如何在作为主图一部分两个子图上应用custom-values.yaml

Question

图表：-

dependencies:
     - name: prometheus-operator
       version: 8.16.1
       repository: https://kubernetes-charts.storage.googleapis.com/
     - name: fluentd-elasticsearch
       version: 9.4.2
       repository: https://kiwigrid.github.io

Custom-values.yaml

# Change default node-exporter port
prometheus-node-exporter:
  service:
    port: 30206
    targetPort: 30206
prometheus:
  prometheusSpec:
    storageSpec:
       volumeClaimTemplate:
         spec:
           storageClassName: efs
           accessModes: ["ReadWriteOnce"]
           resources:
             requests:
               storage: 5Gi
         selector: {}
elasticsearch:
  hosts: ["https://vpc-logs-abcd:443"]

运行命令：-

helm install --namespace dependency test -f /root/custom-values.yaml  /root/customchart

错误/问题：- Custom-values.yaml未应用于图表!！使用“默认值”安装的图表

如上所述，要在子图中传递值，需要在dependent chart name部分下定义值，如下所示

prometheus-operator:
# Change default node-exporter port
  prometheus-node-exporter:
    service:
      port: 30206
      targetPort: 30206
  prometheus:
    prometheusSpec:
      storageSpec:
         volumeClaimTemplate:
           spec:
             storageClassName: efs
             accessModes: ["ReadWriteOnce"]
             resources:
               requests:
                 storage: 5Gi
           selector: {}

fluentd-elasticsearch:
  elasticsearch:
    hosts: ["https://vpc-logs-abcd:443"]

当Helm安装依赖关系图时，only the values under the dependency's name are made visible to that chart。例如，当prometheus-operator chart documentation列出配置值时，这些配置值需要在custom-values.yaml中的依赖项名称下面。

因此，您的值需要重新排列，如下所示：

prometheus-operator: # dependency name from requirements.yaml/chart.yaml
  prometheus:
    prometheusSpec:
      storageSpec: { ... } # as you have it
  prometheus-node-exporter:
    # (Some settings are under nodeExporter; "service" isn't listed
    # in the chart docs)
    ...

fluentd-elasticsearch: # settings for the other dependency
  elasticsearch:
    hosts: ["https://vpc-logs-abcd:443"]
