const NodePoolHashVersion = "v2"

We need to bump the NodePoolHashVersion when we make an update to the NodePool CRD under these conditions: 1. A field changes its default value for an existing field that is already hashed 2. A field is added to the hash calculation with an already-set value 3. A field is removed from the hash calculations

Types

type Budget added in v0.34.0

type Budget struct {
	// Nodes dictates the maximum number of NodeClaims owned by this NodePool
	// that can be terminating at once. This is calculated by counting nodes that
	// have a deletion timestamp set, or are actively being deleted by Karpenter.
	// This field is required when specifying a budget.
	// This cannot be of type intstr.IntOrString since kubebuilder doesn't support pattern
	// checking for int nodes for IntOrString nodes.
	// Ref: https://github.com/kubernetes-sigs/controller-tools/blob/55efe4be40394a288216dab63156b0a64fb82929/pkg/crd/markers/validation.go#L379-L388
	// +kubebuilder:validation:Pattern:="^((100|[0-9]{1,2})%|[0-9]+)$"
	// +kubebuilder:default:="10%"
	Nodes string `json:"nodes" hash:"ignore"`
	// Schedule specifies when a budget begins being active, following
	// the upstream cronjob syntax. If omitted, the budget is always active.
	// Timezones are not supported.
	// This field is required if Duration is set.
	// +kubebuilder:validation:Pattern:=`^(@(annually|yearly|monthly|weekly|daily|midnight|hourly))|((.+)\s(.+)\s(.+)\s(.+)\s(.+))$`
	// +optional
	Schedule *string `json:"schedule,omitempty" hash:"ignore"`
	// Duration determines how long a Budget is active since each Schedule hit.
	// Only minutes and hours are accepted, as cron does not work in seconds.
	// If omitted, the budget is always active.
	// This is required if Schedule is set.
	// This regex has an optional 0s at the end since the duration.String() always adds
	// a 0s at the end.
	// +kubebuilder:validation:Pattern=`^((([0-9]+(h|m))|([0-9]+h[0-9]+m))(0s)?)$`
	// +kubebuilder:validation:Type="string"
	// +optional
	Duration *metav1.Duration `json:"duration,omitempty" hash:"ignore"`
}

Budget defines when Karpenter will restrict the number of Node Claims that can be terminating simultaneously.

func (*Budget) DeepCopy added in v0.34.0

func (in *Budget) DeepCopy() *Budget

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Budget.

func (*Budget) DeepCopyInto added in v0.34.0

func (in *Budget) DeepCopyInto(out *Budget)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*Budget) GetAllowedDisruptions added in v0.34.0

func (in *Budget) GetAllowedDisruptions(c clock.Clock, numNodes int) (int, error)

GetAllowedDisruptions returns an intstr.IntOrString that can be used a comparison for calculating if a disruption action is allowed. It returns an error if the schedule is invalid. This returns MAXINT if the value is unbounded.

func (*Budget) IsActive added in v0.34.0

func (in *Budget) IsActive(c clock.Clock) (bool, error)

IsActive takes a clock as input and returns if a budget is active. It walks back in time the time.Duration associated with the schedule, and checks if the next time the schedule will hit is before the current time. If the last schedule hit is exactly the duration in the past, this means the schedule is active, as any more schedule hits in between would only extend this window. This ensures that any previous schedule hits for a schedule are considered.
