Interface Execer

xunix/exec.go:37–44

The code henceforth is copied straight and modified slightly from "k8s.io/utils/exec". Their interface doesn't allow for a reference to exec.Cmd.Process which we use to kill and wait for a process to exit.

// exec.Cmd.Process which we use to kill and wait for a process to exit.

type Execer interface {
	// CommandContext returns a Cmd instance which can be used to run a single command.
	//
	// The provided context is used to kill the process if the context becomes done
	// before the command completes on its own. For example, a timeout can be set in
	// the context.
	CommandContext(ctx context.Context, cmd string, args ...string) Cmd
}

type Cmd interface {
	utilexec.Cmd
