Types

type KubeconfigProvider

type KubeconfigProvider interface {
	GetKubeconfig(context.Context, *zap.SugaredLogger) (*clientcmdapi.Config, error)
	GetBearerToken() string
}

type MachineCollector

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

func NewMachineCollector

func NewMachineCollector(ctx context.Context, client ctrlruntimeclient.Client) *MachineCollector

func (MachineCollector) Collect

func (mc MachineCollector) Collect(ch chan<- prometheus.Metric)

Collect implements the prometheus.Collector interface.

func (MachineCollector) Describe

func (mc MachineCollector) Describe(ch chan<- *prometheus.Desc)

Describe implements the prometheus.Collector interface.

type MetricsCollection

type MetricsCollection struct {
	Workers        prometheus.Gauge
	Errors         prometheus.Counter
	Provisioning   prometheus.Histogram
	Deprovisioning prometheus.Histogram
}

MetricsCollection is a struct of all metrics used in this controller.

func NewMachineControllerMetrics

func NewMachineControllerMetrics() *MetricsCollection

NewMachineControllerMetrics creates new MachineControllerMetrics with default values initialized, so metrics always show up.

func (*MetricsCollection) MustRegister

func (mc *MetricsCollection) MustRegister(registerer prometheus.Registerer)

type NodeSettings

type NodeSettings struct {
	// Translates to --cluster-dns on the kubelet.
	ClusterDNSIPs []net.IP
	// If set, this proxy will be configured on all nodes.
	HTTPProxy string
	// If set this will be set as NO_PROXY on the node.
	NoProxy string
	// If set, those registries will be configured as insecure on the container runtime.
	InsecureRegistries []string
	// If set, these mirrors will be take for pulling all required images on the node.
	RegistryMirrors []string
	// Translates to --pod-infra-container-image on the kubelet. If not set, the kubelet will default it.
	PauseImage string
	// Translates to feature gates on the kubelet.
	// Default: RotateKubeletServerCertificate=true
	KubeletFeatureGates map[string]bool
	// Used to set kubelet flag --cloud-provider=external
	ExternalCloudProvider bool
	// container runtime to install
	ContainerRuntime containerruntime.Config
	// Registry credentials secret object reference
	RegistryCredentialsSecretRef string
}

type Reconciler

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

Reconciler is the controller implementation for machine resources.

func (*Reconciler) ReadinessChecks

func (r *Reconciler) ReadinessChecks(ctx context.Context) map[string]healthcheck.Check

func (*Reconciler) Reconcile

func (r *Reconciler) Reconcile(ctx context.Context, request reconcile.Request) (reconcile.Result, error)
