# Fabric Full Stack Development Workshop
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
Hyperledger Fabric can be used to represent assets of any kind on a permissioned decentralized ledger, from fungible tokens to non-fungible tokens, including monetary products, marbles, pineapples, classic cars, fine art, and anything else you can imagine.
|
||||||
|
Fabric can be used to track and update anything about these assets, common examples include asset ownership, exchange, provenance, and lifecycle.
|
||||||
|
|
||||||
|
This workshop will demonstrate how a generic asset transfer solution can be modeled and deployed to take advantage of a blockchains qualitites of service.
|
||||||
|
|
||||||
|
The workshop will be split into three sections:
|
||||||
|
- Smart Contract Development
|
||||||
|
- Client Application Development
|
||||||
|
- Cloud Native Fabric Deployment
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
**OBJECTIVES:**
|
||||||
|
|
||||||
|
- Show how an Asset Transfer smart contract can be written to encapsulate business logic
|
||||||
|
- Show how the smart contract can be developed iteratively to get correct function in a development context
|
||||||
|
- Show how client applications can be written using the Gateway functionality
|
||||||
|
- Show how the simplification of the Gateway programming model makes connecting applications more streamlined
|
||||||
|
- Show how this streamlined approach improves resilience and availability
|
||||||
|
- Show how the solution can then be deployed to a production-class environment
|
||||||
|
- Show how a Hyperledger Fabric network can be created and managed in Kubernetes (K8S) using automation
|
||||||
|
- Show how the Fabric Operator and Console can be installed via Ansible playbooks
|
||||||
|
- Show how a multi-organization configuration of Fabric can be created
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
**Please ensure you've got the [required tools](./SETUP.md) on your local machine or in a virtual machine -- To check, run `./check.sh`**
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
|
||||||
|
## Before you begin....
|
||||||
|
|
||||||
|
Fabric is a multi-server decentralized system with orderer and peer nodes, so it can be quite complex to configure. Even the simplest smart contract needs a running Fabric Infrastructure and one size does not fit all.
|
||||||
|
|
||||||
|
There are configurations that can run Fabric either as local binaries, in a single docker container, in multiple containers, or in K8S.
|
||||||
|
This workshop will show some of the approaches that can be used for developing applications and contracts with a minimal Fabric environment (Microfab), and how a production deployment can be achieved.
|
||||||
|
There are other ways of deploying Fabric produced by the community - these are equally valid and useful. Feel free to try the others, once you understand the basic concepts to find what works best for you.
|
||||||
|
|
||||||
|
At a high-level remember that a solution using Fabric has (a) client application to send in transaction requests (b) Fabric infrastructure to service those requests (c) Smart Contract to action the transactions.
|
||||||
|
The nature of (b) the fabric infrastructure will change depending on your scenario; start simple and build up. The smart contracts and client application's code will remain the same no matter the way Fabric is provisioned.
|
||||||
|
There will be minor variations in deployment (eg local docker container vs remote K8S cluster) but fundamentally the process is the same.
|
||||||
|
|
||||||
|
## Running the workshop
|
||||||
|
|
||||||
|
 If you're running on Windows, please check the [hints and tips](./docs/tips-for-windows-dev.md)
|
||||||
|
|
||||||
|
- Ensure you've got the tools you may need, either installed locally or in a multipass virtual machine. See the [setup page](./SETUP.md) for details.
|
||||||
|
- Clone this repository to a convient location
|
||||||
|
- We suggest that you open 3 or 4 terminal windows
|
||||||
|
- One for running chaincode in dev mode
|
||||||
|
- One for running the fabric infrastructure and optionally one for monitoring it
|
||||||
|
- One for client applications
|
||||||
|
|
||||||
|
- Work through the sections below in order, although you don't necessarily need to complete all the Exercises before moving to the next section.
|
||||||
|
|
||||||

|
||||||
|
## Scenario
|
||||||
|
|
||||||
|
Lets assume the assets you are tracking on the blockchain ledger are trading cards. Each trading card represents a comic book character and has an id, size, favorite color, and owner.
