consul 模板 {{node}} 默认值没用？

Question

我的领事模板版本：

# ./consul-template -v

consul-template v0.18.0-rc2 (652183d)

我尝试使用下面的模板来测试节点：

{{with node}}{{.Node.Node}} ({{.Node.Address}}){{range .Services}}
  {{.Service}} {{.Port}} ({{.Tags | join ","}}){{end}}
{{end}}

我运行 shell:

./consul-template -log-level debug -once -consul-addr consul-agent:9500 -template "/home/data/consul/templates/test1.tmpl:/home/data/consul/results/test1"

但是之后test1就没有结果了。输出调试信息如下所示，shell 永远等待：

但是如果我像这样更改模板：

{{with node "8c163f72e7ac"}}{{.Node.Node}} ({{.Node.Address}}){{range .Services}}
  {{.Service}} {{.Port}} ({{.Tags | join ","}}){{end}}
{{end}}

效果很好！ 为什么我必须给出节点名称？ 在 consul-template 文档 https://github.com/hashicorp/consul-template#node 中，它说

When called without any arguments then the node for the current agent is returned.

有什么帮助吗？
