Functions

func ClientFromContext

func ClientFromContext(ctx context.Context) (cluster.Client, error)

Retrieve client from given context.

func MergeMaps

func MergeMaps(x, y map[string]any) map[string]any

Deep-merge two maps with the usual logic and return the result. The first map (x) must be deeply JSON (i.e. consist deeply of JSON values only). The maps given as input will not be changed.

func NewContextWithClient

func NewContextWithClient(ctx context.Context, client cluster.Client) context.Context

Create new context with client added as value.

func NewContextWithReconcilerName

func NewContextWithReconcilerName(ctx context.Context, reconcilerName string) context.Context

Create new context with reconciler name added as value.

func ReconcilerNameFromContext

func ReconcilerNameFromContext(ctx context.Context) (string, error)

Retrieve reconciler name from given context.

Types

type DummyGenerator

type DummyGenerator struct{}

DummyGenerator is a generator that does nothing.

func NewDummyGenerator

func NewDummyGenerator() (*DummyGenerator, error)

Create a new DummyGenerator.

func (*DummyGenerator) Generate

func (g *DummyGenerator) Generate(ctx context.Context, namespace string, name string, parameters types.Unstructurable) ([]client.Object, error)

Generate resource descriptors.

type Generator

type Generator interface {
	Generate(ctx context.Context, namespace string, name string, parameters types.Unstructurable) ([]client.Object, error)
}

Resource generator interface. When called from the reconciler, the arguments namespace, name and parameters will match the return values of the component's GetDeploymentNamespace(), GetDeploymentName() and GetSpec() methods, respectively.

type HelmGenerator

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

HelmGenerator is a Generator implementation that basically renders a given Helm chart. A few restrictions apply to the provided Helm chart: it must not contain any subcharts, some template functions are not supported, some bultin variables are not supported, and hooks are processed in a slightly different fashion.

func NewHelmGenerator

func NewHelmGenerator(name string, fsys fs.FS, chartPath string, client client.Client, discoveryClient discovery.DiscoveryInterface) (*HelmGenerator, error)

Create a new HelmGenerator. Deprecation warning: the parameters name, client and discoveryClient are ignored (can be passed as empty resp. nil) and will be removed in a future release; the according values will be retrieved from the context passed to Generate().

func (*HelmGenerator) Generate

func (g *HelmGenerator) Generate(ctx context.Context, namespace string, name string, parameters types.Unstructurable) ([]client.Object, error)

Generate resource descriptors.

type KustomizeGenerator

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

KustomizeGenerator is a Generator implementation that basically renders a given Kustomization.

func NewKustomizeGenerator

func NewKustomizeGenerator(fsys fs.FS, kustomizationPath string, templateSuffix string, client client.Client) (*KustomizeGenerator, error)

Create a new KustomizeGenerator. Deprecation warning: the parameter client is ignored (can be passed as nil) and will be removed in a future release; the according value will be retrieved from the context passed to Generate().

func (*KustomizeGenerator) Generate

func (g *KustomizeGenerator) Generate(ctx context.Context, namespace string, name string, parameters types.Unstructurable) ([]client.Object, error)

Generate resource descriptors.

type ObjectTransformer

type ObjectTransformer interface {
	TransformObjects(namespace string, name string, objects []client.Object) ([]client.Object, error)
}

Object transformer interface. Allows to manipulate the parameters returned by an existing generator.

type ParameterTransformer

type ParameterTransformer interface {
	TransformParameters(namespace string, name string, parameters types.Unstructurable) (types.Unstructurable, error)
}

Parameter transformer interface. Allows to manipulate the parameters passed to an existing generator.

type SchemeBuilder

type SchemeBuilder interface {
	AddToScheme(scheme *runtime.Scheme) error
}

SchemeBuilder interface.

type TemplateParameterTransformer

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

func NewTemplateParameterTransformer

func NewTemplateParameterTransformer(fsys fs.FS, path string) (*TemplateParameterTransformer, error)

func (*TemplateParameterTransformer) TransformParameters

func (t *TemplateParameterTransformer) TransformParameters(namespace string, name string, parameters types.Unstructurable) (types.Unstructurable, error)

type TransformableGenerator

type TransformableGenerator interface {
	Generator
	WithParameterTransformer(transformer ParameterTransformer) TransformableGenerator
	WithObjectTransformer(transformer ObjectTransformer) TransformableGenerator
}

Interface for generators that can be enhanced with parameter/object transformers.

func NewGenerator

func NewGenerator(generator Generator) TransformableGenerator

func NewHelmGeneratorWithObjectTransformer

func NewHelmGeneratorWithObjectTransformer(name string, fsys fs.FS, chartPath string, client client.Client, discoveryClient discovery.DiscoveryInterface, transformer ObjectTransformer) (TransformableGenerator, error)

Create a new HelmGenerator with an ObjectTransformer attached (further transformers can be attached to the returned generator object). Deprecation warning: the parameters name, client and discoveryClient are ignored (can be passed as empty resp. nil) and will be removed in a future release.

func NewHelmGeneratorWithParameterTransformer

func NewHelmGeneratorWithParameterTransformer(name string, fsys fs.FS, chartPath string, client client.Client, discoveryClient discovery.DiscoveryInterface, transformer ParameterTransformer) (TransformableGenerator, error)

Create a new HelmGenerator with a ParameterTransformer attached (further transformers can be attached to the returned generator object). Deprecation warning: the parameters name, client and discoveryClient are ignored (can be passed as empty resp. nil) and will be removed in a future release.

func NewKustomizeGeneratorWithObjectTransformer

func NewKustomizeGeneratorWithObjectTransformer(fsys fs.FS, kustomizationPath string, templateSuffix string, client client.Client, transformer ObjectTransformer) (TransformableGenerator, error)

Create a new KustomizeGenerator with an ObjectTransformer attached (further transformers can be attached to the returned generator object). Deprecation warning: the parameter client is ignored (can be passed as nil) and will be removed in a future release.

func NewKustomizeGeneratorWithParameterTransformer
