You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: native.go
    path of file: ./repos/nanobox/util/provider
    
    the code of the file until where you have to start completion: package provider

import (
	"fmt"
	"net"
	"os"
	"os/exec"
	"path/filepath"
	"runtime"
	"strings"

	"github.com/jcelliott/lumber"

	"github.com/nanobox-io/nanobox/models"
	"github.com/nanobox-io/nanobox/util/config"
	"github.com/nanobox-io/nanobox/util/display"
)


    
func (native Native) Implode() error {
	// remove any crufty containers
	cmd := exec.Command("docker", "ps", "-a")
	bytes, err := cmd.CombinedOutput()
	if err != nil {
		return err
	}

	s := string(bytes)
	parts := strings.Split(s, "\n")
	containers := []string{}

	for _, part := range parts {
		if strings.Contains(part, "nanobox_") {
			containers = append(containers, strings.Fields(part)[0])
		}
	}

	if len(containers) == 0 {
		return nil
	}
	cmdParts := append([]string{"rm", "-f"}, containers...)
	cmd = exec.Command("docker", cmdParts...)
	cmd.Stdout = display.NewStreamer("  ")
	cmd.Stderr = display.NewStreamer("  ")

	return cmd.Run()
