Create a cluster

Prerequisites​

  • Install version 2.44.1 or newer of the Azure CLI. Note that your package manager will likely install an outdated version.
  • Install a recent version of kubectl.

Prepare using the AKS preview​

First, log in to your Azure subscription:

az login

CoCo on AKS is currently in preview. An extension for the az CLI is needed to create such a cluster. Add the extension with the following commands:

az extension add \
  --name aks-preview \
  --allow-preview true
az extension update \
  --name aks-preview \
  --allow-preview true

Then register the required feature flags in your subscription to allow access to the public preview:

az feature register \
    --namespace "Microsoft.ContainerService" \
    --name "KataCcIsolationPreview"

The registration can take a few minutes. The status of the operation can be checked with the following command, which should show the registration state as Registered:

az feature show \
    --namespace "Microsoft.ContainerService" \
    --name "KataCcIsolationPreview" \
    --output table

Afterward, refresh the registration of the ContainerService provider:

az provider register \
    --namespace "Microsoft.ContainerService"

Create resource group​

The AKS with CoCo preview is currently available in the following locations:

CentralIndia
eastus
EastUS2EUAP
GermanyWestCentral
japaneast
northeurope
SwitzerlandNorth
UAENorth
westeurope
westus

Set the name of the resource group you want to use:

azResourceGroup="ContrastDemo"

You can either use an existing one or create a new resource group with the following command:

azLocation="westus" # Select a location from the list above

az group create \
  --name "${azResourceGroup:?}" \
  --location "${azLocation:?}"

Create AKS cluster​

First, create a CoCo enabled AKS cluster with:

# Select the name for your AKS cluster
azClusterName="ContrastDemo"

az aks create \
  --resource-group "${azResourceGroup:?}" \
  --name "${azClusterName:?}" \
  --kubernetes-version 1.30 \
  --os-sku AzureLinux \
  --node-vm-size Standard_DC4as_cc_v5 \
  --workload-runtime KataCcIsolation \
  --node-count 1 \
  --generate-ssh-keys

Finally, update your kubeconfig with the credentials to access the cluster:

az aks get-credentials \
  --resource-group "${azResourceGroup:?}" \
  --name "${azClusterName:?}"

For validation, list the available nodes using kubectl:

kubectl get nodes

It should show a single node:

NAME                                STATUS   ROLES    AGE     VERSION
aks-nodepool1-32049705-vmss000000   Ready    <none>   9m47s   v1.29.0

🥳 Congratulations. You're now ready to set up your first application with Contrast. Follow this example to learn how.

Cleanup​

After trying out Contrast, you might want to clean up the cloud resources created in this step. In case you've created a new resource group, you can just delete that group with

az group delete \
  --name "${azResourceGroup:?}"

Deleting the resource group will also delete the cluster and all other related resources.

To only cleanup the AKS cluster and node pools, run

az aks delete \
  --resource-group "${azResourceGroup:?}" \
  --name "${azClusterName:?}"
