Types

type Config

type Config struct {
	ManagementCluster ManagementClusterConfig `json:"managementCluster"`
	TargetCluster     TargetClusterConfig     `json:"targetCluster"`
	KubernetesVersion string                  `json:"kubernetesVersion"`
	UpgradeID         string                  `json:"upgradeID"`
	Patches           PatchConfig             `json:"patches"`
	MachineTimeout    metav1.Duration         `json:"machineTimeout"`
}

Config contains all the configurations necessary to upgrade a Kubernetes cluster.

type ControlPlaneUpgrader

type ControlPlaneUpgrader struct {
	// contains filtered or unexported fields
}

func NewControlPlaneUpgrader

func NewControlPlaneUpgrader(log logr.Logger, config Config) (*ControlPlaneUpgrader, error)

func (*ControlPlaneUpgrader) GetNodeFromProviderID

func (u *ControlPlaneUpgrader) GetNodeFromProviderID(providerID string) *v1.Node

func (*ControlPlaneUpgrader) UpdateProviderIDsToNodes

func (u *ControlPlaneUpgrader) UpdateProviderIDsToNodes() error

UpdateProviderIDsToNodes retrieves a map that pairs a providerID to the node by listing all Nodes providerID : Node

func (*ControlPlaneUpgrader) Upgrade

func (u *ControlPlaneUpgrader) Upgrade() error

Upgrade does the upgrading of the control plane.

type ManagementClusterConfig

type ManagementClusterConfig struct {
	// Kubeconfig is a path to a kubeconfig
	Kubeconfig string `json:"kubeconfig"`
	Context    string `json:"context"`
}

ManagementClusterConfig is the Kubeconfig and relevant information to connect to the management cluster of the worker cluster being upgraded.

type PatchConfig

type PatchConfig struct {
	Infrastructure   string `json:"infrastructure"`
	Bootstrap        string `json:"bootstrap"`
	KubeadmConfigMap string `json:"kubeadmConfigMap"`
}

PatchConfig contains JSON patch documents for modifying a Machine's referenced infrastructure and bootstrap resources.

type TargetClusterConfig

type TargetClusterConfig struct {
	Namespace string `json:"namespace"`
	Name      string `json:"name"`
}

TargetClusterConfig are all the necessary configs of the Kubernetes cluster being upgraded.
