Cluster API vSphere Provider

Delete Cluster

This guide explains how to delete all resources that were created as part of your Cluster API Kubernetes cluster.

The provider currently only creates resources specified in the named machine config map. The default examples only provision VMs. If your custom HCL config configures load balancers, or provisions other resources, amend this guide as necessary.

1. Delete all of the node Machines in the cluster. Make sure to wait for the corresponding Nodes to be deleted before moving onto the next step. After this step, the master node will be the only remaining node.

kubectl delete machines -l set=node
kubectl get nodes

1. Delete the VM that is running your cluster's control plane. You can either do this from the vCenter UI or using govc.

govc vm.destroy --dc=$VSPHERE-DC $VM-NAME

Functions

func CreateApiServerAndController

func CreateApiServerAndController(token string) error

func CreateExtApiServerRoleBinding

func CreateExtApiServerRoleBinding() error

TODO: We need to change this when we create dedicated service account for apiserver/controller pod.

func PreloadMasterScript

func PreloadMasterScript(version string, dockerImages []string) (string, error)

PreloadMasterScript returns a script that can be used to preload a master.

func PreloadNodeScript

func PreloadNodeScript(version string, dockerImages []string) (string, error)

PreloadNodeScript returns a script that can be used to preload a master.

Types

type DeploymentClient

type DeploymentClient struct{}

Contains vsphere-specific deployment logic intended to eventually implement ProviderDeployer interface at sigs.k8s.io/cluster-api/clusterctl/clusterdeployer/clusterdeployer.go Currently implements a subset of the machineDeployer interface at sigs.k8s.io/cluster-api/vsphere-deployer/deploy/machinedeployer.go till vsphere-deployer gets deleted

func NewDeploymentClient

func NewDeploymentClient() *DeploymentClient

func (*DeploymentClient) GetIP

func (*DeploymentClient) GetIP(machine *clusterv1.Machine) (string, error)

func (*DeploymentClient) GetKubeConfig

func (d *DeploymentClient) GetKubeConfig(master *clusterv1.Machine) (string, error)

type VsphereClient

type VsphereClient struct {

	// Once the vsphere-deployer is deleted, both DeploymentClient and VsphereClient can depend on
	// something that implements GetIP instead of the VsphereClient depending on DeploymentClient.
	*DeploymentClient
	// contains filtered or unexported fields
}
