微服务间服务发现配置
在构建模型监控平台时,微服务间的通信是核心环节。本文将详细介绍如何通过Consul实现服务发现,并配置健康检查和负载均衡。
1. Consul服务注册配置
首先,在每个微服务启动时注册到Consul:
# docker-compose.yml
services:
model-service:
image: model-monitor:latest
environment:
- CONSUL_HOST=consul-server
- SERVICE_NAME=model-monitor
- SERVICE_PORT=8080
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
interval: 30s
timeout: 10s
retries: 3
2. 监控指标配置
为每个服务配置关键监控指标:
# prometheus.yml
scrape_configs:
- job_name: 'model-service'
consul_sd_configs:
- server: 'consul-server:8500'
services: ["model-monitor"]
metrics_path: '/metrics'
scrape_interval: 15s
3. 告警规则配置
在Alertmanager中设置服务可用性告警:
# alerting.yml
route:
receiver: 'slack-notifications'
receivers:
- name: 'slack-notifications'
slack_configs:
- send_resolved: true
text: "模型服务异常:{{ .CommonLabels.service }}"
alerts:
- alert: ServiceDown
expr: up == 0
for: 5m
labels:
severity: critical
annotations:
summary: "服务不可用"
description: "服务 {{ $labels.instance }} 已停止响应超过5分钟"
4. 配置复现步骤
- 启动Consul服务:
docker run -d --name consul-server -p 8500:8500 consul - 部署模型监控服务:
docker-compose up -d model-service - 验证服务发现:
curl http://localhost:8500/v1/health/service/model-monitor - 查看Prometheus抓取指标:
http://localhost:9090/targets
通过以上配置,可实现模型服务的自动发现、健康检查和告警通知,确保监控系统的稳定性。
