Do docker-machine ls

Output:

$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOC default virtualbox Running tcp://192.168.99.100:2376 v17

  • copy the ip address mentioned , like : 192.168.99.100
  • go to \fabric-samples\fabcar\query.js
  • replace the localhost with the IP address

I have seen that error occur when datasources.json specifies that the network addresses start with grpcs://, but the network is not set up to use TLS. Try changing them to start with grpc://.

Addition to Angela's answer:

To anyone having this issue and using Docker Toolbox, do docker-machine ls and copy the IP adress at the URL column of your ACTIVE machine and paste the IP adress to every localhost in both query.js and invoke.js files.

I have met the same error during run sample, it failed to connect. I fixed it with following steps:

  1. get machine IP address with: ifconfig
  2. replace localhosts in query.js with IP in #1

Example:

@@ -12,7 +12,7 @@ var options = {
     user_id: 'PeerAdmin',
     channel_id: 'mychannel',
     chaincode_id: 'fabcar',
-    network_url: 'grpc://localhost:7051',
+    network_url: 'grpc://****:7051',
};
