Functions

func LabelsForSimpleApp

func LabelsForSimpleApp(name, version string) map[string]string

LabelsForSimpleApp returns a standard set of labels for resources managed by this operator.

func ReconcileDeployment

func ReconcileDeployment(ctx context.Context, c client.Client, scheme *runtime.Scheme, app *appsv1alpha1.SimpleApp, version string) error

ReconcileDeployment ensures the Deployment exists and matches the desired state declared in SimpleApp.Spec.Deployment.

func ReconcilePVC

func ReconcilePVC(ctx context.Context, c client.Client, scheme *runtime.Scheme, app *appsv1alpha1.SimpleApp, version string) error

ReconcilePVC ensures the PersistentVolumeClaim matches the desired state or is deleted when the spec is removed.

Most PVC spec fields are immutable after the claim is bound. The only mutable field is spec.resources.requests.storage, which supports volume expansion when the StorageClass has allowVolumeExpansion: true. On update, we synchronize the storage request along with labels and owner references.

func ReconcileService

func ReconcileService(ctx context.Context, c client.Client, scheme *runtime.Scheme, app *appsv1alpha1.SimpleApp, version string) error

ReconcileService ensures the Service matches the desired state or is deleted when the spec is removed.

Types

type InvalidSpecError

type InvalidSpecError struct {
	Field   string
	Message string
}

InvalidSpecError is a permanent error indicating that a field in SimpleAppSpec contains invalid JSON that cannot be deserialized into the expected Kubernetes type.

func (*InvalidSpecError) Error

func (e *InvalidSpecError) Error() string
