我有一个模板，可以使用以下命令渲染多次range迭代，我可以访问变量外部变量，例如$.Release.Name没有问题。但是，当我包含模板时，我无法让它工作：
{{ range $key, $val := $.Values.resources }}
...
annotations:
checksum/config: {{ include (print $.Template.BasePath "/secrets.yaml") . | sha256sum }}
{{ end }}
And in secrets.yaml:
apiVersion: "v1"
kind: "Secret"
metadata:
name: {{ $.Release.Name }}-secrets
我收到这个错误：
Error: render error in "botfront-project/templates/deployment.yaml": template: [filename] :19:28: executing [filename] at <include (print $.Template.BasePath "/secrets.yaml") .>: error calling include: template: .../secrets.yaml:4:19: executing ".../secrets.yaml" at <$.Release.Name>: nil pointer evaluating interface {}.Name
如何访问包含的模板内的变量？
TL;DR;
只需更换. with $使用全局范围而不是您创建的本地范围。
Example:
{{- include "my-chart.labels" $ | nindent 4 }}
说明
根据文档，https://helm.sh/docs/chart_template_guide/control_structs/#modifying-scope-using-with https://helm.sh/docs/chart_template_guide/control_structures/#modifying-scope-using-with:
我们可以使用 $ 从父级访问对象 Release.Name
范围。
当模板执行开始时，$被映射到根范围
并且在模板执行期间它不会改变
With range我们改变循环内的范围。的确，{{- include "my-chart.labels" . | nindent 4 }}将调用当前范围..
因此，如果您深入研究 helm 文档中的“范围”内容，您最终会找到这部分：https://helm.sh/docs/chart_template_guide/variables/ https://helm.sh/docs/chart_template_guide/variables/
以此为例：
{{- range .Values.tlsSecrets }}
apiVersion: v1
kind: Secret
metadata:
name: {{ .name }}
labels:
# Many helm templates would use `.` below, but that will not work,
# however `$` will work here
app.kubernetes.io/name: {{ template "fullname" $ }}
# I cannot reference .Chart.Name, but I can do $.Chart.Name
helm.sh/chart: "{{ $.Chart.Name }}-{{ $.Chart.Version }}"
app.kubernetes.io/instance: "{{ $.Release.Name }}"
# Value from appVersion in Chart.yaml
app.kubernetes.io/version: "{{ $.Chart.AppVersion }}"
app.kubernetes.io/managed-by: "{{ $.Release.Service }}"
type: kubernetes.io/tls
data:
tls.crt: {{ .certificate }}
tls.key: {{ .key }}
---
{{- end }}
