如何避免翻译一些舵图的`{{`？

Question

我想把下面的CRD放到舵图中，但它包含了go raw模板。如何让helm在rawTemplate中不翻译{{和}}。感谢您的回复。https://github.com/kubeflow/katib/blob/master/examples/random-example.yaml

              command:
              - "python"
              - "/mxnet/example/image-classification/train_mnist.py"
              - "--batch-size=64"
              {{- with .HyperParameters}}
              {{- range .}}
              - "{{.Name}}={{.Value}}"
              {{- end}}
              {{- end}}
            restartPolicy: Never

在Go模板语言中，表达式

{{ "{{" }}

将扩展为两个左花括号，用于需要使用Go模板语法生成Go模板语法的文档的情况；例如

{{ "{{" }}- if .Values.foo }}
- name: FOO
  value: {{ "{{" }} .Values.foo }}
{{ "{{" }}- end }}

(在Kubernetes Helm上下文中，您将使用此语法生成YAML，请特别注意如何处理空格；请考虑使用helm template来转储生成的内容。)
