Something wrong on deploy chaincode for hyperledger v1.0

Question

I have tried to use docker toolbox to setup Hyperledger V1.0 in my local machines. I according to this document： http://hyperledger-fabric.readthedocs.io/en/latest/asset_setup.html

But when I tried to deploy chaincode.

$node deploy.js

I got an error message：

Is this an question about unable to connect to ca? Or other causes?

Edit:

Environment:

OS: Windows 10 Professional Edition
Docker Toolbox: 17.04.0-ce
Go: 1.7.5
Node.js: 6.10.0

My steps:

1.Open Docker Quickstart Terminal and key commands.

$curl -L https://raw.githubusercontent.com/hyperledger/fabric/master/examples/sfhackfest/sfhackfest.tar.gz -o sfhackfest.tar.gz 2> /dev/null;  tar -xvf sfhackfest.tar.gz

$docker-compose -f docker-compose-gettingstarted.yml build

$docker-compose -f docker-compose-gettingstarted.yml up -d

$docker ps

It has been confirmed that six containers have been activated

2.Download examples and install modules.

$curl -OOOOOO https://raw.githubusercontent.com/hyperledger/fabric-sdk-node/v1.0-alpha/examples/balance-transfer/{config.json,deploy.js,helper.js,invoke.js,query.js,package.json}
//This link didn't work, so I downloaded the required files from GitHub of fabric-sdk-node

$npm install --global windows-build-tools

$npm install

3.Try to deploy chaincode.

$node deploy.js

Answer 1

There were several problems, not the least of which that documentation was outdated and was for a preview release of Hyperledger Fabric. The docs are actually in the process of being removed as we need to update our examples / samples.

You mentioned Docker Toolbox - so are you trying to run all of this on Windows or Mac?

UPDATE:

So one of the issue with Docker Toolbox or Docker for Windows is that you cannot use localhost / 127.0.0.1 as the address when trying to communicate from apps on the host (even in the QuickStart Terminal) to the endpoints of the Docker containers. When the QuickStart Terminal first launches Docker, you'll see that it will output the IP address of the endpoint you should use when communicating with exposed ports.

Answer 2

I was having the same issue while following the latest "Writing Your First Application" tutorial (http://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html). I had installed all the pre-requisites and the fabric-samples and started the local network.

When I got to the step of enrolling the Admin user, $ node enrollAdmin.js, I was getting the same error message as above, Error: connect ECONNREFUSED, followed by the localhost domain.

As the first answer suggests, the root cause is that I'm running Docker Toolbox. I'm developing on an older Mac, OSX v10.9.5, so I couldn't use Docker for Mac.

To fix the issue, I replaced 'localhost' in the enrollAdmin.js code with the IP from Docker Toolbox.

Here are the steps I took:

1. Started Docker with Applications > Docker Quickstart Terminal
2. Copied the IP from this sentence: docker is configured to use the default machine with IP...
3. Opened the copy of enrollAdmin.js from fabric-samples/fabcar directory

4. Found this code:

   // be sure to change the http to https when the CA is running TLS enabled
   fabric_ca_client = new Fabric_CA_Client('http://localhost:7054', tlsOptions , 'ca.example.com', crypto_suite); // <-- This is the line to change
   

5. Replaced 'localhost' with the Docker IP, leaving the port :7054 as is.
6. Saved
7. Re-ran the command, $ node enrollAdmin.js

The script connected to the CA and successfully completed the Admin enrollment.

On to the next step!
