helm中目录的嵌套范围

Question

必须根据树中某些文件的存在来生成模板。 我发现最好的方法是在 helm 文件中使用多个范围和一些 ifs 来检查，但它表明 helm 不喜欢这种嵌套。

图表树

├── ms-values
│   ├── shared
│   │   ├── ms1.yml
│   │   └── ms2.yml
│   └── devops
│       ├── test
│       │   └── ms3.yml
│       ├── ms3.yml
│       └── ms4.yml
├── family-values
│   ├── test
│   │   └── shared.yml
│   ├── devops.yml
│   └── shared.yml
├── global-values
│   ├── test.yml
│   └── dev.yml
├── templates
│   └── micoservices.yml
└── values.yml

我在模板中有一个文件 microservices.yml，内容如下：

  {{ $enviroment := trimSuffix ".yml" (base $globalPath) }}
    enviroment: {{ $enviroment }}
    {{- range $familyPath, $familyBytes := $.Files.Glob "family-values/*.yml" -}}
    {{ $family := trimSuffix ".yml" (base $familyPath) }}
    {{- $familyMsPath := print "ms-values/" $family "/*.yml" }}
      {{- range $microservicePath, $microserviceBytes := $.Files.Glob $familyMsPath -}}
        {{- $microservice := trimSuffix ".yml" (base $microservicePath) -}}
        {{- $microserviceExt := base $microservicePath -}}
        {{- $envMSPath := print "ms-values/" $family "/" $enviroment "/" $microserviceExt -}}
        {{- $microserviceEnv := $.Files.Glob $envMSPath }}
    familys: {{ $family }}
    enviroment: {{ $enviroment }}
    MS: {{ $microservice -}} 
        {{- if $microserviceEnv }}
    MS_PATCH: {{- $envMSPath -}}
        {{- end -}}
        {{- $FamilyENVPath := print  "family-values/" $enviroment "/" $family ".yml" -}}
        {{- $FamilyENV := $.Files.Glob $FamilyENVPath }}
        {{- if $FamilyENV }}
    familyENVpatch: {{ $FamilyENVPath }}
        {{ end }}
    {{ end }}  
  {{ end }}
{{ end }}

运行helm template . --debug i我已经渲染了图表，但也出现了这个错误：

helm.go:81: [debug] error converting YAML to JSON: yaml: line 2: mapping values are not allowed in this context

Any ideas??

helm 文件缩进的问题（我认为）。我这里解决的是代码

{{- $enviroment := trimSuffix ".yml" (base $globalPath) }}
{{ range $familyPath, $familyBytes := $.Files.Glob "family-values/*.yml" }}
{{ $family := trimSuffix ".yml" (base $familyPath) -}}
{{ $familyMsPath := print "ms-values/" $family "/*.yml" }}
{{ range $microservicePath, $microserviceBytes := $.Files.Glob $familyMsPath }}
{{ $microservice := trimSuffix ".yml" (base $microservicePath) -}}
{{ $envMSPath := print "ms-values/" $family "/" $enviroment "/" $microservice ".yml" }}
{{ $microserviceEnv := $.Files.Glob $envMSPath }}
{{ $microserviceData := $.Files.Get $microservicePath | fromYaml}}
{{ if has $enviroment $microserviceData.enviromentEnabled }}
