Azure: Create a Managed Cluster Using the DKP CLI

In the previous step, the new cluster was created as Self-managed which allows it to be a Management cluster. Subsequent new clusters are not self-managed as they will likely be Managed or Attached clusters to this Management Cluster.

When creating Managed clusters, you do not need to create and move CAPI objects, or install the Kommander component. Those tasks are only done on Management clusters!

Choose a Workspace for the New Cluster

1. If you have an existing Workspace name, run this command to find the name:
   ⚠️ NOTE: If you need to create a new Workspace, follow the instructions to Create a Workspace.

   CODE

   kubectl get workspace -A

2. When you have the Workspace name, set the WORKSPACE_NAMESPACE environment variable:

   CODE

   export WORKSPACE_NAMESPACE=<workspace_namespace>

Name your cluster

1. Give your cluster a unique name suitable for your environment.

2. Set the environment variable:

   CODE

   export CLUSTER_NAME=<azure-additional>

Use DKP CLI

Execute this command to create an additional cluster without self-managed flag:

dkp create cluster azure --cluster-name=${CLUSTER_NAME} --namespace=${WORKSPACE_NAMESPACE}

If your environment uses HTTP/HTTPS proxies, you must include the flags --http-proxy, --https-proxy, and --no-proxy and their related values in this command for it to be successful. More information is available in Configuring an HTTP/HTTPS Proxy.

Manually Attach a DKP CLI Cluster to the Management Cluster

1. Find out the name of the created Cluster, so you can reference it later:

   CODE

   kubectl -n <workspace_namespace> get clusters

2. Attach the cluster by creating a KommanderCluster:

   CODE

   cat << EOF | kubectl apply -f -
   apiVersion: kommander.mesosphere.io/v1beta1
   kind: KommanderCluster
   metadata:
     name: <cluster_name>
     namespace: <workspace_namespace>
   spec:
     kubeconfigRef:
       name: <cluster_name>-kubeconfig
     clusterRef:
       capiCluster:
         name: <cluster_name>
   EOF

You can also Create a new Azure Cluster Using the DKP UI.
