docker로 prometheus, grafana 사용하는 경우 설정 가이드

prometheus.yml

global:
  scrape_interval: 15s
  evaluation_interval: 15s
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093
rule_files:
scrape_configs:
  - job_name: "docker"
    static_configs:
      - targets: ["localhost:9090"]
    #추가
  - job_name: "spring-actuator"
    metrics_path: '/actuator/prometheus'
    scrape_interval: 1s
    static_configs:
    - targets: ['host.docker.internal:8080']

targets을 localhost:8080으로 하면 안됩니다. ㅠㅠ

• 참고: https://yoo-young.tistory.com/90

targets을 localhost:8080으로 하면 아래와 같은 결과가 나옵니다.

반드시 targets: ['host.docker.internal:8080']로 설정해 주세요!

docker-compose.yml

version: '3'
services:
  grafana:
    image: grafana/grafana:latest
    container_name: grafana
    restart: always
    ports:
      - "3000:3000"
    volumes:
      - grafana-data:/var/lib/grafana
      - ./grafana/provisioning/:/etc/grafana/provisioning/
    environment:
      - GF_SERVER_ROOT_URL=http://localhost:3000
      - GF_SECURITY_ADMIN_PASSWORD=admin
    depends_on:
      - prometheus

  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    restart: always
    ports:
      - "9090:9090"
    volumes:
      - ./prometheus/config:/etc/prometheus/
      - prometheus-data:/prometheus
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'

volumes:
  grafana-data:
  prometheus-data:

결과

http://localhost:9090/targets

감사합니다.
