Cannot create a channel in Hyperledger fabric docker setup?

Question

Problem:

I am very new to Hyperledger fabric stuff. I tried to build a network from scratch with docker. Everything work fine and network was up successfully. But when I was trying to create a channel it gave me this error.

I looked for solutions on the Internet but I was unable to find a good solution for my problem. Can someone help me to solve my problem?. Thank you!

Answer 1

@dwp, As per your volume mounts your source directory in your machine ("./crypto-config") was mounted to your container ("/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/")...

And the error says (let's take first one) ==> Intermediate certs folder not found at /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/Policedepartment.trafficfine.com/users/Admin@Policedepartment.trafficfine.com/msp/intermediatecerts

means there is no directory "./crypto-config/peerOrganizations/Policedepartment.trafficfine.com/users/Admin@Policedepartment.trafficfine.com/msp/intermediatecerts"..

So try to change the volume mount source and targets according to your crypto-config files..

To debug more into cli container use,

docker exec -it cli bash

Answer 2

Did you generate the new crypto material? Try this:

docker container exec -it cli bash

And search for the crypto directory, the error says that not found your crypto material files in your container, and you need it to make transactions over the network.
