func NewJsonnetCmd() *cobra.Command

Types

type DefaultProvider

type DefaultProvider struct {
	Subcommand string
	Pool       Pool
}

DefaultProvider provides a secure VM by calling the currently running the current binary with the provided subcommand.

func (*DefaultProvider) JsonnetVM

func (p *DefaultProvider) JsonnetVM(ctx context.Context) (VM, error)

type ErrorImporter

type ErrorImporter struct{}

ErrorImporter errors when calling "import".

func (*ErrorImporter) Import

func (importer *ErrorImporter) Import(importedFrom, importedPath string) (contents jsonnet.Contents, foundAt string, err error)

Import fetches data from a map entry. All paths are treated as absolute keys.

type Option

type Option func(o *vmOptions)

func WithJsonnetBinary

func WithJsonnetBinary(jsonnetBinaryPath string) Option

func WithProcessArgs

type VMProvider

type VMProvider interface {
	// JsonnetVM creates a new secure process-isolated Jsonnet VM whose
	// execution is bound to the provided context, i.e.,
	// cancelling the context will terminate the VM process.
	JsonnetVM(context.Context) (VM, error)
