自动将新的节点导出器添加到prometheus.yml的目标数组中

Question

我的环境中有一个基本的prometheus.yml文件，即..

###
apiVersion: v1
kind: ConfigMap
metadata:
  creationTimestamp: null
  name: prometheus-core
data:
  prometheus.yml: |
    global:
      scrape_interval: 10s
      scrape_timeout: 10s
      evaluation_interval: 10s

    rule_files:
      - '/etc/prometheus-rules/*.rules'

    scrape_configs:
       # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
      - job_name: 'prometheus'

        # Override the global default and scrape targets from this job every 5 seconds.
        scrape_interval: 5s

        # metrics_path defaults to '/metrics'
        # scheme defaults to 'http'.

        static_configs:
          - targets: ['localhost:9090'] 

现在，如果我向我的环境添加新节点，我的prometheus.yml文件应该自动更新，并将节点添加到下面的目标，即

###
apiVersion: v1
kind: ConfigMap
metadata:
  creationTimestamp: null
  name: prometheus-core
data:
  prometheus.yml: |
    global:
      scrape_interval: 10s
      scrape_timeout: 10s
      evaluation_interval: 10s

    rule_files:
      - '/etc/prometheus-rules/*.rules'

    scrape_configs:
       # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
      - job_name: 'prometheus'

        # Override the global default and scrape targets from this job every 5 seconds.
        scrape_interval: 5s

        # metrics_path defaults to '/metrics'
        # scheme defaults to 'http'.

        static_configs:
          - targets: ['localhost:9090','12.10.17.6:9100','12.10.17.19:9100'] 

任何人都可以建议我如何实现这个目标吗？

Answer 1

Prometheus支持Kubernetes服务发现机制，有关详细信息，请参阅documentation。

因此，您应该添加与此类似的部分，而不是static_configs部分：

scrape_configs:
- job_name: 'kubernetes-service-endpoints'

  kubernetes_sd_configs:
  - role: endpoints

...

请参阅此example configuration file了解其完成情况。
