RollingUpdateCluster is a struct containing cluster information for a rolling update.

func (*RollingUpdateCluster) AdjustNeedUpdate

func (*RollingUpdateCluster) AdjustNeedUpdate(groups map[string]*cloudinstances.CloudInstanceGroup) error

AdjustNeedUpdate adjusts the set of instances that need updating, using factors outside those known by the cloud implementation

func (*RollingUpdateCluster) RollingUpdate

func (c *RollingUpdateCluster) RollingUpdate(groups map[string]*cloudinstances.CloudInstanceGroup, instanceGroups *api.InstanceGroupList) error

RollingUpdate performs a rolling update on a K8s Cluster.

func (*RollingUpdateCluster) UpdateSingleInstance

func (c *RollingUpdateCluster) UpdateSingleInstance(cloudMember *cloudinstances.CloudInstance, detach bool) error

UpdateSingleInstance performs a rolling update on a single instance

type RollingUpdateOptions

type RollingUpdateOptions struct {
	// DeregisterControlPlaneNodes controls if we deregister control plane instances from load balacners etc before draining/terminating.
	// When a cluster only has a single apiserver, we don't want to do this, as we can't drain after deregistering it.
	DeregisterControlPlaneNodes bool
}

func (*RollingUpdateOptions) InitDefaults

func (o *RollingUpdateOptions) InitDefaults()

type ValidationTimeoutError

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

ValidationTimeoutError represents an error that occurs when the cluster fails to validate within the designated timeout.

func (*ValidationTimeoutError) Error

func (v *ValidationTimeoutError) Error() string

func (*ValidationTimeoutError) Is

func (v *ValidationTimeoutError) Is(err error) bool

Is checks that a given error is a ValidationTimeoutError.

func (*ValidationTimeoutError) Unwrap

func (v *ValidationTimeoutError) Unwrap() error
