gopaytech/vmware-filesd

镜像概述

本镜像基于Ansible VMware inventory代码修改，实现了Prometheus的文件式服务发现功能，通过VMware标签识别监控目标并生成JSON配置文件，供Prometheus读取使用。在大型VMware环境中可能存在一定性能延迟。

核心功能

1. 利用VMware标签筛选监控目标
2. 生成Prometheus兼容的文件发现配置（JSON格式）
3. 支持环境变量配置VMware连接信息与过滤条件
4. 可通过命令行直接调用或集成到Prometheus Operator部署

使用场景

• VMware虚拟化环境中Prometheus监控目标的自动发现
• 针对特定标签（如环境、组件类型）的监控目标筛选
• 集成node-exporter、pg-exporter等监控组件的自动配置

配置说明

镜像支持以下环境变量配置：

• HOSTNAME: VMware服务器地址
• USERNAME: VMware登录用户名
• PASSWORD: VMware登录密码
• OUTPUT: 生成的配置文件输出路径（如/opt/config/vmware-filesd.json）
• FILTER: 目标筛选条件（JSON格式，如{"environment": "staging"}）

部署示例

1. Prometheus Operator集成配置

yaml
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  labels:
    prometheus: po-prometheus-vmware-filesd
  name: po-prometheus-vmware-filesd
spec:
  containers:
    - name: vmware-filesd
      image: gopaytech/vmware-filesd:latest
      env:
        - name: HOSTNAME
          value: "10.0.0.1"
        - name: USERNAME
          value: "vmware-user"
        - name: PASSWORD
          value: "vmware-password"
        - name: OUTPUT
          value: "/opt/config/vmware-filesd.json"
        - name: FILTER
          value: '{"environment": "staging"}'
      volumeMounts:
        - name: config-out
          mountPath: /opt/config
          readOnly: false
  securityContext:
    fsGroup: 2000
    runAsNonRoot: true
    runAsUser: 1000
  serviceAccountName: po-prometheus-operator-prometheus
  serviceMonitorNamespaceSelector: {}
  serviceMonitorSelector:
    matchLabels:
      release: vmware-filesd
  additionalScrapeConfigs:
    name: additional-scrape-configs
    key: prometheus-additional.yaml

2. 命令行直接调用

bash
python3 main.py --hostname $HOSTNAME --username $USERNAME --password $PASSWORD --output $OUTPUT --loop --notls --filter "$FILTER"

3. 创建额外Scrape配置Secret

bash
kubectl create secret generic additional-scrape-configs --from-file=prometheus-additional.yaml

4. Prometheus Scrape配置示例

yaml
- job_name: "vmware/node-exporter"
  file_sd_configs:
    - files:
        - /etc/prometheus/config_out/vmware-filesd.json
  relabel_configs:
    - source_labels: [__address__]
      target_label: instance
    - source_labels: [__address__]
      target_label: __address__
      replacement: "${1}:9100"

- job_name: "vmware/pg-exporter"
  file_sd_configs:
    - files:
        - /etc/prometheus/config_out/vmware-filesd.json
  relabel_configs:
    - source_labels: [__address__]
      target_label: instance
    - source_labels: [component]
      regex: ^(?!(pg|postgres)$).*
      action: drop
    - source_labels: [__address__, component]
      target_label: __address__
      regex: "(.*);(pg)"
      replacement: "${1}:9187"
