根据 Prometheus-operator文档,我们应该能够通过秘密文件轻松提供我们的附加配置。有人真的成功了这一步吗?我有几个问题:
- 这些配置将出现在 prometheus pod 的什么位置?
- 这个配置应该是prometheus配置文件的形式还是只是列出额外的scrape条目
- 我们可以通过提供其他文件(json 配置)
file_sd_configs:
吗?如果可以,如何将这些文件提供到 prometheus 清单文件中?
不管这些问题如何,我都很难添加额外的配置。我基本上遵循了 文档中的确切步骤,这是我的观察结果:
- 这是我的新配置
cat prometheus-additional.yaml
- job_name: "prometheus-custom"
static_configs:
- targets: ["localhost:9090"]
- 添加新的秘密文件
kubectl create secret generic additional-scrape-configs --from-file=prometheus-additional.yaml
- 使用附加配置创建 prometheus.yml 文件
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
name: prometheus
spec:
replicas: 2
resources:
requests:
memory: 400Mi
additionalScrapeConfigs:
name: additional-scrape-configs
key: prometheus-additional.yaml
- 部署 prometheus.yaml
kubectl apply -f prometheus.yaml
- 检查日志,没有迹象表明我的新配置
kubectl logs prometheus-prometheus-0 -c prometheus

而且,当我登录 prometheus pod 时,我也看不到任何其他配置,当我检查我的 prometheus Web 控制台时,我也看不到任何配置。
