Functions

func ApplyOverlay

func ApplyOverlay(current, overlay runtime.Object) error

Types

type Application

type Application struct {
	client.Client
	CR       client.Object
	FileRepo Repo
	GVK      schema.GroupVersionKind
	TmplFunc template.FuncMap
	Recorder record.EventRecorder
}

Application contains the resource of one single component which is applied to api server

func (*Application) Apply

func (a *Application) Apply(ctx context.Context, manifest string, log logr.Logger, needCompose bool) (bool, error)

Apply a template represents a component to api server

func (*Application) ApplyAll

func (a *Application) ApplyAll(ctx context.Context, manifestFiles []string, log logr.Logger) error

ApplyAll manifests dependent a single CR

func (*Application) ApplyFromObject

func (a *Application) ApplyFromObject(ctx context.Context, obj runtime.Object, log logr.Logger, needCompose bool) (bool, error)

ApplyFromObject apply an object to api server

type ErrorCollector

type ErrorCollector []error

func (*ErrorCollector) Collect

func (c *ErrorCollector) Collect(e error)

func (*ErrorCollector) Error

func (c *ErrorCollector) Error() error

type Repo

type Repo interface {
	ReadFile(path string) ([]byte, error)
	GetFilesRecursive(path string) ([]string, error)
}

Repo provides tools to access templates
