示例1: buildContainerListOptions

func buildContainerListOptions(opts *psOptions) (*types.ContainerListOptions, error) {
	options := &types.ContainerListOptions{
		All:     opts.all,
		Limit:   opts.last,
		Size:    opts.size,
		Filters: opts.filter.Value(),
	}

	if opts.nLatest && opts.last == -1 {
		options.Limit = 1
	}

	// Currently only used with Size, so we can determine if the user
	// put {{.Size}} in their format.
	pre := &preProcessor{opts: options}
	tmpl, err := templates.Parse(opts.format)

	if err != nil {
		return nil, err
	}

	// This shouldn't error out but swallowing the error makes it harder
	// to track down if preProcessor issues come up. Ref #24696
	if err := tmpl.Execute(ioutil.Discard, pre); err != nil {
		return nil, err
