kubernetes - 如何为数据源创建grafana configmap？

Question

我正在尝试使用 Kube-Prometheus-Stack helm chart https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack 中的 Grafana 实例为 Grafana 数据源创建配置映射
我知道仪表板，您可以使用此答案中列出的命令从 json 文件创建配置映射:stable/prometheus-operator - adding persistent grafana dashboards

wget https://raw.githubusercontent.com/percona/grafana-dashboards/master/dashboards/MongoDB_Overview.json
kubectl -n monitoring create cm grafana-mongodb-overview --from-file=MongoDB_Overview.json
kubectl -n monitoring label cm grafana-mongodb-overview grafana_dashboard=mongodb-overview

可以为 grafana 数据源做类似的事情吗？我目前有一个 datasource.yaml，其中包含以下几行:

    data:
      datasource-PRF1-Prometheus.yaml: |-
        apiVersion: 1
        datasources:
          - name: Test-Prometheus
            type: prometheus
            url: https://prometheus.url.net/
            access: Server
            isDefault: true
            basicAuth: true
            basicAuthPassword: password
            basicAuthUser: admin

但是，我无法使用它导入数据源，即使它创建了一个配置映射。

要通过 grafana 服务器组件加载数据，您需要在元数据字段中进行设置 grafana_datasource: "1" .
对于配置映射:

apiVersion: v1
kind: ConfigMap
metadata:
  name: example-grafana-datasource
  labels:
     grafana_datasource: "1"
     namespace: monitoring
data:
  datasource.yaml: |-
    apiVersion: 1
    datasources:
    - access: proxy
      basicAuth: false
      editable: false
      isDefault: false
      jsonData:
        authType: credentials
        defaultRegion: us-west-2
      name: CloudWatch
      type: cloudwatch

对于具有相同标签的 secret

apiVersion: v1
kind: Secret
metadata:
  name: influx-grafana-datasource
  labels:
     grafana_datasource: "1"
     namespace: monitoring
type: Opaque
stringData:
  influxdatasource.yaml: |-
    # config file version
    apiVersion: 1
    datasources:
      - name: influxdb
        type: influxdb
        access: proxy
        database: metrics_db
        user: metrics_read_user
        url: http://influx.example.com:8086/
        jsonData:
          timeInterval: "15s"
        secureJsonData:
          password: yourinfluxpassword
