Types

type AppStateManager

type AppStateManager interface {
	CompareAppState(app *v1alpha1.Application, project *v1alpha1.AppProject, revisions []string, sources []v1alpha1.ApplicationSource, noCache bool, noRevisionCache bool, localObjects []string, hasMultipleSources bool) (*comparisonResult, error)

	statusRefreshTimeout time.Duration,
	resourceTracking argo.ResourceTracking,
	persistResourceHealth bool,
	repoErrorGracePeriod time.Duration,
	serverSideDiff bool,
) AppStateManager

NewAppStateManager creates new instance of AppStateManager

type ApplicationController

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

ApplicationController is the controller for application resources.
