Prerequisites

Before we begin, make sure you have the following:

A virtual machine or a dedicated device running Alpine Linux Latest
Root access to the device

Step 1: Update Packages

The first step is to update the package repository on your device. You can do this by running the following command:

# vi /etc/prometheus/prometheus.yml

Here, you can configure the endpoints that Prometheus will scrape and monitor, as well as the alerting rules. You can find more information on configuring Prometheus in the official documentation.

Step 4: Start Prometheus

Now that the configuration is complete, we can start Prometheus by running the following command:

# rc-update add prometheus
# /etc/init.d/prometheus start

This will start the Prometheus service and ensure that it starts automatically on boot.

Step 5: Verify Installation

To verify that Prometheus is running correctly, you can navigate to http://localhost:9090/ or http://<device-ip>:9090/ on your device's web browser. This should display the Prometheus web interface, where you can view the metrics and configure alerting rules.
