本篇文章向大家介绍《文件未被正确导入 Helm》，主要包括，具有一定的参考价值，需要的朋友可以参考一下。
问题内容
我正在创建 helm chart，但在导入文件时遇到问题：
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 }}
这会导入文件 config/varnish/nginx.conf ，但是文件 config/varnish/default.vcl.tmpl 是使用 \n 而不是换行符导入的，因此 configmap 上的数据都会出现错误： p>
apiversion: v1

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。
正确答案
它们实际上与 yaml 的 pov 等效，只是不那么漂亮，但对于您的具体情况来说最重要的是，因为 yaml 无法在不引用它的情况下表示 尾随 空白，这就是它所做的，因为行164 的 .tmpl 文件，如 \n \n 所示：
\ }\n \n}\n\nsub 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 .
在编辑器中打开“去除尾随空格”会有所帮助，或者对于这种特定情况，您可以修复第 164 行
