Types

type OSImageQuery

type OSImageQuery struct {
	// K8sVersionPrefix is a version prefix for matching Kubernetes versions.
	K8sVersionPrefix string

	// TKRSelector is a label selector that resolved TKRs must satisfy.
	TKRSelector labels.Selector

	// OSImageSelector is a label selector that resolved OSImages must satisfy.
	OSImageSelector labels.Selector
}

OSImageQuery sets constraints for resolution of OSImages for the control plane or a machine deployment of a cluster.

func (*OSImageQuery) String

func (q *OSImageQuery) String() string

type OSImageResult

type OSImageResult struct {
	// K8sVersion is the latest conforming K8s version. If empty, then no K8s version satisfied the query.
	K8sVersion string

	// TKRName is the latest conforming TKR name. If empty, then no TKRs satisfied the query.
	TKRName string

	// TKRsByK8sVersion maps resolved K8s versions to TKRs.
	TKRsByK8sVersion map[string]TKRs

	// OSImagesByTKR maps resolved TKR names to OSImages.
	OSImagesByTKR map[string]OSImages
}

OSImageResult carries the results of OSImage resolution for the control plane or a machine deployment of a cluster.

func (*OSImageResult) String

func (r *OSImageResult) String() string

type OSImages

type OSImages map[string]*runv1.OSImage

OSImages is a set of OSImage objects implemented as a map osImage.Name -> osImage.

func (OSImages) Filter

func (osImages OSImages) Filter(f func(osImage *runv1.OSImage) bool) OSImages

Filter returns a subset of OSImages satisfying the predicate f.

func (OSImages) String

func (osImages OSImages) String() string

type Query

type Query struct {
	// ControlPlane specifies the Query for the control plane.
	// Set to nil if we want to skip resolving the control plane part.
	ControlPlane *OSImageQuery

	// MachineDeployments specifies the OSImageQueries for worker machine deployments.
	// An individual machine deployment query part may be set to nil if we want to skip resolving it.
	MachineDeployments []*OSImageQuery
}

Query sets constraints for resolution of TKRs. Its structure reflects Cluster API cluster topology.

func (Query) String

func (q Query) String() string

type Result

type Result struct {
	// ControlPlane carries the Result for the  control plane.
	// It is set to nil if resolving the control plane part was skipped.
	ControlPlane *OSImageResult

	// ControlPlane carries the Result for worker machine deployments.
	// An individual machine deployment result is set to nil if resolving it was skipped.
	MachineDeployments []*OSImageResult
}

Result carries the results of TKR resolution. Its structure reflects Cluster API cluster topology.

func (Result) String

func (r Result) String() string

type TKRs

type TKRs map[string]*runv1.TanzuKubernetesRelease

TKRs is a set of TanzuKubernetesRelease objects implemented as a map tkr.Name -> tkr.

func (TKRs) Filter

func (tkrs TKRs) Filter(f func(tkr *runv1.TanzuKubernetesRelease) bool) TKRs

Filter returns a subset of TKRs satisfying the predicate f.

func (TKRs) Intersect

func (tkrs TKRs) Intersect(other TKRs) TKRs
