How do I set up Prometheus using Docker Compose?

To set up Prometheus with Docker Compose, you'll need to create a docker-compose.yml file. Would you like a sample configuration?

Yes, please provide a sample configuration.

Here's a basic example:

version: '3'
services:
  prometheus:
    image: prom/prometheus
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    ports:
      - '9090:9090'

This will run Prometheus on port 9090. Do you need help with the prometheus.yml file?

Yes, what should I include in the prometheus.yml file?

In your prometheus.yml, you can define your scrape configurations. Here's a simple example:

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'my_service'
    static_configs:
      - targets: ['my_service:8080']

This will scrape metrics from my_service every 15 seconds.
