使用 Fabric Node SDK 向现有 Hyperledger Fabric 网络添加新组织

Question

Here is where I am at the moment:

Fabric version 1.4.1 Using byfn.sh to create Org1, Org2, Orderer etc and bring the channel mychannel up Language: Node using Typescript

I have followed the instructions in this tutorial to add a third org Org3 https://medium.com/@kctheservant/add-a-new-organization-on-existing-hyperledger-fabric-network-2c9e303955b2

This works great.

Now, I would like to add another Org but using the Fabric Node SDK. Is that possible?

Scenario is this:

1. A network admin logs into a custom UI being developed to manage a Fabric network.
2. The admin inputs details such as new Org name, MSP ID, peers info into the UI

3. The UI invokes a service layer which will

   1. Invoke a Fabric Node SDK API to create crypto materials for the new Org b.
   2. Invoke Fabric Node SDK API to create the new Org and have it join the channel mychannel
   3. Install chaincode to the new Org's peers d.
   4. Run some tests of invoke and query chaincode to ensure that the new Org can query and submit transactions

In the last step, I will save the new channel configuration and the new Org configuration to yaml or json files.

I have looked at the Node SDK and have seen the Organization and Channel methods. However, it seems like the Organization class is not exposed as a type for Typescript, so I am not sure how to use it.

It would help if someone could explain the methods I need to use to get to what I am trying to do.

I would appreciate any help.

Thanks in advance.

Answer 1

Actually, the title of the article is misleading. In the article, you are adding a new org in the existing channel not in the network.

Please take a look at the official documentation. The same tutorial.
Adding an Org to a Channel

For your requirement, yes we can do the same using the node sdk.

Check out this tutorial. update channel config

In the tutorial, they are updating the channel id to create a new channel with that id.

You can use the same steps to update the organizations.

You have to run shell command using either by shell.js or child-process .

Hope it will clear your doubts.
