Types

type ApplyFlags 

type ApplyFlags struct {
	RecordFlags *genericclioptions.RecordFlags
	PrintFlags  *genericclioptions.PrintFlags

	DeleteFlags *delete.DeleteFlags

	FieldManager   string
	Selector       string
	Prune          bool
	PruneResources []prune.Resource
	ApplySetRef    string
	All            bool
	Overwrite      bool
	OpenAPIPatch   bool

	// DEPRECATED: Use PruneAllowlist instead
	PruneWhitelist []string // TODO: Remove this in kubectl 1.28 or later
	PruneAllowlist []string

	genericiooptions.IOStreams
}

ApplyFlags directly reflect the information that CLI is gathering via flags. They will be converted to Options, which reflect the runtime requirements for the command. This structure reduces the transformation to wiring and makes the logic itself easy to unit test

func NewApplyFlags 

func NewApplyFlags(streams genericiooptions.IOStreams) *ApplyFlags

NewApplyFlags returns a default ApplyFlags

func (*ApplyFlags) AddFlags 

func (flags *ApplyFlags) AddFlags(cmd *cobra.Command)

AddFlags registers flags for a cli

func (*ApplyFlags) ToOptions 

func (flags *ApplyFlags) ToOptions(f cmdutil.Factory, cmd *cobra.Command, baseName string, args []string) (*ApplyOptions, error)

ToOptions converts from CLI inputs to runtime inputs

type ApplyOptions 

type ApplyOptions struct {
	Recorder genericclioptions.Recorder

	PrintFlags *genericclioptions.PrintFlags
	ToPrinter  func(string) (printers.ResourcePrinter, error)

	DeleteOptions *delete.DeleteOptions

	ServerSideApply bool
	ForceConflicts  bool
	FieldManager    string
	Selector        string
	DryRunStrategy  cmdutil.DryRunStrategy
	Prune           bool
	PruneResources  []prune.Resource

	All          bool
	Overwrite    bool
	OpenAPIPatch bool

	ValidationDirective string
	Validator           validation.Schema
	Builder             *resource.Builder
	Mapper              meta.RESTMapper
	DynamicClient       dynamic.Interface
	OpenAPISchema       openapi.Resources

	Namespace        string
	EnforceNamespace bool

	genericiooptions.IOStreams

	// Stores visited objects/namespaces for later use
	// calculating the set of objects to prune.
	VisitedUids       sets.Set[types.UID]
	VisitedNamespaces sets.Set[string]

	// Function run after the objects are generated and
	// stored in the "objects" field, but before the
	// apply is run on these objects.
	PreProcessorFn func() error
	// Function run after all objects have been applied.
	// The standard PostProcessorFn is "PrintAndPrunePostProcessor()".
	PostProcessorFn func() error

	// ApplySet tracks the set of objects that have been applied, for the purposes of pruning.
	// See git.k8s.io/enhancements/keps/sig-cli/3659-kubectl-apply-prune
	ApplySet *ApplySet
	// contains filtered or unexported fields
}

ApplyOptions defines flags and other configuration parameters for the `apply` command

func (*ApplyOptions) GetObjects 

func (o *ApplyOptions) GetObjects() ([]*resource.Info, error)

GetObjects returns a (possibly cached) version of all the valid objects to apply as a slice of pointer to resource.Info and an error if one or more occurred. IMPORTANT: This function can return both valid objects AND an error, since "ContinueOnError" is set on the builder. This function should not be called until AFTER the "complete" and "validate" methods have been called to ensure that the ApplyOptions is filled in and valid.

func (*ApplyOptions) MarkNamespaceVisited 

func (o *ApplyOptions) MarkNamespaceVisited(info *resource.Info)

MarkNamespaceVisited keeps track of which namespaces the applied objects belong to. Used for pruning.

func (*ApplyOptions) MarkObjectVisited 

func (o *ApplyOptions) MarkObjectVisited(info *resource.Info) error

MarkObjectVisited keeps track of UIDs of the applied objects. Used for pruning.

func (*ApplyOptions) PrintAndPrunePostProcessor 

func (o *ApplyOptions) PrintAndPrunePostProcessor() func() error

PrintAndPrunePostProcessor returns a function which meets the PostProcessorFn function signature. This returned function prints all the objects as a list (if configured for that), and prunes the objects not applied. The returned function is the standard apply post processor.

func (*ApplyOptions) Run 

func (o *ApplyOptions) Run() error

Run executes the `apply` command.

func (*ApplyOptions) Validate 

func (o *ApplyOptions) Validate() error

Validate verifies if ApplyOptions are valid and without conflicts.

type ApplySet 

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

ApplySet tracks the information about an applyset apply/prune

func (*ApplySet) AllPrunableResources 

func (a *ApplySet) AllPrunableResources() []*meta.RESTMapping

AllPrunableResources returns the list of all resources that should be considered for pruning. This is potentially a superset of the resources types that actually contain resources.

func (*ApplySet) BeforeApply 

func (a *ApplySet) BeforeApply(objects []*resource.Info, dryRunStrategy cmdutil.DryRunStrategy, validationDirective string) error

BeforeApply should be called before applying the objects. It pre-updates the parent object so that it covers the resources that will be applied. In this way, even if we are interrupted, we will not leak objects.

func (ApplySet) FieldManager 

func (a ApplySet) FieldManager() string

func (*ApplySet) FindAllObjectsToPrune 

func (a *ApplySet) FindAllObjectsToPrune(ctx context.Context, dynamicClient dynamic.Interface, visitedUids sets.Set[types.UID]) ([]PruneObject, error)
