Pre-provisioned Bootstrap Cluster

Konvoy deploys all cluster lifecycle services to a bootstrap cluster, which deploys a workload cluster. When the workload cluster is ready, move the cluster lifecycle services to the workload cluster. The workload cluster then manages its own lifecycle.

To create Kubernetes clusters, Konvoy uses Cluster API (CAPI) controllers. These controllers run on a Kubernetes cluster. To get started, you need a bootstrap cluster. By default, Konvoy creates a bootstrap cluster for you in a Docker container using the Kubernetes-in-Docker (KIND) tool.

Prerequisites

Before you begin, you must:

Complete the steps in Prerequisites.
Ensure the dkp binary can be found in your $PATH.
IF using a Registry Mirror even though you are not in an air-gapped environment, refer to the air-gapped section for loading images: Pre-provisioned Air-gapped Define Environment

Bootstrap Cluster Lifecycle Services

Review Universal Configurations for all Infrastructure Providers regarding settings, flags and other choices and then begin bootstrapping.
Create a bootstrap cluster:
YAML
```
dkp create bootstrap --kubeconfig $HOME/.kube/config
```
- Configuring an HTTP/HTTPS Proxy use --http-proxy, --https-proxy, and --no-proxy and their related values in this command for it to be successful.

HTTP Flags if needed:

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>

Output:

 ✓ Creating a bootstrap cluster
 ✓ Initializing new CAPI components

Konvoy creates a bootstrap cluster using KIND as a library and deploys Cluster API providers on the cluster. Refer to Customizing CAPI Components for a Clusterfor more details.

Konvoy waits until the controller-manager and webhook deployments of these providers are ready. List these deployments using this command:

YAML

kubectl get --all-namespaces deployments -l=clusterctl.cluster.x-k8s.io

Output:
