Functions

func NewCmdPreview

func NewCmdPreview() *cobra.Command

func Preview

func Preview(
	o *Options,
	storage states.StateStorage,
	planResources *models.Spec,
	project *projectstack.Project,
	stack *projectstack.Stack,
) (*opsmodels.Changes, error)

The Preview function calculates the upcoming actions of each resource through the execution Kusion Engine, and you can customize the runtime of engine and the state storage through `runtime` and `storage` parameters.

Example:

o := NewPreviewOptions()
stateStorage := &states.FileSystemState{
    Path: filepath.Join(o.WorkDir, states.KusionState)
}
kubernetesRuntime, err := runtime.NewKubernetesRuntime()
if err != nil {
    return err
}

changes, err := Preview(o, kubernetesRuntime, stateStorage,
    planResources, project, stack, os.Stdout)
if err != nil {
    return err
}
