Bootstrap GCP

To create Kubernetes clusters, DKP uses Cluster API (CAPI) controllers. These controllers run on a Kubernetes cluster. To get started, you need a bootstrap cluster. By default, DKP 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.

Bootstrap Cluster Lifecycle Services

1. Review Universal Configurations for all Infrastructure Providers regarding settings, flags and other choices and then begin bootstrapping.

2. 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.

dkp create bootstrap --kubeconfig $HOME/.kube/config \
  --http-proxy <string> \
  --https-proxy <string> \
  --no-proxy <string>

3. The output looks similar to:

   BASH

    ✓ Creating a bootstrap cluster
    ✓ Initializing new CAPI components

4. DKP creates a bootstrap cluster using KIND as a library. DKP then deploys the following Cluster API providers on the cluster:

   • Core Provider

   • GCP Infrastructure Provider

   • Kubeadm Bootstrap Provider

   • Kubeadm ControlPlane Provider

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

   BASH

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

   You will then receive the following output:

   BASH
