Blockchain Shop

Dependencies

• Docker
• Kubernetes (using kind - Kubernetes in Docker)

Getting Started

This repository sets up a Kubernetes cluster with a backend written in Go and a frontend written in Angular. Follow the steps below to get started.

Create the Cluster

First, navigate to the deployment directory and run the cluster.sh script to create the cluster.

cd deployment
./cluster.sh

This script will create a Kubernetes cluster with 1 master node and 2 worker nodes. All components will be deployed with the correct configurations.

Accessing the Backend API Documentation

Once the cluster is up and running, you can access the backend API documentation at:

http://localhost:30000/api/swagger/index.html

Managing the Blockchain

To manage the nodes and view information, you can connect to the node running on port 4000 inside the cluster. First, obtain the name of the pod running on node 4000 using the following command:

kubectl get pods

Look for a pod with a name similar to blockchain-backend-8669d87f94-zshfw.

Next, connect to the pod:

kubectl exec -it blockchain-backend-8669d87f94-zshfw -c blockchain-backend-4000 -- /bin/sh

Node Roles

• Node 3000: Generates the blockchain and acts as the main node.
• Node 4000: Manages the API and oversees the blockchain when all components are running.
• Node 5000: Functions as a miner node.
