+# Create AKS Cluster
+
+## Step-01: Introduction
+- Understand about AKS Cluster
+- Discuss about Kubernetes Architecture from AKS Cluster perspective
+
+## Step-02: Create AKS Cluster
+- Create Kubernetes Cluster
+- **Basics**
+ - **Subscription:** Free Trial
+ - **Resource Group:** Creat New: aks-rg1
+ - **Kubernetes Cluster Name:** aksdemo1
+ - **Region:** (US) Central US
+ - **Kubernetes Version:** Select what ever is latest stable version
+ - **Node Size:** Standard DS2 v2 (Default one)
+ - **Node Count:** 1
+- **Node Pools**
+ - leave to defaults
+- **Authentication**
+ - Authentication method:	System-assigned managed identity
+ - Rest all leave to defaults
+- **Networking**
+ - **Network Configuration:** Advanced
+ - **Network Policy:** Azure
+ - Rest all leave to defaults
+- **Integrations**
+ - Azure Container Registry: None
+ - leave to defaults
+- **Tags**
+ - leave to defaults
+- **Review + Create**
+ - Click on **Create**
+
+
+## Step-03: Cloud Shell - Configure kubectl to connect to AKS Cluster
+- Go to https://shell.azure.com
+```
+# Template
+az aks get-credentials --resource-group <Resource-Group-Name> --name <Cluster-Name>
+
+# Replace Resource Group & Cluster Name
+az aks get-credentials --resource-group aks-rg1 --name aksdemo1
+
+# List Kubernetes Worker Nodes
+kubectl get nodes 
+kubectl get nodes -o wide
+```
+
+## Step-04: Explore Cluster Control Plane and Workload inside that
+```
+# List Namespaces
+kubectl get namespaces
+kubectl get ns
+
+# List Pods from all namespaces
+kubectl get pods --all-namespaces
+
+# List all k8s objects from Cluster Control plane
+kubectl get all --all-namespaces
+```
+
+## Step-05: Explore the AKS cluster on Azure Management Console
+- Explore the following features on high-level
+- **Overview**
+ - Activity Log
+ - Access Control (IAM)
+ - Security
+ - Diagnose and solver problems
+- **Settings**
+ - Node Pools
+ - Upgrade
+ - Scale
+ - Networking
+ - DevSpaces
+ - Deployment Center
+ - Policies
+- **Monitoring**
+ - Insights
+ - Alerts
+ - Metrics
+ - and many more 
+- **VM Scale Sets**
+ - Verify Azure VM Instances
+ - Verify if **Enhanced Networking is enabled or not** 
+
+
+
+## Step-06: Local Desktop - Install Azure CLI and Azure AKS CLI
+```
+# Install Azure CLI (MAC)
+brew update && brew install azure-cli
+
+# Login to Azure
+az login
+
+# Install Azure AKS CLI
+az aks install-cli
+
+# Configure Cluster Creds (kube config)
+az aks get-credentials --resource-group aks-rg1 --name aksdemo1
+
+# List AKS Nodes
+kubectl get nodes 
+kubectl get nodes -o wide
+```
+- **Reference Documentation Links**
+- https://docs.microsoft.com/en-us/cli/azure/?view=azure-cli-latest
+- https://docs.microsoft.com/en-us/cli/azure/aks?view=azure-cli-latest
+
+## Step-07: Deploy Sample Application and Test
+- Don't worry about what is present in these two files for now. 
+- By the time we complete **Kubernetes Fundamentals** sections, you will be an expert in writing Kubernetes manifest in YAML.
+- For now just focus on result. 
+```
+# Deploy Application
+kubectl apply -f kube-manifests/
+
+# Verify Pods
+kubectl get pods
+
+# Verify Deployment
+kubectl get deployment
+
+# Verify Service (Make a note of external ip)
+kubectl get service
+
+# Access Application
+http://<External-IP-from-get-service-output>
+```
+
+## Step-07: Clean-Up
+```
+# Delete Applications
+kubectl delete -f kube-manifests/
