gomplate:在<.Values.tpl.organization>：map上执行"<arg>“时没有关键字"Values”的条目

Question

这是我的yaml文件

apiVersion: myapi.com/v1
kind: Template
metadata:
  name: {{ .Values.tpl.organization }}-template-mkytemplatetemplate
spec:
  # Add fields here
  organization: {{ .Values.tpl.organization }}
  purpose: {{ .Values.tpl.purpose }}
  version: {{ .Chart.appVersion }}
  location: {{.Values.location}}/template.tgz
  name: mkytemplatetemplate
  namePattern: ^[a-z0-9\-]{3,25}$
  description: "# Please do not use the template\ntest modify run.sh"
  author: string

我使用gomplate将所有{{xxx}}替换为Chart.yaml或Values.yaml中的相应值。以下是我的代码

func main() {
    log.Println("hello")
    //BasicTemplate()
    Gomplate()
}

func Gomplate() {
    workspace := "/Users/i517131/code/mkytemplatetemplate/.ci/chart"
    inBs, _ := ioutil.ReadFile(path.Join(workspace, "templates/template.yaml"))
    in := string(inBs)
    cfg := &gomplate.Config{
        Input: in,
        OutputFiles: []string{path.Join(workspace, "result.yaml")},
        DataSources: []string{
            fmt.Sprintf("%s=%s", "Chart", path.Join(workspace, "Chart.yaml")),
            fmt.Sprintf("%s=%s", "Values", path.Join(workspace, "values.yaml")),
        },
    }
    err := gomplate.RunTemplates(cfg)
    if err != nil {
        panic(err)
    }
}

但是我收到一个类似于此panic: template: <arg>:4:18: executing "<arg>" at <.Values.tpl.organization>: map has no entry for key "Values"的错误。在err := gomplate.RunTemplates(cfg)

首先，当我运行cmd gomplate -f .ci/chart/templates/template.yaml -d Chart=.ci/chart/Chart.yaml -d Values=.ci/chart/values.yaml -o result.yaml时，我收到保存错误。我在网上搜索，在github上，作者建议我们使用-c而不是-d

但是go中的模板只能使用gomplate.Config来运行模板，不支持-c。我能做什么?

-c命令生成的结果

apiVersion: myapi.com/v1
kind: Template
metadata:
  name: mky-template-mkytemplatetemplate
spec:
  # Add fields here
  organization: mky
  purpose: prod
  version: 1.0.0
  location: _/template.tgz
  name: mkytemplatetemplate
  namePattern: ^[a-z0-9\-]{3,25}$

使用Contexts而不是DataSource

cfg := &gomplate.Config{
        Input: in,
        OutputFiles: []string{path.Join(workspace, "result.yaml")},
        Contexts: []string{
            fmt.Sprintf("%s=%s", "Chart", path.Join(workspace, "Chart.yaml")),
            fmt.Sprintf("%s=%s", "Values", path.Join(workspace, "values.yaml")),
        },
    }