|
||||||
|
These trading cards can be passed between people, with some cards having more 'value' due to rarity or having notable attributes.
|
||||||
|
|
||||||
|
In token terms, think of these cards as non-fungible tokens. Each card has different attributes and individual cards can't be subdivided.
|
||||||
|
|
||||||
|
We'll create a digital representation of these cards on the blockchain ledger. There are a few important aspects of this solution to consider:
|
||||||
|
|
||||||
|
- Ledger - The blockchain ledger on each peer maintains the current state of each card (asset), as well as the history of transactions that led to the current state, so that there is no doubt about the assets issuance, provenance, attributes, and ownership.
|
||||||
|
- Asset transfer smart contract - manage changes to asset state such as the transfer of cards between people
|
||||||
|
- Organizations - Since this is a permissioned blockchain we'll model the participants as organizations that are authorized to run nodes or transact on the Fabric network. Our simple network will consist of an ordering service organization and two transacting organizations.
|
||||||
|
- Ordering service organization - runs the ordering service to ensure transactions get ordered into blocks fairly, this may be a consortium leader or regulator in the industry. Note that ordering service nodes could also be contributed from multiple organizations, this becomes especially important when running a Byzantine Fault Tolerant (BFT) ordering service.
|
||||||
|
- Owner Organizations - Each owner organization is authorized to run peers and submit transfer transactions for the cards (assets) that they own.

||||||

|
If you do not want to install dependencies on your local environment, you can use a Multipass Ubuntu image instead.
|
||||||
|
|
||||||
|
Tip - You may need to stop any VPN client for the Multipass networking to work.
|
||||||
|
|
||||||
|
- [Install multipass](https://multipass.run/install)
|
||||||
|
|
||||||
|
- Launch the virtual machine and automatically install the workshop dependencies:
|
||||||
|
|
||||||
|
```shell
|
||||||
|
multipass launch \
|
||||||
|
--name fabric-dev \
|
||||||
|
--disk 80G \
|
||||||
|
--cpus 8 \
|
||||||
|
--mem 8G \
|
||||||
|
--cloud-init infrastructure/multipass-cloud-config.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
- Mount the local workshop to your multipass vm:
|
||||||
|
|
||||||
|
```shell
|
||||||
|
multipass mount $PWD fabric-dev:/home/ubuntu/full-stack-asset-transfer-guide
|
||||||
|
```
|
||||||
|
|
||||||
|
- Open a shell on the virtual machine:
|
||||||
|
|
||||||
|
```shell
|
||||||
|
multipass shell fabric-dev
|
||||||
|
```
|
||||||
|
|
||||||
|
Tip - The vm creation log can be seen at /var/log/cloud-init-output.log if you need to troubleshoot anything.
|
||||||
|
|
||||||
|
- You are now inside the virtual machine. cd to the workshop directory:
|
||||||
|
|
||||||
|
```shell
|
||||||
|
cd full-stack-asset-transfer-guide
|
||||||
|
```
|
||||||
|
|
||||||
|
- Install Fabric peer CLI and set environment variables
|
||||||
|
```shell
|
||||||
|
curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh
|
||||||
|
./install-fabric.sh binary
|
||||||
|
export WORKSHOP_PATH=$(pwd)
|
||||||
|
export PATH=${WORKSHOP_PATH}/bin:$PATH
|
||||||
|
export FABRIC_CFG_PATH=${WORKSHOP_PATH}/config
|
||||||
|
```
|
||||||
|
|
||||||
|
Note - You'll probably want three terminal windows for running the workshop, go ahead and open the shells now:
|
||||||
|
|
||||||
|
```shell
|
||||||
|
multipass shell fabric-dev
|
||||||
|
```
|
||||||
|
|
||||||
|
- Eventual cleanup - To remove the multipass image when you are done with it after the workshop:
|
||||||
|
```shell
|
||||||
|
multipass delete fabric-dev
|
||||||
|
multipass purge
|
||||||
|
multipass list
|
||||||
|
```
|
||||||
|
|
||||||
|

# Conga Cards
|
||||||
|
|
||||||
|
This Gateway Client application will listen for chaincode events, invoking a [#discord webhook](https://discord.com/developers/docs/resources/webhook)
|
||||||
|
to post a channel message when [Conga Cards](assets/) are created, deleted, and exchanged on a channel.
