Azure

Cluster access​

Install azure cli​

In order to be able to import he cluster config we need to install the cli

powershell
  $ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://aka.ms/installazurecliwindows -OutFile .\AzureCLI.msi; Start-Process msiexec.exe -Wait -ArgumentList '/I AzureCLI.msi /quiet'; rm .\AzureCLI.msi

After installing the azure cli we need to add the AKS plugins

aks plugins
az aks install-cli

Now we are all set

Get Cluster config​

To get our cluster config we first need to login to azure

login
az login

This will open a login window where we can perform the login.

Configure kubectl to connect to your Kubernetes cluster using the az aks get-credentials command. The following command:

Downloads credentials and configures the Kubernetes CLI to use them. Uses ~/.kube/config, the default location for the Kubernetes configuration file. Specify a different location for your Kubernetes configuration file using --file argument.

azure cli
az aks get-credentials --resource-group <myResourceGroup> --name <myAKSCluster>

Creating a cluster​

The easiest way to create a cluster is to use the cli

Here is a basic example of how to create cluster. There are many more options available for more details see the AKS docs

az aks create \
  -g myResourceGroup \ 
  -n myAKSCluster \ 
  --enable-managed-identity \
  --node-count 1 \
  --node-vm-size Standard_DS2_v2 \
  --enable-addons monitoring \
  --enable-msi-auth-for-monitoring  \
  --kubernetes-version 1.24.6  \
  --generate-ssh-keys

Storage classes​

Storage classes are important when using persistent volumes. Azure provides a wide variety of storage classes when the cluster is created, but the standard reclaim policy is always set to delete. If we want our volume to remain after the pod has been deleted then we need to create our own storage classes.

We will be defining two storage classes.

  • managed-csi-retain
  • managed-csi-premium-retain
storage classes
kubectl apply -f - <<EOF
apiVersion: storage.k8s.io/v1
