Types

type ClusterError

type ClusterError struct {
	Reason  ClusterStatusError
	Message string
}

ClusterError is a more descriptive kind of error that represents an error condition that should be set in the Cluster.Status. The "Reason" field is meant for short, enum-style constants meant to be interpreted by clusters. The "Message" field is meant to be read by humans.

func CreateCluster

func CreateCluster(format string, args ...interface{}) *ClusterError

CreateCluster creates a new error for when creating a cluster.

func DeleteCluster

func DeleteCluster(format string, args ...interface{}) *ClusterError

DeleteCluster creates a new error for when deleting a cluster.

func InvalidClusterConfiguration

func InvalidClusterConfiguration(format string, args ...interface{}) *ClusterError

InvalidClusterConfiguration creates a new error for when the cluster configuration is invalid.

func (*ClusterError) Error

func (e *ClusterError) Error() string

type ClusterStatusError

type ClusterStatusError string

ClusterStatusError defines errors states for Cluster objects.

const (
	// InvalidConfigurationClusterError indicates that the cluster
	// configuration is invalid.
	InvalidConfigurationClusterError ClusterStatusError = "InvalidConfiguration"

	// UnsupportedChangeClusterError indicates that the cluster
	// spec has been updated in an unsupported way. That cannot be
	// reconciled.
	UnsupportedChangeClusterError ClusterStatusError = "UnsupportedChange"

	// CreateClusterError indicates that an error was encountered
	// when trying to create the cluster.

	// UpdateClusterError indicates that an error was encountered
	// when trying to update the cluster.

type KubeadmControlPlaneError

type KubeadmControlPlaneError struct {
	Reason  KubeadmControlPlaneStatusError
	Message string
}

KubeadmControlPlaneError is a more descriptive kind of error that represents an error condition that should be set in the KubeadmControlPlane.Status. The "Reason" field is meant for short, enum-style constants meant to be interpreted by control planes. The "Message" field is meant to be read by humans.

func (*KubeadmControlPlaneError) Error

Error satisfies the error interface.

type KubeadmControlPlaneStatusError

type KubeadmControlPlaneStatusError string

KubeadmControlPlaneStatusError defines errors states for KubeadmControlPlane objects.

const (
	// InvalidConfigurationKubeadmControlPlaneError indicates that the kubeadm control plane
	// configuration is invalid.
	InvalidConfigurationKubeadmControlPlaneError KubeadmControlPlaneStatusError = "InvalidConfiguration"

	// UnsupportedChangeKubeadmControlPlaneError indicates that the kubeadm control plane
	// spec has been updated in an unsupported way that cannot be
	// reconciled.
	UnsupportedChangeKubeadmControlPlaneError KubeadmControlPlaneStatusError = "UnsupportedChange"

	// CreateKubeadmControlPlaneError indicates that an error was encountered
	// when trying to create the kubeadm control plane.
	CreateKubeadmControlPlaneError KubeadmControlPlaneStatusError = "CreateError"

	// UpdateKubeadmControlPlaneError indicates that an error was encountered
	// when trying to update the kubeadm control plane.
	UpdateKubeadmControlPlaneError KubeadmControlPlaneStatusError = "UpdateError"

	// DeleteKubeadmControlPlaneError indicates that an error was encountered
	// when trying to delete the kubeadm control plane.
	DeleteKubeadmControlPlaneError KubeadmControlPlaneStatusError = "DeleteError"
)

type MachineError

type MachineError struct {
	Reason  MachineStatusError
	Message string
}

MachineError is a more descriptive kind of error that represents an error condition that should be set in the Machine.Status. The "Reason" field is meant for short, enum-style constants meant to be interpreted by machines. The "Message" field is meant to be read by humans.

func CreateMachine

func CreateMachine(msg string, args ...interface{}) *MachineError

CreateMachine creates a new error for when creating a Machine.

func DeleteMachine

func DeleteMachine(msg string, args ...interface{}) *MachineError

DeleteMachine creates a new error for when deleting a Machine.

func InvalidMachineConfiguration

func InvalidMachineConfiguration(msg string, args ...interface{}) *MachineError

InvalidMachineConfiguration creates a new error when a Machine has invalid configuration.