|
||||||
|
|
||||||
|
> [Conga Comics](https://congacomic.github.io) | Life on the chain, one block at a time by Ed Moffatt & some friends
|
||||||
|
|
||||||
|
This project is based on the [trader-typescript](../trader-typescript) sample Gateway Client application.
|
||||||
|
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
The client application requires Node.js 16 or later.
|
||||||
|
|
||||||
|
## Set up
|
||||||
|
|
||||||
|
The following steps prepare the client application for execution:
|
||||||
|
|
||||||
|
1. Ensure the [asset-transfer](../../contracts/asset-transfer-typescript/) smart contract is deployed to a running Fabric network.
|
||||||
|
1. Run `npm install` to download dependencies and compile the application code.
|
||||||
|
|
||||||
|
> **Note:** After making any code changes to the application, be sure to recompile the application code. This can be done by explicitly running `npm install` again, or you can leave `npm run build:watch` running in a terminal window to automatically rebuild the application on any code change.
|
||||||
|
|
||||||
|
|
||||||
|
The client application uses environment variables to supply configuration options. You must set the following environment variables when running the application:
|
||||||
|
|
||||||
|
- `ENDPOINT` - endpoint address for the Gateway service to which the client will connect in the form **hostname:port**. Depending on your environment, this can be the address of a specific peer within the user's organization, or an ingress endpoint that dispatches to any available peer in the user's organization.
|
||||||
|
- `MSP_ID` - member service provider ID for the user's organization.
|
||||||
|
- `CERTIFICATE` - PEM file containing the user's X.509 certificate.
|
||||||
|
- `PRIVATE_KEY` - PEM file containing the user's private key.
|
||||||
|
|
||||||
|
The following environment variables are optional and can be set if required by your environment:
|
||||||
|
|
||||||
|
- `CHANNEL_NAME` - Channel to which the chaincode is deployed. (Default: `mychannel`)
|
||||||
|
- `CHAINCODE_NAME` - Channel to which the chaincode is deployed. (Default: `asset-transfer`)
|
||||||
|
- `TLS_CERT` - PEM file containing the CA certificate used to authenticate the TLS connection to the Gateway peer. *Only required if using a TLS connection and a private CA.*
|
||||||
|
- `HOST_ALIAS` - the name of the Gateway peer as it appears in its TLS certificate. *Only required if the endpoint address used by the client does not match the address in the Gateway peer's TLS certificate.*
|
||||||
|
|
||||||
|
- `WEBHOOK_URL` - the [#discord webhook](https://discord.com/developers/docs/resources/webhook) to which the channel
|
||||||
|
events will be relayed.
|
||||||
|
|
||||||
|
|
||||||
|
# Run
|
||||||
|
|
||||||
|
The sample application is run as a command-line application, and is lauched using `npm start <command> [<arg> ...]`. The following commands are available:
|
||||||
|
|
||||||
|
- `npm start create <assetId> <ownerName> <color>` to create a new asset.
|
||||||
|
- `npm start delete <assetId>` to delete an existing asset.
|
||||||
|
- `npm start getAllAssets` to list all assets.
|
||||||
|
- `npm start read <assetId>` to view an existing asset.
|
||||||
|
- `npm start transfer <assetId> <ownerName> <ownerMspId>` to transfer an asset to a new owner within an organization MSP ID.
