Azure-cluster

Create Azure (AKS) cluster

AKS is a free container service where nothing will be charged for Kubernetes cluster management. You'll have to pay only for the cloud resources such as VMs, storage, and network resources.

Required for this workshop

You need an Azure Account with payment Subscription to execute this workshop.

Warning Microsoft will charge you a small fee when executing the steps in the workshop (3 instances of type Standard_DS2_v2 used)! Cost will be minimized as we will upgrasde to a free plan. We strongly recomend to clean up the cluster after this demo! Clean up steps are included in this demo.

Cloud shell

All commands exercise are executed into Azure Cloud shell. Azure Cloud Shell requires an Azure file share to persist files. Create one if requested. Here is walkthrough how to setup Azure Cloud Shell

Open cloud shell

Create a new storage account

Let's set a environment variable for the location where we will use to start the resources.

List available locations

To see all possible locations enter the following:

az account list-locations -o table

Set default location

Replace {name of your location} with the location where your current storage account is located.

az configure --defaults location={name of your location}

Before we can start with deploying our Azure Kubernetes Cluster we first have to create a resource group:

az group create --name rg-Workshop-K8S

Install Helm

Helm is a tool that streamlines installing and managing Kubernetes applications and resources. Click here to read more about Helm.

export VERIFY_CHECKSUM=false && \
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash && \
chmod +x ./get_helm.sh && \
./get_helm.sh

Here is a sample installation output:

Downloading https://get.helm.sh/helm-v3.5.4-linux-amd64.tar.gz
Verifying checksum... Done.
Preparing to install helm into /usr/local/bin
helm installed into /usr/local/bin/helm

Verify that helm is working:

helm version

Output

version.BuildInfo{Version:"v3.5.4", GitCommit:"1b5edb69df3d3a08df77c9902dc17af864ff05d1", GitTreeState:"clean", GoVersion:"go1.15.11"}

Now that we have the resource group created, we can start with the deploying of the AKS-cluster.

Create cluster

az aks create --resource-group rg-Workshop-K8S --name Workshop-K8S --generate-ssh-keys

Note After about 5~10 min the cluster should be deployed

Get credentials to allow you to access the cluster with kubectl

Using the switch --admin or -a admin credentials are added. Default is user credentials

az aks get-credentials --resource-group rg-Workshop-K8S --name Workshop-K8S

Verify AKS cluster has started

kubectl get nodes
