vSphere Explore your Air-gapped Cluster

Find and Change Configurations

Your newly created cluster has many components to explore that are described below.

Get the kubeconfig File for the New Kubernetes Cluster

  1. Fetch the kubeconfig file with the command:

    CODE
    dkp get kubeconfig -c ${air-gapped_NAME} > ${air-gapped_NAME}.conf

Create a StorageClass with a vSphere Datastore

Follow these steps:

  1. Access the Datastore tab in the vSphere client and select a datastore by name.

  2. Copy the URL of that datastore from the information dialog that displays.

  3. Return to the DKP CLI, and delete the existing StorageClass with the command:

    CODE
    kubectl delete storageclass vsphere-raw-block-sc
  4. Run the following command to create a new StorageClass, supplying the correct values for your environment:

    CODE
    cat <<EOF > vsphere-raw-block-sc.yaml
    kind: StorageClass
    apiVersion: storage.k8s.io/v1
    metadata:
      annotations:
        storageclass.kubernetes.io/is-default-class: "true"
      name: vsphere-raw-block-sc
    provisioner: csi.vsphere.vmware.com
    parameters:
      datastoreurl: "<url>"
    volumeBindingMode: WaitForFirstConsumer
    EOF

Explore Nodes and Pods in the New Cluster

  1. List the Nodes with this command:

    CODE
    kubectl --kubeconfig=${air-gapped_NAME}.conf get nodes

NOTE: It may take a few minutes for the Status to move to Ready while the Pod network is deployed. The Node's Status should change to Ready soon after the calico-node DaemonSet Pods are Ready.

The output resembles this example:

CODE
NAME                                         STATUS   ROLES                  AGE   VERSION
d2iq-e2e-air-gapped-1-control-plane-7llgd     Ready    control-plane,master   20h   v1.28.7
d2iq-e2e-air-gapped-1-control-plane-vncbl     Ready    control-plane,master   19h   v1.28.7
d2iq-e2e-air-gapped-1-control-plane-wbgrm     Ready    control-plane,master   19h   v1.28.7
d2iq-e2e-air-gapped-1-md-0-74c849dc8c-67rv4   Ready    <none>                 19h   v1.28.7
d2iq-e2e-air-gapped-1-md-0-74c849dc8c-n2skc   Ready    <none>                 19h   v1.28.7
d2iq-e2e-air-gapped-1-md-0-74c849dc8c-nkftv   Ready    <none>                 19h   v1.28.7
d2iq-e2e-air-gapped-1-md-0-74c849dc8c-sqklv   Ready    <none>                 19h   v1.28.7

2. List the pods with the command:

CODE
kubectl --kubeconfig=${air-gapped_NAME}.conf get pods -A

The output resembles the following example:

CODE
NAMESPACE                NAME                                                                 READY   STATUS     RESTARTS      AGE
