Functions

func GetTopic

func GetTopic(e interface{}) string

GetTopic converts an event from an interface type to the specific event topic id

func NewPlatform

func NewPlatform() (stdio.Platform, error)

NewPlatform returns a linux platform for use with I/O operations

func ReadOptions

func ReadOptions(path string) (*options.Options, error)

ReadOptions reads the option information from the path. When the file does not exist, ReadOptions returns nil without an error.

func ReadRuntime

func ReadRuntime(path string) (string, error)

ReadRuntime reads the runtime information from the path

func ShouldKillAllOnExit

func ShouldKillAllOnExit(ctx context.Context, bundlePath string) bool

ShouldKillAllOnExit reads the bundle's OCI spec and returns true if there is an error reading the spec or if the container has a private PID namespace

func WriteOptions

func WriteOptions(path string, opts options.Options) error

WriteOptions writes the options information into the path

func WriteRuntime

func WriteRuntime(path, runtime string) error

WriteRuntime writes the runtime information into the path

Types

type Container

type Container struct {

	// ID of the container
	ID string
	// Bundle path
	Bundle string
	// contains filtered or unexported fields
}
