How do I set up Prometheus using Docker?

To set up Prometheus using Docker, you can start by pulling the Prometheus image from Docker Hub. Use the command: docker pull prom/prometheus.

What configuration do I need for Prometheus?

You'll need a prometheus.yml configuration file. This file defines the scrape targets and other settings. You can mount it as a volume when running the container.

Can you show me an example of the configuration file?

Sure! Here's a basic example:

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

How do I run the Prometheus container with this configuration?

You can run the container with the following command:

docker run -d --name prometheus -p 9090:9090 -v /path/to/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
