What are the best practices for using Prometheus with Docker Compose?

When using Prometheus with Docker Compose, it's important to define your services clearly and ensure proper networking.

Can you give me an example of a Docker Compose file for Prometheus?

Sure! Here's a simple example:

version: '3'
services:
  prometheus:
    image: prom/prometheus
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    ports:
      - "9090:9090"
    networks:
      - monitoring
networks:
  monitoring:
    driver: bridge

How do I configure Prometheus to scrape metrics from my application?

You need to specify the targets in your prometheus.yml file. For example:

scrape_configs:
  - job_name: 'my_app'
    static_configs:
      - targets: ['app:8080']

What are some common pitfalls to avoid when using Prometheus with Docker?

Common pitfalls include not properly configuring network settings, failing to set resource limits, and neglecting to secure your Prometheus instance.
