我的普罗米修斯配置有什么问题？

Question

我正在尝试运行 kubernetes 集群上的 prometheus，我的 prometheus 配置通过 configmap 注入到 prometheus:

apiVersion: v1
kind: ConfigMap
metadata:
  name: prometheus-config
  namespace: monitoring
data:
  prometheus.yml: |
    global:
      scrape_interval: 10s
      scrape_configs:
      - job_name: 'kubelet'
        kubernetes_sd_configs:
        - role: node
        scheme: https
        tls_config:
          ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

但是prometheus pod无法启动，错误日志如下：

level=error ts=2020-07-04T02:27:32.831Z caller=main.go:758 err="error loading config from \"/etc/prometheus/prometheus.yml\": couldn't load configuration (--config.file=\"/etc/prometheus/prometheus.yml\"): parsing YAML file /etc/prometheus/prometheus.yml: yaml: unmarshal errors:\n  line 3: field scrape_configs not found in type config.plain"

我仔细看了prometheus的文档，没找到线索。

scrape_configs 应与 global 处于同一级别。

apiVersion: v1
kind: ConfigMap
metadata:
  name: prometheus-config
  namespace: monitoring
data:
  prometheus.yml: |
    global:
      scrape_interval: 10s
    scrape_configs:
    - job_name: 'kubelet'
      kubernetes_sd_configs:
      - role: node
      scheme: https
      tls_config:
        ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
