📘 Documentation: Deploy Robot-Shop Application on Azure AKS using Helm

1️⃣ Prerequisites

System Requirements

• Windows machine

• PowerShell (run as Administrator)

• Azure subscription with AKS permissions

Tools Required

• Azure CLI

• kubectl

• Helm

• Chocolatey (for Windows package management)

2️⃣ Install Chocolatey (Windows Package Manager)

Set-ExecutionPolicy Bypass -Scope Process -Force
[System.Net.ServicePointManager]::SecurityProtocol = 3072
iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

Verify:

choco --version

3️⃣ Install Helm using Chocolatey

choco install kubernetes-helm -y

Verify:

helm version

4️⃣ Login to Azure

az login

Select the correct subscription when prompted.

Verify AKS exists:

az aks list -o table

5️⃣ Configure kubectl for AKS Cluster (IMPORTANT STEP)

❗ Most errors earlier happened because kubeconfig was not set

az aks get-credentials `
  --resource-group ecommercedemopractice `
  --name ecommerceAKS `
  --overwrite-existing

Verify connection:

kubectl get nodes

✅ You should see nodes in Ready state.

6️⃣ Navigate to Helm Chart Directory

cd C:\Users\<your-user>\downloads\three-tier-architecture-demo\AKS\helm

Make sure Chart.yaml exists:

ls

7️⃣ Deploy Robot-Shop Application using Helm

Basic Installation (creates namespace automatically)

helm install robot-shop . `
  --namespace robot-shop `
  --create-namespace

Verify:

kubectl get pods -n robot-shop

The Application is Stan Robot Shop this is three tier architecture with different micro services

The Microservices are

1.User Microservice-user db

2.Catalogue Microservice—Different product each has different details and price

3.Cart Microservice—add the items in carts

4.Payment Microservice

5.Shipping Microservice-Calculating the price of shipping based on distance etc

6.Dispatch Microservice-ready to deliver

7.Web Microservice—User interface [Nginix]

8.Ratings Microservice—need to be store in data store in memory data storage i.e Redis
datastore-persistant volume in stateful it will come all the previously stored volume

• Databases:

• “Databases are broadly classified into relational and non-relational. Relational databases ensure strong consistency using structured schemas, while NoSQL databases provide scalability and flexibility for distributed systems.”

• Relational :These store data in tables (rows & columns) and use SQL.

  • MySQL

  • PostgreSQL

  • Microsoft SQL Server

  • Oracle Database

  • MariaDB

  • SQLite

Used for: banking, finance, ERP, CRM systems

• Used when high scale, flexibility, and performance are required.

• Non Relational:Mangodb,couchdb,azurecosmosdb

• Databases used in the project

  Mysql Database:

• Mongo DB :

• 1.create the AKS

• az aks create --resource-group ecommercedemopractice --name ecommerceAKS --node-count 1 --node-vm-size Standard_b2ps_v2 --enable-managed-identity --generate-ssh-keys

az aks get-credentials --resource-group ecommercedemopractice --name ecommerceAKS

PS C:\Users\91967\downloads\three-tier-architecture-demo> az aks get-credentials --resource-group ecommercedemopractice --name ecommerceAKS

PS C:\Users\91967\downloads\three-tier-architecture-demo> az aks get-credentials --resource-group ecommercedemopractice --name ecommerceAKS

Merged "ecommerceAKS" as current context in C:\Users\91967\.kube\config

PS C:\Users\91967\downloads\three-tier-architecture-demo> kubectl get pods

No resources found in default namespace.

PS C:\Users\91967\downloads\three-tier-architecture-demo> kubectl config current-context

to reconnect again

az aks get-credentials --resource-group ecommercedemopractice --name ecommerceAKS --overwrite-existing

• 2.need to follow some command to get the aks connect with the terminal
