问题
I'm running the fabcar example from fabric samples on a node. My fabric network is first-network (BYFN) run inside docker containers and I would like to invoke chaincode using a node.js fabric-client application on a separate node (Raspberry Pi).
In connection-org1.json file, I have replaced the localhost domain names (in the peer urls) with my own domain name (mydomain.com) where the fabric network is running.
I execute invoke.js on Raspberry Pi with the following modified gateway settings:
await gateway.connect(ccpPath, { wallet, identity: 'user1', discovery: { enabled: true, asLocalhost: false } });
This gives me an error message:
2019-07-04T07:15:30.124Z - error: [Remote.js]: Error: Failed to connect before the deadline URL:grpcs://peer0.org1.example.com:7051
2019-07-04T07:15:30.132Z - warn: [DiscoveryEndorsementHandler]: _build_endorse_group_member >> G0:0 - endorsement failed - Error: Failed to connect before the deadline URL:grpcs://peer0.org1.example.com:7051
2019-07-04T07:15:30.134Z - error: [Remote.js]: Error: Failed to connect before the deadline URL:grpcs://peer0.org2.example.com:9051

Failed to submit transaction: Error: Endorsement has failed
I see that the domain names of the endorserers are the ones defined in the docker composer files, not the domain (mydomain.com) where my fabric network is running.
How should I configure the fabric network or the node.js fabric-client application so that I can invoke chaincode from my Raspberry Pi node?
回答1:
I made a workaround where I extended the /etc/hosts file on my Raspberry Pi. I made the endorsing peer domain names peer0.org1.example.com and peer0.org2.example.com to point to the IP address of my host where I run the fabric network (docker).
This fixed the issue and now I'm able to invoke chaincode from the Raspberry Pi host.