|
||||||
|
- `npm start discord` starts an event loop, relaying channel events to `${WEBHOOK_URL}`
|
||||||
|
|
||||||
|
|
||||||
|
## Sample Interaction:
|
||||||
|
|
||||||
|
- Submit some transactions to a ledger:
|
||||||
|
```shell
|
||||||
|
npm start create blockbert SeanB orange
|
||||||
|
|
||||||
|
npm start create count-blockula jkneubuhl Org1MSP purple
|
||||||
|
|
||||||
|
npm start transfer count-blockula davidboswell Org1MSP
|
||||||
|
```
|
||||||
|
|
||||||
|
- Run the discord event listener:
|
||||||
|
```shell
|
||||||
|
export WEBHOOK_URL="https://discord.com/api/webhooks/123456789/xyzzy-abcdef-12345"
|
||||||
|
|
||||||
|
npm start discord
|
||||||
|
```

# Trader sample client application
|
||||||
|
|
||||||
|
This is a simple client application for the [asset-transfer](../../contracts/asset-transfer-typescript/) smart contract, built using the [Fabric Gateway client API](https://hyperledger.github.io/fabric-gateway/) for Fabric v2.4+.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
The client application requires Node.js 16 or later.
|
||||||
|
|
||||||
|
## Set up
|
||||||
|
|
||||||
|
The following steps prepare the client application for execution:
|
||||||
|
|
||||||
|
1. Ensure the [asset-transfer](../../contracts/asset-transfer-typescript/) smart contract is deployed to a running Fabric network.
|
||||||
|
1. Run `npm install` to download dependencies and compile the application code.
|
||||||
|
|
||||||
|
> **Note:** After making any code changes to the application, be sure to recompile the application code. This can be done by explicitly running `npm install` again, or you can leave `npm run build:watch` running in a terminal window to automatically rebuild the application on any code change.
|
||||||
|
|
||||||
|
|
||||||
|
The client application uses environment variables to supply configuration options. You must set the following environment variables when running the application:
|
||||||
|
|
||||||
|
- `ENDPOINT` - endpoint address for the Gateway service to which the client will connect in the form **hostname:port**. Depending on your environment, this can be the address of a specific peer within the user's organization, or an ingress endpoint that dispatches to any available peer in the user's organization.
|
||||||
|
- `MSP_ID` - member service provider ID for the user's organization.
|
||||||
|
- `CERTIFICATE` - PEM file containing the user's X.509 certificate.
|
||||||
|
- `PRIVATE_KEY` - PEM file containing the user's private key.
|
||||||
|
|
||||||
|
The following environment variables are optional and can be set if required by your environment:
|
||||||
|
|
||||||
|
- `CHANNEL_NAME` - Channel to which the chaincode is deployed. (Default: `mychannel`)
|
||||||
|
- `CHAINCODE_NAME` - Channel to which the chaincode is deployed. (Default: `asset-transfer`)
|
||||||
|
- `TLS_CERT` - PEM file containing the CA certificate used to authenticate the TLS connection to the Gateway peer. *Only required if using a TLS connection and a private CA.*
|
||||||
|
- `HOST_ALIAS` - the name of the Gateway peer as it appears in its TLS certificate. *Only required if the endpoint address used by the client does not match the address in the Gateway peer's TLS certificate.*
|
||||||
|
|
||||||
|
# Run
|
||||||
|
|
||||||
|
The sample application is run as a command-line application, and is lauched using `npm start <command> [<arg> ...]`. The following commands are available:
|
||||||
|
|
||||||
|
- `npm start create <assetId> <ownerName> <color>` to create a new asset.
|
||||||
|
- `npm start delete <assetId>` to delete an existing asset.
|
||||||
|
- `npm start getAllAssets` to list all assets.
|
||||||
|
- `npm start listen` to listen for chaincode events emitted by transaction functions. Interrupt the listener using Control-C.
|
||||||
|
- `npm start read <assetId>` to view an existing asset.
|
||||||
|
- `npm start transact` to create some random assets and perform some random operations on those assets.
|
||||||
|
- `npm start transfer <assetId> <ownerName> <ownerMspId>` to transfer an asset to a new owner within an organization MSP ID.
