前言

• redis exporter是用來監控Redis一個Prometheus Client，提供相關redis的監控metrics

步驟

• 建立一個新的folder，命名redis
• 在redis目錄底下，建立docker-compose.yml
• docker-compose.yml 底下輸入

version: '3'
services:
  redis:
    restart: always
    container_name: redis
    image: redis:6.2.7-alpine
    ports:
      - 6379:6379
  redis-exporter:
    restart: always
    image: oliver006/redis_exporter:v1.45.0-alpine
    container_name: redis-exporter
    ports:
      - 9121:9121
    command:
      - '--redis.addr=redis://redis-server:6379'
      

• 執行docker-compose up -d，redis服務與redis exporter即可啟動

• 確認redis exporter服務，已經在執行輸入curl http://localhost:9121/metrics

λ curl http://localhost:9121/metrics
