  1. Challenge

    Configure the Docker Daemon to Serve Prometheus Metrics
    1. Log in to the Docker server.

    2. Edit the Docker config file:

      sudo vi /etc/docker/daemon.json
      
    3. Add configuration to enable experimental mode and set the metrics address:

      {
        "experimental": true,
        "metrics-addr": "10.0.1.102:9323"
      }
      
    4. Restart Docker to load the new configuration:

      sudo systemctl restart docker
      
    5. Verify Docker is serving Prometheus metrics:

      curl 10.0.1.102:9323/metrics
      
  2. Challenge

    Configure Prometheus to Scrape Docker Metrics
    1. Log in to the Prometheus server.

    2. Edit the Prometheus config:

      sudo vi /etc/prometheus/prometheus.yml
      
    3. Under the scrape_configs section, add a scrape configuration for Docker:

      - job_name: 'Docker'
        static_configs:
        - targets: ['limedrop-docker:9323']
      
    4. Restart Prometheus to load the new configuration:

      sudo systemctl restart prometheus
      
    5. Use the expression browser to verify you can see Docker metrics in Prometheus. You can access the expression browser in a web browser at http://<PROMETHEUS_SERVER_PUBLIC_IP>:9090.

    6. Run a query to view some Docker metric data:
