  • Pick Azure Kubernetes Cluster provider.

Select Provider

  • Provide Credentials in either of the below mentioned ways:

    • Select a pre-created preset which stores the provider specific credentials.

    • Manually enter the credentials Tenant ID, Subscription ID, Client ID and Client Secret.

The credentials should provide access rights to read & write Azure Kubernetes Service and list cluster admin credential, in order to fetch kubeconfig using API. Learn about Authorize Resource Group

  • After user provides all required credentials, credentials will be validated.

Validation performed will only check if the credentials have Read access.

Cluster Details Page

After the cluster is added, the KKP controller retrieves the cluster kubeconfig to display all necessary information. A healthy cluster has Running state. Otherwise, the cluster can be in the Error state. Move the mouse cursor over the state indicator to get more details.

Upgrade AKS

If the version upgrade is valid, the cluster state will change to Reconciling.

Edit the Machine Deployment

Only one operation can be performed at one point of time. If the replica count is updated then Kubernetes version upgrade will be disabled and vice versa.

  • Navigate to the cluster overview, scroll down to machine deployments.

  • Click on the edit icon next to the machine deployment you want to edit.

Update AKS Machine Deployment

  • Upgrade Kubernetes Version. Select the Kubernetes Version from the dropdown to upgrade the machine deployment.

Cluster State

Provisioning State is used to indicate AKS Cluster State This represents the state of the last operation attempted on this node pool, such as scaling the number of nodes or upgrading the Kubernetes version. The nodes may still be running even if this state is showing as ‘Failed’. Check previous operations on the node pool to resolve any failures.

If the cluster is stopped from the Azure side, you will be able to see the current state of the cluster as stopped. Cluster details will not be visible as the details are fetched using kubeconfig, and the kubeconfig is not available for the stopped cluster.
