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}}
我运行外壳：
./consul-template -log-level debug -once -consul-addr consul-agent:9500 -template "/home/data/consul/templates/test1.tmpl:/home/data/consul/results/test1"
但在那之后，test1 没有结果。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}}
它工作正常！为什么我必须给出节点名称？在领事模板文档https://github.com/hashicorp/consul-template#node中，它说
当不带任何参数调用时，将返回当前代理的节点。
有什么帮助吗？
