Helm 分环境 values 管理与模板函数实践

示例 values-dev.yaml：env: dev image: repository: registry.example.com/app tag: dev-20250101 resources: requests: cpu: 200m memory: 256Mi extra: featureX: true 示例 values-prod.yaml：env: prod image: repository: registry.example.com/app tag: v1.2.3 resources: requests: cpu: 500m memory: 512Mi extra: featureX: false 模板片段（ConfigMap 与校验）：apiVersion: v1 kind: ConfigMap metadata: name: {{ include "app.fullname" . }}-config data: APP_ENV: {{ .Values.env | quote }} IMAGE_REPO: {{ required "image.repository required" .Values.image.repository | quote }} IMAGE_TAG: {{ default "latest" .Values.image.tag | quote }} EXTRA: | {{- toYaml .Values.extra | nindent 4 }} 以 dev 环境安装/升级：helm install app ./chart -f values-dev.yaml helm upgrade app ./chart -f values-dev.yaml 使用 tpl 渲染可模板化值：metadata: labels: rendered: {{ tpl "{{ .Values.env }}-label" . | quote }}
