go-templates - 无法将 readFile 的输出转换为 List 进行迭代

Question

我正在使用helmfile进行 helm 发布。

我有一个 yaml 文件projects.yaml

# projects.yaml
- yako
- pera
- okta

在values.yaml.gotmpl中，我想遍历projects.yaml的内容：

# values.yaml.gotmpl
{{ $projects := readFile 'projects.yaml' }}
{{ range $_, $project := $projects }}
   # do something with $project . e.g: tpl (readFile 'proj-config.yaml') (dict $name $project)
{{ end}}

不幸的是，我收到了这个错误：

failed to render [values.yaml.gotmpl], because of template: stringTemplate:60:41:
 executing "stringTemplate" at <$projects>: range can't iterate over projects:
- yako
- pera
- okta

我做了很多盲目的尝试来让它发挥作用：

• {{ range $_, $project := $projects | fromYaml }}
• {{ range $_, $project := $projects | toYaml }}
• {{ range $_, $project := $projects | list }}

没门

Answer 1

{{ $projects := readFile "./projects.yaml"}}
{{ range $_, $project := get "projects" $projects }}
    {{ $project.attr1 }}
{{end}}
