How do I set up Prometheus with Docker?

To set up Prometheus with Docker, you can use the following steps: 1. Pull the Prometheus image from Docker Hub. 2. Create a configuration file for Prometheus. 3. Run the Prometheus container with the configuration file mounted.

What should be in the configuration file?

The configuration file should include the scrape configuration for your targets. Here's a basic example:

global:
  scrape_interval: 15s

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

How do I run the container with the config file?

You can run the container using the following command:

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

Can I access the Prometheus UI?

Yes, once the container is running, you can access the Prometheus UI by navigating to http://localhost:9090 in your web browser.
