Functions

func GetReadyCondition

func GetReadyCondition(status *corev1.NodeStatus) *corev1.NodeCondition

GetReadyCondition extracts the ready condition from the given status and returns that. Returns nil and -1 if the condition is not present, and the index of the located condition.

func IsNodeAvailable

func IsNodeAvailable(node *corev1.Node, minReadySeconds int32, now metav1.Time) bool

IsNodeAvailable returns true if the node is ready and minReadySeconds have elapsed or is 0. False otherwise.

func IsNodeReady

func IsNodeReady(node *corev1.Node) bool

IsNodeReady returns true if a node is ready; false otherwise.

func IsNodeUnreachable added in v0.3.0

func IsNodeUnreachable(node *corev1.Node) bool

IsNodeUnreachable returns true if a node is unreachable. Node is considered unreachable when its ready status is "Unknown".

Types

type ProviderID

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

func NewProviderID

func NewProviderID(id string) (*ProviderID, error)

NewProviderID parses the input string and returns a new ProviderID.

func (*ProviderID) CloudProvider

func (p *ProviderID) CloudProvider() string

CloudProvider returns the cloud provider portion of the ProviderID.

func (*ProviderID) Equals

func (p *ProviderID) Equals(o *ProviderID) bool

Equals returns true if both the CloudProvider and ID match.

func (*ProviderID) ID

func (p *ProviderID) ID() string

ID returns the identifier portion of the ProviderID.

func (*ProviderID) IndexKey added in v0.4.1

func (p *ProviderID) IndexKey() string

IndexKey returns a string concatenating the cloudProvider and the ID parts of the providerID. E.g Format: cloudProvider://optional/segments/etc/id. IndexKey: cloudProvider/id This is useful to use the providerID as a reliable index between nodes and machines as it guarantees the infra Providers contract.

func (*ProviderID) String

func (p *ProviderID) String() string

func (*ProviderID) Validate

func (p *ProviderID) Validate() bool
