Functions

func Apply

func Apply(
	o *Options,
	storage states.StateStorage,
	planResources *apiv1.Intent,
	changes *opsmodels.Changes,
	out io.Writer,
) error

The Apply function will apply the resources changes through the execution Kusion Engine, and will save the state to specified storage.

You can customize the runtime of engine and the state storage through `runtime` and `storage` parameters.

Example:

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

err = Apply(o, kubernetesRuntime, stateStorage, planResources, changes, os.Stdout)
if err != nil {
    return err
}

func NewCmdApply

func NewCmdApply() *cobra.Command

func Watch

func Watch(
	o *Options,
	planResources *apiv1.Intent,
	changes *opsmodels.Changes,
) error

Watch function will observe the changes of each resource by the execution engine.

Example:

o := NewApplyOptions()
kubernetesRuntime, err := runtime.NewKubernetesRuntime()
if err != nil {
    return err
}

Watch(o, kubernetesRuntime, planResources, changes, os.Stdout)
if err != nil {
    return err
}

Types

type Flag

type Flag struct {
	Yes    bool
	DryRun bool
	Watch  bool
}

type Options

type Options struct {
	previewcmd.Options
	Flag
}

Options defines flags for the `apply` command

NewApplyOptions returns a new ApplyOptions instance
