链接：prometheus-operator/Documentation/additional-scrape-config.md at · GitHub

prometheus 实例增加如下配置：

# kubectl edit prometheus example-prometheus -n monitoring

spec:
  additionalScrapeConfigs:
    name: additional-scrape-configs
    key: prometheus-additional.yaml

prometheus-additional.yaml 配置如下：

- job_name: "prometheus"
  static_configs:
  - targets: ["localhost:9090"]
# 生成 secrete config yaml
kubectl create secret generic additional-scrape-configs --from-file=prometheus-additional.yaml --dry-run=client -oyaml > additional-scrape-configs.yaml

# 执行命令生成 secrete
kubectl apply -f additional-scrape-configs.yaml -n monitoring

# 查看生成的 secrete 内容
kubectl -n monitoring get secrets additional-scrape-configs -o jsonpath='{.data.prometheus-additional\.yaml}' | base64 -d


prometheus operator 配置 remote_write

kubectl -n monitoring edit prometheus k8s
# 修改成如下配置
spec:
  remoteWrite:
  - url: http://vminsert:8480/insert/0/prometheus/
 
# 查看config
# secrete 文件内容经过 gzip 压缩，要查看的话需要解压
kubectl -n monitoring get secrets prometheus-k8s -o jsonpath='{.data.prometheus\.yaml\.gz}' | base64 -d | gzip -d

prometheus operator 配置 external_labels

# 编辑 prometheus 实例
kubectl edit prometheus k8s -n monitoring

# 增加如下配置
spec:
  externalLabels:
    cluster: "test-1"
    environment: "production"