func UpdateMachine

func UpdateMachine(msg string, args ...interface{}) *MachineError

UpdateMachine creates a new error for when updating a Machine.

func (*MachineError) Error

func (e *MachineError) Error() string

type MachinePoolStatusFailure

type MachinePoolStatusFailure string

MachinePoolStatusFailure defines errors states for MachinePool objects.

const (
	// InvalidConfigurationMachinePoolError represemts
	// the combination of configuration in the MachineTemplateSpec
	// is not supported by this cluster. This is not a transient error, but
	// indicates a state that must be fixed before progress can be made.
	//
	// Example: the ProviderSpec specifies an instance type that doesn't exist.
	InvalidConfigurationMachinePoolError MachinePoolStatusFailure = "InvalidConfiguration"
)

func MachinePoolStatusErrorPtr

func MachinePoolStatusErrorPtr(v MachinePoolStatusFailure) *MachinePoolStatusFailure

MachinePoolStatusErrorPtr converts a MachinePoolStatusError to a pointer.

type MachineSetStatusError

type MachineSetStatusError string

MachineSetStatusError defines errors states for MachineSet objects.

const (
	// InvalidConfigurationMachineSetError represents
	// the combination of configuration in the MachineTemplateSpec
	// is not supported by this cluster. This is not a transient error, but
	// indicates a state that must be fixed before progress can be made.
	//
	// Example: the ProviderSpec specifies an instance type that doesn't exist.
	InvalidConfigurationMachineSetError MachineSetStatusError = "InvalidConfiguration"
)

type MachineStatusError

type MachineStatusError string

MachineStatusError defines errors states for Machine objects.

const (
	// InvalidConfigurationMachineError represents that the combination
	// of configuration in the MachineSpec is not supported by this cluster.
	// This is not a transient error, but
	// indicates a state that must be fixed before progress can be made.
	//
	// Example: the ProviderSpec specifies an instance type that doesn't exist,.
	InvalidConfigurationMachineError MachineStatusError = "InvalidConfiguration"

	// UnsupportedChangeMachineError indicates that the MachineSpec has been updated in a way that
	// is not supported for reconciliation on this cluster. The spec may be
	// completely valid from a configuration standpoint, but the controller
	// does not support changing the real world state to match the new
	// spec.
	//
	// Example: the responsible controller is not capable of changing the
	// container runtime from docker to rkt.
	UnsupportedChangeMachineError MachineStatusError = "UnsupportedChange"

	// InsufficientResourcesMachineError generally refers to exceeding one's quota in a cloud provider,
	// or running out of physical machines in an on-premise environment.
	InsufficientResourcesMachineError MachineStatusError = "InsufficientResources"

	// CreateMachineError indicates an error while trying to create a Node to match this
	// Machine. This may indicate a transient problem that will be fixed
	// automatically with time, such as a service outage, or a terminal
	// error during creation that doesn't match a more specific
	// MachineStatusError value.
	//
	// Example: timeout trying to connect to GCE.
	CreateMachineError MachineStatusError = "CreateError"

	// UpdateMachineError indicates an error while trying to update a Node that this
	// Machine represents. This may indicate a transient problem that will be
	// fixed automatically with time, such as a service outage,
	//
	// Example: error updating load balancers.
	UpdateMachineError MachineStatusError = "UpdateError"

	// DeleteMachineError indicates an error was encountered while trying to delete the Node that this
	// Machine represents. This could be a transient or terminal error, but
	// will only be observable if the provider's Machine controller has
	// added a finalizer to the object to more gracefully handle deletions.
	//
	// Example: cannot resolve EC2 IP address.
	DeleteMachineError MachineStatusError = "DeleteError"

	// JoinClusterTimeoutMachineError indicates that the machine did not join the cluster
	// as a new node within the expected timeframe after instance
	// creation at the provider succeeded
	//
	// Example use case: A controller that deletes Machines which do
	// not result in a Node joining the cluster within a given timeout
	// and that are managed by a MachineSet.
	JoinClusterTimeoutMachineError = "JoinClusterTimeoutError"

func MachineStatusErrorPtr

func MachineStatusErrorPtr(v MachineStatusError) *MachineStatusError

MachineStatusErrorPtr converts a MachineStatusError to a pointer.
