我正在创建一个Helm Chart，我在导入文件时遇到了问题:
apiVersion: v1
kind: ConfigMap
metadata:
name: vcl-template
namespace: {{.Release.Namespace}}
data:
{{- (.Files.Glob "config/varnish/default.vcl.tmpl").AsConfig | nindent 2 }}
{{- (.Files.Glob "config/varnish/nginx.conf").AsConfig | nindent 2 }}
导入文件config/varnish/nginx.conf很好，但文件config/varnish/default.vcl.tmpl是用n而不是换行符导入的，所以ConfigMap上的数据都有问题:
apiVersion: v1
kind: ConfigMap
metadata:
name: vcl-template

为什么第二个文件没有正确导入?最新的Helm版本和最新的Go版本
有人有什么想法吗?这两个文件在VSCode上的编码显示为UTF8.
它们实际上与YAML的PoV是等价的，只是不那么漂亮，但对于您的特定情况最重要的是，这是因为YAML不能表示尾随空格而不引用它，这是由于.tmpl文件的第164行所做的，如:
中的n n所示 }n n}nnsub process_graphql_headers {n if (req.http.Store) {n hash_data(req.http.Store);n
$ sed -ne 164p default.vcl.tmpl | xxd
00000000: 2020 2020 0a .
打开"条带尾随空格"在你的编辑器中会有帮助，或者对于这种特殊情况，你可以修改第164行
