Kubernetes has come to change the world of Microservices. Azure makes Kubernetes Orchestration a breeze with their Azure Kubernetes Services. In this step by step tutorial, I show you how to create your first Kubernetes Cluster on Azure. Before we proceed, may I indulge you with a post I created a little while ago on Azure Networking?

Step 1: create an azure kubernetes service resource on azure

Step 2: create an azure kubernetes service cluster

Step 3: create a kubernetes cluster

Step 3: create a kubernetes cluster specify resource group

Step 4: create a kubernetes cluster name

Step 5: create a kubernetes cluster kubernetes version

Step 6: create a kubernetes cluster choose a vm size

Step 7: create a kubernetes cluster enable virtual machine scale sets

Step 8: create a kubernetes cluster – validation passed

Step 9: create a kubernetes cluster – deployment

Step 10: create a kubernetes cluster – deployment complete

How to Create AKS Cluster – Working via the Shell

Connect to your cluster using command line tooling to interact directly with cluster using kubectl, the command line tool for Kubernetes. Kubectl is available within the Azure Cloud Shell by default and can also be installed locally

az account set --subscription 938f58d6-a922-40d0-b7b2-7068c5392eaf 

az aks get-credentials --resource-group learn-503b25e2-82da-40c1-a257-35aeaa9614ae --name aks-workload-westus

# List all deployments in all namespaces

kubectl get deployments --all-namespaces=true

# List all deployments in a specific namespace
# Format :kubectl get deployments –namespace

kubectl get deployments --namespace kube-system

# List details about a specific deployment
# Format :kubectl describe deployment –namespace

kubectl describe deployment my-dep --namespace kube-system

# List pods using a specific label
# Format :kubectl get pods -l = –all-namespaces=true

kubectl get pods -l app=nginx --all-namespaces=true

# Get logs for all pods with a specific label
# Format :kubectl logs -l =

kubectl logs -l app=nginx --namespace kube-system

With your AKS Cluster now deployed, kubernetes commands can now be issued.
