Functions

func ComputeAppRevisionHash

func ComputeAppRevisionHash(appRevision *v1beta1.ApplicationRevision) (string, error)

ComputeAppRevisionHash computes a single hash value for an appRevision object Spec of Application/WorkloadDefinitions/ComponentDefinitions/TraitDefinitions/ScopeDefinitions will be taken into compute

func ComputeComponentRevisionHash

func ComputeComponentRevisionHash(comp *types.ComponentManifest) (string, error)

ComputeComponentRevisionHash to compute component hash

func DeepEqualRevision

func DeepEqualRevision(old, new *v1beta1.ApplicationRevision) bool

DeepEqualRevision will compare the spec of Application and Definition to see if the Application is the same revision Spec of AC and Component will not be compared as they are generated by the application and definitions Note the Spec compare can only work when the RawExtension are decoded well in the RawExtension.Object instead of in RawExtension.Raw(bytes)

func Setup

func Setup(mgr ctrl.Manager, args core.Args) error

Setup adds a controller that reconciles AppRollout.

func SprintComponentManifest

func SprintComponentManifest(cm *types.ComponentManifest) string

SprintComponentManifest formats and returns the resulting string.

Types

type AppHandler

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

AppHandler handles application reconcile

func NewAppHandler

func NewAppHandler(ctx context.Context, r *Reconciler, app *v1beta1.Application, parser *appfile.Parser) (*AppHandler, error)

NewAppHandler create new app handler

func (*AppHandler) Delete

func (h *AppHandler) Delete(ctx context.Context, cluster string, owner common.ResourceCreatorRole, manifest *unstructured.Unstructured) error

Delete delete manifests from k8s.

func (*AppHandler) Dispatch

func (h *AppHandler) Dispatch(ctx context.Context, cluster string, owner common.ResourceCreatorRole, manifests ...*unstructured.Unstructured) error

Dispatch apply manifests into k8s.

func (*AppHandler) FinalizeAndApplyAppRevision

func (h *AppHandler) FinalizeAndApplyAppRevision(ctx context.Context) error

FinalizeAndApplyAppRevision finalise AppRevision object and apply it

func (*AppHandler) GenerateApplicationSteps

func (h *AppHandler) GenerateApplicationSteps(ctx context.Context,
	app *v1beta1.Application,
	appParser *appfile.Parser,
	af *appfile.Appfile,
	appRev *v1beta1.ApplicationRevision) ([]wfTypes.TaskRunner, error)

GenerateApplicationSteps generate application steps. nolint:gocyclo

func (*AppHandler) HandleComponentsRevision

func (h *AppHandler) HandleComponentsRevision(ctx context.Context, compManifests []*types.ComponentManifest) error

HandleComponentsRevision manages Component revisions 1. if update component create a new component Revision 2. check all componentTrait rely on componentRevName, if yes fill it

func (*AppHandler) PrepareCurrentAppRevision

func (h *AppHandler) PrepareCurrentAppRevision(ctx context.Context, af *appfile.Appfile) error

PrepareCurrentAppRevision will generate a pure revision without metadata and rendered result the generated revision will be compare with the last revision to see if there's any difference.

func (*AppHandler) ProduceArtifacts

func (h *AppHandler) ProduceArtifacts(ctx context.Context, comps []*types.ComponentManifest, policies []*unstructured.Unstructured) error

ProduceArtifacts will produce Application artifacts that will be saved in configMap.

func (*AppHandler) UpdateAppLatestRevisionStatus

func (h *AppHandler) UpdateAppLatestRevisionStatus(ctx context.Context) error

UpdateAppLatestRevisionStatus only call to update app's latest revision status after applying manifests successfully otherwise it will override previous revision which is used during applying to do GC jobs

type Reconciler

type Reconciler struct {
	client.Client

	Scheme   *runtime.Scheme
	Recorder event.Recorder
	// contains filtered or unexported fields
}
