Types

type ApplicationInstaller

type ApplicationInstaller interface {
	// GetAppCache return the application cache location (i.e. where source and others temporary files are written)
	GetAppCache() string

	// DonwloadSource the application's source into downloadDest and returns the full path to the sources.
	DonwloadSource(ctx context.Context, log *zap.SugaredLogger, seedClient ctrlruntimeclient.Client, applicationInstallation *appskubermaticv1.ApplicationInstallation, downloadDest string) (string, error)

	// Apply function installs the application on the user-cluster and returns an error if the installation has failed. StatusUpdater is guaranteed to be non nil. This is idempotent.
	Apply(ctx context.Context, log *zap.SugaredLogger, seedClient ctrlruntimeclient.Client, userClient ctrlruntimeclient.Client, applicationInstallation *appskubermaticv1.ApplicationInstallation, appSourcePath string) (util.StatusUpdater, error)

	// Delete function uninstalls the application on the user-cluster and returns an error if the uninstallation has failed. StatusUpdater is guaranteed to be non nil. This is idempotent.
	Delete(ctx context.Context, log *zap.SugaredLogger, seedClient ctrlruntimeclient.Client, userClient ctrlruntimeclient.Client, applicationInstallation *appskubermaticv1.ApplicationInstallation) (util.StatusUpdater, error)
}

ApplicationInstaller handles the installation / uninstallation of an Application on the user cluster.

type ApplicationManager

type ApplicationManager struct {
	// ApplicationCache is the path to the directory used for caching applications. (i.e. location where application's source will be downloaded, Helm repository cache ...)
	ApplicationCache string

	// Kubeconfig of the user-cluster
	Kubeconfig string

	// Namespace where credentials secrets are stored.
	SecretNamespace string
}

ApplicationManager handles the installation / uninstallation of an Application on the user-cluster.

func (*ApplicationManager) Apply

func (a *ApplicationManager) Apply(ctx context.Context, log *zap.SugaredLogger, seedClient ctrlruntimeclient.Client, userClient ctrlruntimeclient.Client, applicationInstallation *appskubermaticv1.ApplicationInstallation, appSourcePath string) (util.StatusUpdater, error)

Apply creates the namespace where the application will be installed (if necessary) and installs the application.

func (*ApplicationManager) Delete

func (a *ApplicationManager) Delete(ctx context.Context, log *zap.SugaredLogger, seedClient ctrlruntimeclient.Client, userClient ctrlruntimeclient.Client, applicationInstallation *appskubermaticv1.ApplicationInstallation) (util.StatusUpdater, error)

Delete uninstalls the application where the application was installed if necessary.

func (*ApplicationManager) DonwloadSource

func (a *ApplicationManager) DonwloadSource(ctx context.Context, log *zap.SugaredLogger, seedClient ctrlruntimeclient.Client, applicationInstallation *appskubermaticv1.ApplicationInstallation, downloadDest string) (string, error)

DonwloadSource the application's source using the appropriate provider into downloadDest and returns the full path to the sources.

func (*ApplicationManager) GetAppCache

func (a *ApplicationManager) GetAppCache() string
