vSphere Create an Air-gapped Bootstrap Cluster

Prerequisites

Before you perform this procedure, ensure that you have created a CAPI VM template.

If an HTTP proxy is required for the bootstrap cluster, set the local http_proxy, https_proxy, and no_proxy environment variables. They are copied into the bootstrap cluster.

Create a bootstrap cluster:

CODE

dkp create bootstrap --kubeconfig $HOME/.kube/config

The output resembles this example:

CODE

✓ Creating a bootstrap cluster
✓ Initializing new CAPI components

HTTP Only flags:

To create a bootstrap cluster in a proxied environment use this command syntax, in addition to any other flags you may need:

CODE

  --http-proxy <string> \
  --https-proxy <string> \
  --no-proxy <string>

Flatcar OS use --os-hint to instruct the bootstrap cluster to make some changes related to the installation paths:
CODE
```
--os-hint flatcar
```

The output resembles this example:

CODE

✓ Creating a bootstrap cluster
✓ Initializing new CAPI components

Ensure that the CAPV controllers are present with the command:

CODE

kubectl get pods -n capv-system

The output resembles the following:

CODE

NAME                                      READY   STATUS    RESTARTS   AGE
