [orderer/main] func1 -> DEBU 0d2 Closing Deliver stream cli exited with code 1 Error: Error getting broadcast client: Error connecting to orderer:7050 due to context deadline exceeded cli | Usage: cli | peer channel create [flags] cli | orderer | 2017-12-05 20:44:53.681 UTC [orderer/common/deliver] Handle -> WARN 0d1 Error reading from stream: rpc error: code = Canceled desc = context canceled orderer | 2017-12-05 20:44:53.681 UTC [orderer/main] func1 -> DEBU 0d2 Closing Deliver stream cli exited with code 1 What is causing problem? Is it dns problem that it can't find orderer?

Answer 1

Alright, I finally figured that out, the problem is in network, so I had in my virtual machine parameters set NAT for network, and nothing worked. I've set it to bridge mode and everything worked fine.
