Overview

Package composite implements Crossplane composite resources.

Constants

View Source 
const (
	// FieldOwnerXR owns the fields this controller mutates on composite
	// resources (XR).
	FieldOwnerXR = "apiextensions.crossplane.io/composite"

	// FieldOwnerComposedPrefix owns the fields this controller mutates on composed
	// resources.
	FieldOwnerComposedPrefix = "apiextensions.crossplane.io/composed"
)

Server-side-apply field owners. We need two of these because it's possible an invocation of this controller will operate on the same resource in two different contexts. For example if an XR composes another XR we'll spin up two XR controllers. The 'parent' XR controller will treat the child XR as a composed resource, while the child XR controller will treat it as an XR. The controller owns different parts of the resource (i.e. has different fully specified intent) depending on the context.

Functions

func Apply added in v1.11.0 

func Apply(p v1.Patch, cp resource.Composite, cd resource.Composed, only ...v1.PatchType) error

Apply executes a patching operation between the from and to resources. Applies all patch types unless an 'only' filter is supplied.

func ApplyCombineFromVariablesPatch added in v1.11.0 

func ApplyCombineFromVariablesPatch(p v1.Patch, from, to runtime.Object) error

ApplyCombineFromVariablesPatch patches the "to" resource, taking a list of input variables and combining them into a single output value. The single output value may then be further transformed if they are defined on the patch.

func ApplyEnvironmentPatch added in v1.11.0 

func ApplyEnvironmentPatch(p v1.EnvironmentPatch, cp, env runtime.Object) error

ApplyEnvironmentPatch executes a patching operation between the cp and env objects.

func ApplyFromFieldPathPatch added in v1.11.0 

func ApplyFromFieldPathPatch(p v1.Patch, from, to runtime.Object) error

ApplyFromFieldPathPatch patches the "to" resource, using a source field on the "from" resource. Values may be transformed if any are defined on the patch.

func ApplyToObjects added in v1.11.0 

func ApplyToObjects(p v1.Patch, cp, cd runtime.Object, only ...v1.PatchType) error

ApplyToObjects works like c.Apply but accepts any kind of runtime.Object (such as EnvironmentConfigs). It might be vulnerable to conversion panics (see https://github.com/crossplane/crossplane/pull/3394 for details).

func AsState added in v1.14.0 

func AsState(xr resource.Composite, xc managed.ConnectionDetails, rs ComposedResourceStates) (*v1beta1.State, error)

func Combine(c v1.Combine, vars []any) (any, error)

Combine calls the appropriate combiner.

func CombineString added in v1.11.0 

func CombineString(format string, vars []any) (any, error)

CombineString returns a single output by running a string format with all of its input variables.

func ComposedFieldOwnerName added in v1.14.8 

func ComposedFieldOwnerName(xr *composite.Unstructured) string

ComposedFieldOwnerName generates a unique field owner name for a given Crossplane composite resource (XR). This uniqueness is crucial to prevent multiple XRs, which compose the same resource, from continuously alternating as controllers.

The function generates a deterministic hash based on the XR's name and GroupKind (GK), ensuring consistency even during system restores. The hash does not include the XR's UID (as it's not deterministic), namespace (XRs don't have one), or version (to allow version changes without needing to update the field owner name).

We decided to include the GK in the hash to prevent transferring ownership of composed resources across XRs with whole new GK, as that should not be supported without manual intervention.

Given that field owner names are limited to 128 characters, the function truncates the hash to 32 characters. A longer hash was deemed unnecessary.

EnqueueForCompositionRevisionFunc returns a function that enqueues (the related) XRs when a new CompositionRevision is created. This speeds up reconciliation of XRs on changes to the Composition by not having to wait for the 60s sync period, but be instant.
