Constants

const (
	// GenericExitCodeKilled indicates the container runtime killed the process.
	GenericExitCodeKilled = 137

	// GenericExitCodeCannotExec indicates the command cannot be executed.
	// In a shell, this generally is a form of permission issues (i.e. the
	// binary was found but is not +x). However, container runtimes also
	// use this to indicate that the binary wasn't found at all, which is
	// extremely common when we try to use common tools such as `tar` but
	// the image is missing them.
	GenericExitCodeCannotExec = 126

	GenericExitCodeNotFound = 127
)

const TarExitCodePermissionDenied = 2

TarExitCodePermissionDenied is returned by `tar` if it does not have sufficient permissions to write the extracted files.
